Description:
CROSS-REFERENCE TO RELATED APPLICATIONS 
     This application having attorney docket number 339471/180314US02 and entitled “Multi-Layer Nursing Bra And Nursing Bra System,” claims the benefit of priority of U.S. Provisional Application 62/822,479, filed Mar. 22, 2019, and entitled “Multi-Layer Nursing Bra And Nursing Bra System,” the entirety of which is incorporated by reference herein. 
    
    
     TECHNICAL FIELD 
     Aspects herein relate to a multi-layer nursing bra and a nursing bra system. 
     BACKGROUND 
     Traditionally, nursing bras comprise openable cup portions that are held closed by clasps. The nursing bras may be worn under upper-body garments or other nursing garments, however, due to the clasping system, traditional nursing bras may be hard to operate single handedly, or the clasps may be prone to getting stuck, or cause discomfort by creating undesirable pressure points. In addition, the upper-body garment that is worn over the nursing bra may need to be pulled upward from its bottom hem to expose the nursing bra which may present modesty concerns.

     DETAILED DESCRIPTION 
     The subject matter of the present invention is described with specificity herein to meet statutory requirements. However, the description itself is not intended to limit the scope of this disclosure. Rather, the inventors have contemplated that the claimed or disclosed subject matter might also be embodied in other ways, to include different steps or combinations of steps similar to the ones described in this document, in conjunction with other present or future technologies. Moreover, although the terms “step” and/or “block” might be used herein to connote different elements of methods employed, the terms should not be interpreted as implying any particular order among or between various steps herein disclosed unless and except when the order of individual steps is explicitly stated. 
     Nursing bras and garments, particularly those for use in the postpartum period, are often complex and cumbersome, having bulky components that are difficult to use and uncomfortable for the wearer. Further, nursing garments are often not made for active women, forcing active women to sacrifice functionality for comfort and vice versa. Some women choose to sacrifice exercise altogether during pregnancy and/or post-pregnancy because of a lack of functional and comfortable athletic wear. The multi-layer nursing bra and multi-layer nursing bra system disclosed herein allow a wearer to easily access one or more breasts when engaging in activities such as, for example, nursing and/or pumping, while also eliminating bulky components such as clasps and wires. Thus, the wearer can more easily transition from exercise and other day-to-day activities to nursing and/or pumping without sacrificing comfort and overall functionality of the garments. 
     At a high level, aspects herein are generally directed to a multi-layer nursing bra and a multi-layer nursing bra system having various elements that contribute to the operation of the multi-layer nursing bra and multi-layer nursing bra system, both independently of, and in combination with, one another. For example, the multi-layer nursing bra generally includes an inner layer and an outer layer positioned over the inner layer. In some instances, one of the inner or outer layers may be substantially Y-shaped or substantially triangular shaped, as will be described herein. Various aspects of the inner and outer layers of the multi-layer nursing bra are movable with respect to one another to allow for easy exposure of one or more breasts and/or nipple area of the wearer. The multi-layer nursing bra system generally includes the multi-layer nursing bra and an upper-body garment layered over the multi-layer nursing bra. The upper-body garment generally includes a nursing opening that is movable between a closed state and an open state for easy access to the multi-layer nursing bra and one or more breasts of the wearer. 
     In one example, the multi-layer nursing bra includes a front portion having an inner layer (also referred to as a first textile layer) and an outer layer (also referred to as a Y-shaped outer layer, or a second textile layer). The inner layer extends between an upper edge (also referred to as a first superior edge) and a lower edge (also referred to as a first inferior edge). The outer layer covers at least a portion of the inner layer and comprises a right edge (also referred to as a first side edge) extending between an upper right portion (also referred to as a first superior terminal end) and a lower central portion (also referred to as a third inferior terminal end), a left edge (also referred to as a second side edge) extending between an upper left portion (also referred to as a second superior terminal end) and the lower central portion, and an upper edge (also referred to as second superior edge) extending between the upper right portion and the upper left portion. In some instances, the right edge and the left edge converge as they extend toward the lower central portion of the outer layer. The right edge and the left edge of the outer layer are both moveable relative to the inner layer along at least a midpoint of the right edge and along at least a midpoint of the left edge of the outer layer. In some instances, the multi-layer nursing bra also includes an underband that extends from the lower edge of the inner layer. The underband may be integral with the inner layer or may otherwise be attached thereto. Further, when the underband is provided, the lower central portion of the outer layer is secured to a central region of the underband (also referred to as a mid-area of the underband). 
     In another example, the multi-layer nursing bra includes a front portion having an inner layer and an outer layer. The inner layer has a right edge extending between an upper right portion and a lower central portion of the inner layer, a left edge extending between an upper left portion and the lower central portion of the inner layer, and an upper edge extending between the upper right portion and the upper left portion. In some instances, the right edge and the left edge converge as they extend toward the lower central portion of the inner layer. The outer layer is a cross-over or wrap style layer having a right-side outer layer and a left-side outer layer, in which a medial portion of the right-side outer layer and a medial portion of the left-side outer layer overlap at a central region of the front portion. The right-side outer layer has a right-side upper edge and a right-side lower edge, and the left-side outer layer has a left-side upper edge and a left-side lower edge. The right-side upper edge of the right-side outer layer and the left-side upper edge of the left-side outer layer are both moveable relative to the inner layer along at least a midpoint of the right edge and along at least a midpoint of the left edge of the inner layer. 
     Optionally, the multi-layer nursing bra may also include a back portion that continuously extends from the front portion. Alternatively, in some instances, the multi-layer nursing bra can include a right wing band (also referred to as a first wing band) extending from the right side (also referred to as a first lateral side) of the front portion and a left wing band (also referred to as a second wing band) extending from the right side (also referred to as the second lateral side) of the front portion. In some examples, the right wing band includes a first component of an adjustable closure mechanism and the left wing band includes a second component of the adjustable closure mechanism. In operation, the first and second components of the adjustable closure mechanism may be releasably coupled to each other. 
     Aspects herein are also directed to a method for manufacturing the multi-layer nursing bra. The method includes forming the front portion of the multi-layer nursing bra by positioning the outer layer over the inner layer, where the inner surface of the outer layer is positioned adjacent to or overlies at least a portion of the outer surface of the inner layer. In some instances, this step is followed by, for example, affixing the lower central portion of the outer layer to a lower central portion of the inner layer. In other instances, the lower central portion of the outer layer is affixed to a discrete area of the underband, which is optionally affixed along a length of the lower edge of the inner layer. In yet other instances, the underband may be integral with the inner layer. By “integral,” it is to be understood that the underband is formed with the inner layer in a single textile forming event such as, for example, knitting, weaving, braiding, and the like. In other words, when the underband is integral with the inner layer, the underband seamlessly and continuously extends from the inner layer and does not need to be attached to the inner layer by stitching, bonding, and the like. In instances where the multi-layer nursing bra includes a back portion and/or wing bands, the underband may also be integral with the back portion and/or the wing bands. 
     Additionally, aspects herein are also directed to a multi-layer nursing bra system comprised of the multi-layer nursing bra and an upper-body garment. The multi-layer nursing bra may be constructed as described above and may be configured to be worn under the upper-body garment. In some instances, the upper-body garment includes a front portion and a back portion defining at least a neck opening and a torso opening. In example aspects, the front portion is measured from a first side seam to a second side seam. The first side seam generally extends from an inferior edge of a right arm or sleeve opening of the upper-body garment to the torso opening of the upper-body garment. The second side seam generally extends from an inferior edge of a left arm or sleeve opening of the upper-body garment to the torso opening of the upper-body garment. When the upper-body garment comprises a seamless construction (i.e., there are no side seams, or seams affixing or attaching the front portion to the back portion), the front portion is measured from a first location adjacent to the inferior edge of the right arm or sleeve opening to a second location adjacent to the inferior edge of the left arm or sleeve opening. 
     As described above, in some instances, the upper body garment includes a nursing opening. The nursing opening is positioned on the front portion of the upper body garment below a front edge defining the neck opening. The nursing opening substantially extends across the width of the front portion between a first lateral side of the front portion at or near the first side seam to a second lateral side of the front portion at or near the second side seam. In accordance with aspects herein, the term “substantially” when used to describe the nursing opening means that the nursing opening horizontally extends (i.e., orthogonal to a head-to-toe axis of a wearer) at least about 65% of the width of the front aspect, at least about 70% of the width of the front aspect, at least about 75% of the width of the front aspect, at least about 80% of the width of the front aspect, at least about 85% of the width of the front aspect, at least about 90% of the front aspect, or at least about 95% of the front aspect. As used herein, the term “about” means within ±5% of a designated value. The nursing opening in accordance with aspects herein may also be defined by an upper perimeter edge and a lower perimeter edge that may be overlapped when the nursing opening is in a closed state or first state. 
     Further, aspects herein are also directed to a method of using the multi-layer nursing bra system described above. For example, the wearer may first don the multi-layer nursing bra over an upper torso area of the wearer such that the front portion of the multi-layer nursing bra is positioned over the wearer&#39;s bust for providing support, as will become more apparent with respect to the figures. The upper-body garment can then be donned over the multi-layer nursing bra such that the nursing opening of the upper-body garment is radially aligned with the front portion of the multi-layer nursing bra. 
     As briefly described above, the positioning of the multi-layer nursing bra and the upper-body garment is advantageous because it provides easy access to the breast area of the wearer and may provide more modesty than many conventional maternity and/or nursing garments. For instance, instead of the wearer having to pull up the bottom hem of the upper-body garment to access the opening in the multi-layer nursing bra, the wearer can utilize the nursing opening of the upper-body garment. This may not only be more comfortable, but it may also allow for a more modest breast feeding experience for the wearer. Thus, the multi-layer nursing bra system described herein provides both a functional and comfortable multi-layer nursing bra and upper-body garment to the wearer. 
     Unless indicated otherwise, all measurements provided herein are taken when the bra and/or garment is at standard ambient temperature and pressure (298.15 K and 100 kPa) and the bra and/or garment is in a resting state (e.g., an unstretched state). 
       FIG. 1  is a front view  10  of an example multi-layer nursing bra  100  in a closed state. As shown, the multi-layer nursing bra  100  comprises a front portion  102  including an inner layer  104  and an outer layer  106 . As shown, the outer layer  106  is overlying or positioned adjacent to the inner layer  104 , as will become more apparent with respect to  FIG. 2 . As shown in  FIG. 1 , the inner layer  104  has an upper edge  112 , a lower edge  114 , a right side edge  210 , and a left side edge  212 . The outer layer  106  has an upper right portion  120 , an upper left portion  122 , and a lower central portion  124  that are positioned so that the outer layer  106  forms a substantially upright “Y-shape” or a triangular shape and, in particular, an upside down triangular shape (i.e., a triangular shape having the base positioned superior to the apex) with the upper right portion  120  and the upper left portion  122  located above the lower central portion  124 . As used herein, the term substantially upright Y-shape means a shape corresponding generally to the letter “Y” and having two upright arms and a stem. It is not meant to imply any specific characteristics of the edges extending between the upright arms and the stem. The outer layer  106  has an upper edge  128  that extends between the upper right portion  120  and the upper left portion  122 , a right edge  125  that extends between the upper right portion  120  and the lower central portion  124  having a midpoint  131 , and a left edge  126  that extends between the upper left portion  122  and the lower central portion  124  having a midpoint  133 . The upper edge  128  of the outer layer  106  is generally located above the upper edge  112  of the inner layer  104 . In accordance with aspects herein, the right edge  125 , the left edge  126 , and/or the upper edge  128  of the outer layer  106  are curved inwardly with respect to a central area  230  of the outer layer  106 . However, in other aspects, one or more of the right edge  125 , the left edge  126 , and/or the upper edge  128  of the outer layer  106  may be curved outwardly with respect to the central area  230  and/or may be substantially straight. 
     Further, in some instances, the right edge  125 , the left edge  126 , and/or the upper edge  128  of the outer layer  106  are substantially detached from or not seamed to the inner layer  104 . In accordance with aspects herein, “substantially,” describes that at least about 70% of the right edge  125 , the left edge  126 , and/or the upper edge  128  of the outer layer  106  are detached or “free” from the inner layer  104 , at least about 75% of the right edge  125 , the left edge  126 , and/or the upper edge  128  of the outer layer  106  are detached or “free” from the inner layer  104 , at least about 80% of the right edge  125 , the left edge  126  and/or the upper edge  128  of the outer layer  106  are detached or “free” from the inner layer  104 , at least about 85% of the right edge  125 , the left edge  126  and/or the upper edge  128  of the outer layer are detached or “free” from the inner layer  104 , or at least about 90% of the right edge  125 , the left edge  126  and/or the upper edge  128  of the outer layer  106  are detached or “free” from the inner layer  104 . As used herein, the term “about” means within ±10% of a reference value. Because at least the right edge  125  and the left edge  126  of the outer layer  106  are substantially detached from the inner layer  104 , at least a midpoint  131  of the right edge  125  and at least a midpoint  133  of the left edge  126  can be independently manipulated or moved with respect to the inner layer  104 . In some instances, the upper edge  112  of the inner layer  104  is also substantially detached from the outer layer  106  and thus, can also be independently manipulated or moved with respect to the outer layer  106 . This, in turn, allows the wearer to easily expose one or more breast by manipulating the inner layer  104  and the outer layer  106 . 
     Because of the dynamic nature of the multi-layer nursing bra  100 , it is contemplated that the inner layer  104  and the outer layer  106  of the multi-layer nursing bra  100  may both be comprised of elastically resilient textile materials that may be woven, knit, braided, or otherwise formed, such as for example double knit, warp knit mesh, jersey knit, and the like. The base materials forming the elastically resilient textiles may include, for example, recycled polyester, elastomeric yarns (e.g. spandex), and the like. In accordance with certain aspects, the outer layer  106  and the inner layer  104  of the multi-layer nursing bra  100  may be comprised of the same textile material. In accordance with other aspects, the outer layer  106  and the inner layer  104  of the multi-layer nursing bra  100  may be comprised of different textile materials having substantially the same elasticity, or in other words, the inner layer  104  and the outer layer  106  may have equal moduli of elasticity. In yet other aspects, the outer layer  106  and the inner layer  104  of the multi-layer nursing bra  100  may be comprised of different textile materials having different elasticity properties, or in other words, the modulus of elasticity of the inner layer  104  may be different from the modulus of elasticity of the outer layer  106 . As well, the inner layer  104 , or both the inner layer  104  and the outer layer  106  may have moisture management properties, anti-bacterial properties, odor resistant properties, and the like. With respect to moisture-management properties, these may be imparted by, for example, utilizing a denier differential mechanism, a chemical treatment, and the like. 
     The multi-layer nursing bra can be in a closed state as shown in  FIG. 1 , or in an open state as shown in  FIG. 7 . In the closed state as shown in  FIG. 1 , the right edge  125  and the left edge  126  of the outer layer  106  are positioned below the upper edge  112  of the inner layer  104 , as shown by the dashed line to indicate that it is generally hidden from view in the closed state. 
     In some instances, the multi-layer nursing bra  100  also includes an underband  108  having an upper edge  130  and a lower edge  132 . Thus, when assembled, the outer layer  106  may be secured by sewing, bonding, or other affixing technologies to the inner layer  104  by affixing the upper right portion  120  of the outer layer  106  to a portion  220  of the right side edge  210  of the inner layer  104  and affixing the upper left portion  122  of the outer layer  106  to a portion  222  of the left side edge  212  of the inner layer  104 . Similarly, the upper edge  130  of the underband  108  may be secured to the lower edge  114  of the inner layer  104  along a length of the lower edge  114  of the inner layer  104 . In some instances, the underband  108  extends at least along the lower edge  114  of the front portion  102 . In instances where a back portion  410  continuously extends from the inner layer  104  of the front portion  102 , as shown in  FIG. 4A , for example, the underband  108  continuously extends along an inferior edge of the back portion  410 . Alternatively, if the back portion is comprised of a right wing band  422  and a left wing band  420 , as shown in  FIG. 4B , for example, the underband  108  continuously extends from the front portion  102  to a first end of the right wing band  422  along an inferior edge of right wing band  422 , and from the front portion  102  to a second end of the left wing band  420  along an inferior edge of left wing band  420 . In other words, the underband  108  may circumferentially extend around the inferior edge(s) of the front portion  102  and the back portion  410  and/or right wing band  422  and left wing band  420 . 
     The lower central portion  124  of the outer layer  106  may also be secured to the upper edge  130  of the underband  108  at a mid-area  224  of the underband  108 . The lower central portion  124  of the outer layer  106  is generally equidistant along a horizontal axis between the upper right portion  120  and the upper left portion  122 . Consequently, the mid-area  224  of the underband  108  to which the outer layer  106  is affixed by way of the lower central portion  124 , is generally equidistant along the horizontal axis between the upper right portion  120  and the upper left portion  122 . In other words, the mid-area  224  is generally equidistant from the portion  220  of the right side edge  210  and the portion  222  of the left side edge  212  of the inner layer  104 . As shown in  FIG. 1 , a distance  127  measured from the portion  220  to a perpendicular line extending from the mid-area  224  of the underband  108  is substantially equal to a distance  129  measured from the portion  222  to the perpendicular line extending from the mid-area  224 . The term “substantially equal” when used to describe distance and/or length in accordance with aspects herein means that at least two measured distances and/or lengths are at least about 90% the same, or that the distances and/or lengths are at least about 95% the same, or that the distances and/or lengths are at least about 98% the same. 
     As shown in  FIG. 1 , the multi-layer nursing bra  100  may also optionally comprise a first shoulder strap  110   a  and a second shoulder strap  110   b . Although the first and second shoulder straps  110   a  and  110   b  are depicted as having a crisscross configuration in the back of the multi-layer nursing bra  100 , it is contemplated that the first and second shoulder straps  110   a  and  110   b  may have other configurations such as, for example, parallel or T-shape. In other instances, the multi-layer nursing bra  100  may include only one strap such as in a halter-type configuration or may include no straps such as in a strapless configuration without departing from the aspects disclosed herein. 
       FIG. 2  shows a deconstructed view  20  of the front portion  102  of the multi-layer nursing bra  100 . As shown in  FIG. 2 , the inner layer  104  has a first or outer surface  202  and a second or inner surface  204  opposite the outer surface  202 . Similarly, the outer layer  106  has a first or outer surface  206  and a second or inner surface  208  opposite the outer surface  206 . When the outer layer  106  is overlying or positioned on top of the inner layer  104 , the inner surface  208  of the outer layer  106  is positioned adjacent to the outer surface  202  of the inner layer  104 . As shown in  FIG. 1 , portions  140   a  and  140   b  of the outer surface  202  of the inner layer  104  are not covered by the outer layer  106  when the outer layer  106  is layered on top of the inner layer  104 . 
       FIG. 3  shows an interior view  30  of the multi-layer nursing bra  100 . As shown, the inner surface  204  of the inner layer  104  and a portion of the inner surface  208  of the outer layer  106  are configured to face a wearer when the multi-layer nursing bra  100  is worn. A seamless surface such as the inner surface  204  of the inner layer  104  that is in direct contact with the wearer&#39;s skin may improve comfort by eliminating pressure points that may be caused by seams or clasps. The seamless surface may also provide support to the bust area of the wearer when the multi-layer nursing bra  100  is worn, which can be seen from the lateral view  50  of the multi-layer nursing bra  100  shown in  FIG. 5 . In some instances, such as when additional protection is desired, the inner layer  104  may include one or more pad pockets configured to align with a breast area of the wearer when then multi-layer nursing bra  100  is worn by the wearer. Each of the one or more pad pockets is configured to accommodate, for example, nursing pads or modesty pads for covering the nipples of the wearer and/or absorbing any milk leakage, breast enhancement inserts, and the like. Alternatively or additionally, the inner layer  104  may comprise a spacer material that is positioned to align with, for instance, the portion of a wearer&#39;s breast surrounding the nipple to provide modesty, breast enhancement, and/or to absorb moisture resulting from sweat from exercise and/or milk leakage during nursing. 
       FIGS. 4A and 4B  depict rear views  40  and  42  respectively of two example multi-layer nursing bra configurations. For example,  FIG. 4A  depicts a rear view  40  of a multi-layer nursing bra  400  having a single piece back portion  410  extending from the front portion  102 , or the inner layer  104  of the front portion  102 .  FIG. 4B  depicts a rear view  42  of a multi-layer nursing bra  402  having a left wing band  420  extending from a left side of the front portion  102 , or the left side of the inner layer  104  of the front portion  102 , and a right wing band  422  extending from the right side of the front portion  102 , or the right side of the inner layer  104  of the front portion  102 . 
     It is contemplated that in either multi-layer nursing bra configuration, the front portion  102  of the multi-layer nursing bras  400  and  402  will cooperate with the back portion  410 , or the left wing band  420  and the right wing band  422 , respectively, to define the right side edge  210  and the left side edge  212 . The right side edge  210  and the left side edge  212  define underarm perimeter portions that are configured to extend along an underarm portion of a wearer, as shown in  FIGS. 1 and 5 , when the multi-layer nursing bras  100 ,  400 , or  402  are in their as-worn configurations. Further, as shown in  FIG. 4A , the underband  108 , may extend from the front portion  102  to the back portion  410  and may be attached at underband edge  440  of the back portion  410 . Alternatively, as shown in  FIG. 4B , the underband  108  may extend from a left side of the front portion  102  to a first end  430  of the left wing band  420  and is attached to the left wing band  420  at underband edge  442 . Similarly, the underband  108  may extend from a right side of the front portion  102  to a second end  432  of the right wing band  422  and is attached to the right wing band  422  at underband edge  444  of the right wing band  422 . 
     In some instances, each of the left wing band  420  and the right wing band  422  of multi-layer nursing bra  402  may comprise a respective component of an adjustable closure mechanism  424 . For example, the first end  430  of the left wing band  420  may comprise a first component(s)  426  of the adjustable closure mechanism  424 , and the second end  432  of the right wing band  422  may comprise a second component(s)  428  of the adjustable closure mechanism  424 , in which the first component  426  is adapted to be releasably coupled to the second component  428 . Further, as shown, each of the first and second shoulder straps  110   a  and  110   b  may comprise a first end  116   a  and  116   b , respectively, coupled to or extending from the front portion  102  of the multi-layer nursing bras  100 ,  400 , and  402 , as described above. Each of the first and second shoulder straps  110   a  and  110   b  also include a second end  118   a  and  118   b , respectively, coupled to or extending from the back portion  410  of the multi-layer nursing bra  400 , as shown in  FIG. 4A , or the respective left and right wing bands  420  and  422  of the multi-layer nursing bra  402 , as shown in  FIG. 4B . 
     In some instances, the multi-layer nursing bra  400  may be donned by pulling the multi-layer nursing bra  400  from the shoulders downward onto the upper torso area of the wearer, as is done with conventional sport bras. On the other hand, the multi-layer nursing bra  402  may be donned by opening the adjustable closure mechanism  424 , positioning the front portion  102  of the multi-layer nursing bra  402  over the bust area of the wearer, wrapping the left and right wing bands  420  and  422  around the upper torso of the wearer, and affixing the first and second ends  430  and  432  of the left and right wing bands  420  and  422  to each other by releasably engaging the first and second components  426  and  428  of the adjustable closure mechanism  424 . 
     As shown in  FIG. 5 , the first and second shoulder straps  110   a  and  110   b  in combination with the right side edge  210  and left side edge  212  of the inner layer  104 , may form in part arm openings  510  through which the wearer may extend her arms when wearing one of the multi-layer nursing bras  100 ,  400 , or  402  in accordance with aspects herein. Further, it is contemplated that, regardless of whether the back portion  410  is provided as a single piece, as shown in  FIG. 4A , or as left and right wing bands  420  and  422 , as shown in  FIG. 4B , the back portion  410  or the left and right wing bands  420  and  422 , may be coupled to the inner layer  104  by attachment means such as stitching, bonding, and the like. Alternatively, the back portion  410  or the left and right wing bands  420  and  422  may seamlessly and continuously extend from the inner layer  104 , as a single piece. As shown in  FIG. 5 , the underband  108  may be continuously affixed/attached to an underband edge  213  of the back portion  410 , as shown in  FIG. 4A , or the left and right wing bands  420  and  422 , as shown in  FIG. 4B . In accordance with aspects herein, “seamlessly and continuously extend(s)” infers that there are no attachment means (i.e., no seam lines) because the inner layer  104  and the back portion  410 , or the left and right wing bands  420  and  422 , are formed from a single piece of material. 
     In another example, in accordance with aspects herein the inner layer  104  seamlessly and continuously extends between the right side edge  210  and the left side edge  212 , and the outer layer  106  seamlessly and continuously extends between the right edge  125  and the left edge  126 . To describe this differently, the inner layer  104  and the outer layer  106  may each be formed from a single piece of material void of any seams or attachment means that connect two or more pieces of material together. The term “seamlessly and continuously extend(s)” also encompasses situations where one or more of the inner layer  104 , the outer layer  106 , the back portion  410 , or the left and right wing bands  420  and  422  may optionally be provided with slits, holes, perforations, and the like to provide, for example, increased breathability and/or aesthetic appeal to the garment. In some instances, the inner layer  104 , the outer layer  106 , the back portion  410 , and/or the left and right wing bands  420  and  422  may be comprised of a mesh type material and/or may comprise moisture management properties to improve comfort. This may be especially helpful when the wearer is exercising or performing other physically demanding tasks that increase the wearer&#39;s body temperature. 
       FIGS. 6 and 7  depict the multi-layer nursing bra  100  transitioning from the closed state to an open state. Initially, as shown in  FIG. 6 , in order to open a right side of the multi-layer nursing bra  100 , an upward force is exerted on at least the midpoint  131  of the right edge  125  of the outer layer  106 , thereby exposing at least a portion of the upper edge  112  of the inner layer  104 . Once the upper edge  112  of the inner layer  104  is exposed, a downward force is exerted on at least the exposed portion of the upper edge  112  of the inner layer  104  to form an opening  700 . When the opening  700  is formed, at least a portion of the right edge  125  of the outer layer  106  is positioned above at least a portion of the upper edge  112  of the inner layer  104 . In other words, the opening  700  is between at least one of the right edge  125  or the left edge  126  of the outer layer  106  and the upper edge  112  of the inner layer  104 . The opening  700  provides access to the nipple area of the wearer for breast feeding or pumping, for example. This arrangement offers several advantages such as, for example, eliminating the need for hard-to-manipulate clasps and uncomfortable pressure points resulting from the clasps, and allowing for easy manipulation, particularly single-handed manipulation, of the multi-layer nursing bra  100 . 
     Once the breast feeding or pumping is completed, the multi-layer nursing bra  100  may be returned to the closed state by exerting an upward force on the upper edge  112  of the inner layer  104  and exerting a downward force on the right edge  125  of the outer layer  106 , where the right edge  125  of the outer layer  106  is positioned below the upper edge  112  of the inner layer  104  when the opening  700  is closed. Similarly, for the left side, an upward force may be exerted on at least the midpoint  133  of the left edge  126  of the outer layer  106 , thereby exposing at least a portion of the upper edge  112  of the inner layer  104 , to form an opening, and closing the opening in a similar manner as described above for the right side. 
       FIGS. 8 and 9  show a frontal view  80  and a rear view  90  of an upper-body garment  800 , as illustrated in accordance with aspects herein. The upper-body garment  800  is configured to be worn over the multi-layer nursing bra  100 , as a nursing bra system  1100 , as will become more apparent with respect to  FIG. 11 . As shown, the upper-body garment  800  comprises a front portion  810  including an upper panel  808 , a separate lower panel  806 , and a back portion  812 . The front portion  810  and the back portion  812  define a neck opening  818  defined by a back collar edge  824  along the back portion  812  and a front collar edge  822  along the front portion  810 , a torso opening  820 , a first armhole opening  830   a , and a second armhole opening  830   b . As shown, the upper panel  808  of the upper-body garment  800  comprises an upper perimeter edge  814  and the lower panel  806  comprises a lower perimeter edge  816 . The lower perimeter edge  816  and the upper perimeter edge  814  are overlapped with each other in a closed state of the upper-body garment  800 . In example aspects, the lower perimeter edge  816  may be positioned external to the upper perimeter edge  814 . In other aspects, the lower perimeter edge  816  may be positioned internal to the upper perimeter edge  814 . The upper perimeter edge  814  and the lower perimeter edge  816  are substantially detached from each other and define a nursing opening  840 , which will be more apparent with respect to  FIG. 10 . As can be seen, the nursing opening  840  is located a predefined distance below the front collar edge  822  defining the neck opening  818  (e.g., within from about 10 cm to about 20 cm of the neck opening  818 ) and above the torso opening  820 . Further, as shown in  FIG. 9 , the back portion  812 , in example aspects, may comprise a smaller surface area than the front portion  810 . This may be because the back portion  812  is formed from a pattern piece that is narrower in a width-wise direction than the pattern piece used to form the front portion  810 . This allows for the upper-body garment  800  to be roomier in the front than the back without the need for ruching, as is conventional in maternity wear. Similar to the multi-layer nursing bra  100 , the upper-body garment  800  may be comprised of elastically resilient textile materials. The elastically resilient textile materials forming the upper-body garment  800  may be similar or different to the textile materials used in the multi-layer nursing bra  100 , depending on the type of fit desired for the upper-body garment  800 . 
     As shown in  FIG. 10 , the upper-body garment  800  is in an open state, which is achieved by exerting an upward force on the upper perimeter edge  814  of the upper panel  808  and a downward force on the lower perimeter edge  816  of the lower panel  806 , to open the nursing opening  840  and form opening  1000 . 
       FIG. 11  shows a wearer  1110  wearing the multi-layer nursing bra  100  and the upper-body garment  800  as a nursing bra system  1100 , where the multi-layer nursing bra  100  is worn under the upper-body garment  800  and the upper-body garment  800  is layered on top of the multi-layer nursing bra  100 . In  FIG. 11 , both the multi-layer nursing bra  100  and the upper-body garment  800  are in a closed state. As shown, the nursing opening  840  of the upper-body garment  800  is configured to generally, radially align with the bust area of the wearer  1110 , which also coincides with the outer layer  106  overlapping the inner layer  104  of the front portion  102 , and more particularly the right edge  125  and the left edge  126  of the outer layer  106  overlapping the upper edge  112  of the inner layer  104 . 
       FIG. 12  depicts the nursing bra system  1100  in an open state to create opening  1210  when both the multi-layer nursing bra  100  and the upper-body garment  800  are transitioned to the open state. As described above, in order to transition from the closed state shown in  FIG. 11 , the wearer would first transition the nursing opening  840  of the upper-body garment  800  by exerting an upward force on the upper perimeter edge  814  and a downward force on the lower perimeter edge  816 . Then, once the multi-layer nursing bra  100  is exposed, the multi-layer nursing bra  100  is transitioned to the open state by exerting an upward force on one or both of the right edge  125  and the left edge  126  of the outer layer  106  (in  FIG. 12 , only the right edge  125  is transitioned to the open state). Then, once at least a portion of the upper edge  112  of the inner layer  104  is exposed, a downward force is exerted on the upper edge  112  to create opening  1210  that extends through both the upper-body garment  800  and the multi-layer nursing bra  100  to provide access to the nipple area of the wearer. Finally, to transition the nursing bra system  1100  back to its closed state, an upward force is exerted on the upper edge  112  of the inner layer  104  and a downward force is exerted on the respective right edge  125  and/or the left edge  126  of the outer layer  106  of the multi-layer nursing bra  100  followed by exerting an upward force on the lower perimeter edge  816  and a downward force on the upper perimeter edge  814  of the upper-body garment  800 . 
     Although the example upper-body garment  800  is shown as a tank top style garment, it is contemplated that many other types of garments may be provided with the nursing bra system  1100  in accordance with aspects herein. For example, as shown in  FIG. 13 , the upper-body garment may be a short sleeved shirt  1300  having nursing opening  1310 . In other instances, the upper-body garment may include a dress, shirt, sweater, sweatshirt, hoodie, blouse, and the like that are configured to cover an upper torso area of the wearer. Further, it is also contemplated that the multi-layer nursing bra  100  or the upper-body garment  800  may be worn on their own (i.e., independently of the multi-layer nursing bra  100 ), without departing from aspects herein. 
       FIG. 14  depicts a series of steps outlining a method  1400  for manufacturing a multi-layer nursing bra, such as the multi-layer nursing bra  100 , in accordance with aspects herein. As shown, at a first step  1410 , the method  1400  starts by forming a front portion of a multi-layer nursing bra by positioning an inner surface of an outer layer adjacent to an outer surface of an inner layer. Then, as shown at step  1420 , a lower edge of the inner layer is affixed to an underband, followed by affixing a lower central portion of the outer layer to a discrete area of the underband, as shown in step  1430 . It is contemplated that the order in which the steps are performed may be changed, meaning that the order is discretionary. As well, it is also contemplated that there may be additional steps performed in the manufacture of the multi-layer nursing bra in accordance with aspects herein. 
       FIG. 15  depicts a series of steps outlining a method  1500  for using a nursing bra system, such as the nursing bra system  1100 , in accordance with aspects herein. For instance, a wearer may don a multi-layer nursing bra (e.g., multi-layer nursing bra  100 , multi-layer nursing bra  400 , or multi-layer nursing bra  402 ) over an upper torso of the wearer, as shown at step  1510 . Step  1510  is followed by step  1520 , which includes donning an upper-body garment (e.g., upper-body garment  800  or  1300 ) over the multi-layer nursing bra such that a nursing opening of the upper-body garment is radially aligned with a front portion of the multi-layer nursing bra, where both the multi-layer nursing bra and the upper-body garment are in a closed state, as shown at step  1530 . When the wearer needs to feed or pump, the multi-layer nursing bra system is transitioned to an open state by first exerting an upward force on an upper perimeter edge defining the nursing opening of the upper-body garment and exerting a downward force on a lower perimeter edge defining the nursing opening of the upper-body garment to open the nursing opening and expose the front portion of the multi-layer nursing bra, as shown at step  1540 . This allows the wearer to exert an upward force on one or both of the right edge and/or the left edge of the outer layer to expose at least a portion of an upper edge of the inner layer forming the front portion of the multi-layer nursing bra, as shown at step  1550 . Next, a downward force is exerted on the upper edge of the inner layer to create an opening on the front portion of the multi-layer nursing bra to expose a nipple area of the wearer, as shown at step  1560 . Once the wearer has finished breast feeding or pumping, the wearer may first return the multi-layer nursing bra to the closed state by exerting an upward force on the upper edge of the inner layer and a downward force on one or both of the right edge and/or the left edge of the outer layer to close the opening on the front portion of the multi-layer nursing bra as shown at step  1570 . Finally, the wearer may also return the upper-body garment to the closed state by exerting an upward force on the lower perimeter edge defining the nursing opening and exerting a downward force on the upper perimeter edge defining the nursing opening of the upper-body garment, as shown at step  1580 . 
       FIG. 16  depicts a front view  16  of another example multi-layer nursing bra  1600  in a closed state, in accordance with aspects herein. When worn, the multi-layer nursing bra  1600  can also be in one of a closed state or an open state. As shown, the multi-layer nursing bra  1600  includes a front portion  1602  having an inner layer  1604  that may have a substantially upright “Y-shape” or a triangular shape with the base of the triangle positioned above the apex. The front portion  1602  also includes an outer layer formed from a right-side outer layer  1616  and a left-side outer layer  1618 . As shown, a medial portion  1622  of the right-side outer layer  1616  overlaps a medial portion  1620  of the left-side outer layer  1618  at a center area  1624  of the front portion  1602 . Moreover, the right-side outer layer  1616  and the left-side outer layer  1618  are overlying or are positioned adjacent to the inner layer  1604 , as will become more apparent with respect to  FIG. 18 , which shows a deconstructed view  18  of the front portion  1602  of the multi-layer nursing bra  1600 . As further shown in  FIG. 16 , a portion  1638  of the inner layer  1604  is not covered by the right-side outer layer  1616  or the left-side outer layer  1618  when the right-side outer layer  1616  and the left-side outer layer  1618  are layered on top of the inner layer  1604 . The multi-layer nursing bra  1600  may optionally comprise a pair of shoulder straps  1630   a  and  1630   b.    
     The inner layer  1604  of the multi-layer nursing bra  1600  has an upper edge  1808  extending between an upper right portion  1610  and an upper left portion  1614 , a right edge  1606  having a midpoint  1840  extending between the upper right portion  1610  and a lower central portion  1612 , and a left edge  1608  having a midpoint  1842  extending between the upper left portion  1614  and the lower central portion  1612 . In some aspects, the inner layer  1604  may be comprised of multiple layers of material, while in other aspects, the inner layer  1604  may be comprised of a single layer of material. The upper right portion  1610 , the lower central portion  1612 , and the upper left portion  1614  are positioned so that the inner layer  1604  forms a substantially upright “Y-shape.” In accordance with aspects herein, the right edge  1606 , the left edge  1608 , and/or the upper edge  1808  of the inner layer  1604  are curved inwardly with respect to a central area  1806  (shown in  FIG. 18 ) of the inner layer  1604  although the right edge  1606 , the left edge  1608 , and/or the upper edge  1808  may curve outwardly or be substantially straight. 
     The right-side outer layer  1616  has a right-side upper edge  1626 , a right-side lower edge, and a right-side edge  1636   a . The left-side outer layer  1618  has a left-side upper edge  1628 , a left-side lower edge, and a left-side edge  1636   b . The right-side upper edge  1626  and the left-side upper edge  1628  may be finished with a stretch seam such as a zig-zag stitch, a twin needle stitch, a chain stitch, flat lock stitch, cover stitch, overlock stitch (serge stitch), and the like. Alternatively, the right-side upper edge  1626  and the left-side upper edge  1628  may be finished off with a seam with a “hidden” stitch, which is a single, surged interlock stitch sewed while the bra is inside-out. When the bra is flipped right-side out, the stitching is hidden. In other words, the right-side upper edge  1626  and the left-side upper edge  1628  are free of stitching on an outer surface of the multi-layer nursing bra  1600 . This hidden stitch may provide for improved comfort and greater stretch along the right-side upper edge  1626  and the left-side upper edge  1628 , allowing the right-side outer layer  116  and/or the left-side outer layer  1618  to be pulled down easier for nursing and/or pumping (as shown in  FIG. 19 ). The right edge  1606  and the left edge  1608  of the inner layer  1604  are substantially detached from the right-side outer layer  1616  and the left-side outer layer  1618 . As shown in  FIG. 16 , when the multi-layer nursing bra  1600  is in a closed state, at least a portion of the right edge  1606  and at least a portion of the left edge  1608  of the inner layer  1604  are positioned below the right-side upper edge  1626  of the right-side outer layer  1616  and the left-side upper edge  1628  of the left-side outer layer  1618  (shown in dashed line to indicate it is generally hidden from view in the closed state). In other words, in the closed state, the right-side upper edge  1626  of the right-side outer layer  1616  and the left-side upper edge  1628  of the left-side outer layer  1618  are located above the right edge  1606  and the left edge  1608  of the inner layer  1604 . 
       FIG. 17  depicts lateral view  17 , where the shoulder strap  1630   a  in combination with the right-side edge  1636   a  of the right-side outer layer  1616 , and shoulder strap  1630   b  in combination with the left-side edge  1636   b  of the left-side outer layer  1618 , form in part arm openings  1634  through which the wearer may extend her arms when wearing the multi-layer nursing bra  1600 . Further, although the shoulder straps  1630   a  and  1630   b  are depicted as being in a crisscross configuration in the back of the multi-layer nursing bra  1600 , it is contemplated that the shoulder straps  1630   a  and  1630   b  may have other configurations such as parallel or T-shape. As well, the multi-layer nursing bra  1600  may comprise a strapless configuration, or a halter type configuration without departing from the aspects disclosed herein. 
     As shown in  FIG. 18 , the inner layer  1604  has a first or outer surface  1810  and a second or inner surface  1812  opposite the outer surface  1810 . Similarly, the right-side outer layer  1616  has a first or outer surface  1816  and a second or inner surface  1814  opposite the outer surface  1816 . As well, the left-side outer layer  1618  has a first or outer surface  1818  and a second or inner surface  1820 . The outer surface  1810  of the inner layer  1604  is positioned adjacent to the inner surface  1814  of the right-side outer layer  1616  and is further positioned adjacent to the inner surface  1820  of the left-side outer layer  1618 . 
       FIG. 18  also depicts an underband  1632  having an upper edge  1832  and a lower edge  1834 . Thus, when the multi-layer nursing bra  1600  is assembled, a right-side lower edge  1802  of the right-side outer layer  1616  and a left-side lower edge  1804  of the left-side outer layer  1618  are secured to the upper edge  1832  of the underband  1632  by sewing, bonding, or other affixing technologies. As well, the lower central portion  1612  of the inner layer  1604  is secured to a central portion  1830  of the underband  1632 . Further, the upper right portion  1610  of the inner layer  1604  is affixed to a portion of the right-side edge  1636   a  of the right-side outer layer  1616 , and the upper left portion  1614  of the inner layer  1604  is affixed to a portion of the left-side edge  1636   b  of the left-side outer layer  1618 . It is contemplated that the underband  1632  may extend at least along the right-side lower edge  1802  of the right-side outer layer  1616  and at least along the left-side lower edge  1804  of the left-side outer layer  1618  of the front portion  1602 . When the multi-layer nursing bra  1600  comprises a back portion or right and left wing bands, as described with respect to  FIG. 4A  and  FIG. 4B , the underband  1632  may extend from the lower edge of the back portion or the right and left wing bands. 
       FIG. 19  depicts a front view  19  of the multi-layer nursing bra  1600  in an open state. Although opening  1902  is only shown on the right side, both the right and the left sides can be transitioned to the open state at or near the same time, or one at a time, as shown. Initially, in order to open a right side of the multi-layer nursing bra  1600 , a downward force is exerted on at least a portion of the right-side upper edge  1626  of the right-side outer layer  1616 , thereby exposing at least the midpoint  1840  of the right edge  1606  of the inner layer  1604 . In other words, the right-side upper edge  1626  is pulled below at least the midpoint  1840  of the right edge  1606  of the inner layer  1604 . In example aspects, when the multi-layer nursing bra  1600  is worn, the right edge  1606  of the inner layer  1604  is positioned above the nipple area of a wearer. Once the right-side upper edge  1626  of the right-side outer layer  1616  is pulled downward, an opening  1902  is formed to provide access to the nipple area of the wearer for breast feeding or pumping. In other words, in the open state, at least a portion of the right-side upper edge  1626  of the right-side outer layer  1616  and/or the left-side upper edge  1628  of the left-side outer layer  1618  is located below the right edge  1606  and/or left edge  1608  of the inner layer  1604  to create the opening  1902 . Once the breast feeding or pumping is completed, the multi-layer nursing bra  1600  may be returned to the closed state by exerting an upward force on the right-side upper edge  1626  of the right-side outer layer  1616  to return the multi-layer nursing bra  1600  to its closed state, as shown in  FIG. 16 . This arrangement of multi-layer nursing bra  1600 , like the arrangement in the multi-layer nursing bra  100 , also provides several advantages by eliminating the need for hard-to-manipulate clasps, uncomfortable pressure points resulting from the clasps, and an ease of manipulation, particularly single-handed manipulation, and the like. 
     Similar to the multi-layer nursing bra  100 ,  400 , and  402  shown in  FIGS. 1-7 , the multi-layer nursing bra  1600  is also functional to be worn alone or as a system with the upper-body garment  800  or  1300 , as discussed above. For example, as shown in  FIGS. 20 and 21 , the upper-body garment  800  may be donned over the multi-layer nursing bra  1600  such that a wearer  2002  may wear the multi-layer nursing bra  1600  and the upper-body garment  800  as a nursing bra system  2000 . In  FIG. 20 , both the multi-layer nursing bra  1600  and the upper-body garment  800  are in a closed state. As shown, the nursing opening  840  of the upper-body garment  800  is configured to generally, radially align with the bust area of the wearer  2002 , which may also generally coincide with at least the midpoint  1840  of the right edge  1606  and the midpoint  1842  of the left edge  1608  of the inner layer  1604  of the front portion  1602 . 
       FIG. 21  depicts the nursing bra system  2000  in an open state to create opening  2100  when both the multi-layer nursing bra  1600  and the upper-body garment  800  are transitioned to the open state. As described above, in order to transition from the closed state shown in  FIG. 20 , the wearer would first transition the nursing opening  840  of the upper-body garment  800  by exerting an upward force on the upper perimeter edge  814  and a downward force on the lower perimeter edge  816 . Then, once the multi-layer nursing bra  1600  is exposed, the multi-layer nursing bra  1600  may also be transitioned to the open state by exerting a downward force on at least a portion of the right-side upper edge  1626  of the right-side outer layer  1616 , thereby exposing at least a portion of the right edge  1606  of the inner layer  1604  to create opening  2100  that extends through both the upper-body garment  800  and the multi-layer nursing bra  1600  to provide access to the nipple area of the wearer for breast feeding or pumping. More particularly, the opening  1000  radially aligns with the opening  1902  created between at least one of the right-side upper edge  1626  of the right-side outer layer  1616  or the left-side upper edge  1628  of the left-side outer layer  1618  and the right edge  1606  or the left edge  1608  of the inner layer  1604 . Although the multi-layer nursing bra  1600  is shown as being used with the upper-body garment  800 , it is also contemplated that the multi-layer nursing bra  1600  may also be used with an upper-body garment having a stretchable neckline that may be pulled down to expose the multi-layer nursing bra  1600  for nursing and/or pumping. 
     Once the breast feeding or pumping is completed, to transition the nursing bra system  2000  back to its closed state, an upward force is exerted on the right-side upper edge  1626  of the right-side outer layer  1616  to return the multi-layer nursing bra  1600  to its closed state, followed by exerting an upward force on the lower perimeter edge  816  and a downward force on the upper perimeter edge  814  of the upper-body garment  800 . 
       FIG. 22  depicts a series of steps outlining a method  2200  for using a nursing bra system, such as the nursing bra system  2000 , in accordance with aspects herein. For instance, a wearer dons a multi-layer nursing bra (e.g., multi-layer nursing bra  1600 ) over an upper torso of the wearer, as shown at step  2210 . Step  2210  is followed by step  2220 , which includes donning an upper-body garment (e.g., upper-body garment  800  or  1300 ) over the multi-layer nursing bra such that a nursing opening of the upper-body garment is radially aligned with a front portion of the multi-layer nursing bra, where both the multi-layer nursing bra and the upper-body garment are in a closed state, as shown at step  2230 . When the wearer needs to feed or pump, the multi-layer nursing bra system may be transitioned to an open state by first exerting an upward force on an upper perimeter edge defining the nursing opening of the upper-body garment and exerting a downward force on a lower perimeter edge defining the nursing opening of the upper-body garment to open the nursing opening and expose the front portion of the multi-layer nursing bra, as shown at step  2240 . This allows the wearer to exert a downward force on one or both of a right-side upper edge of the right-side outer layer and/or a left-side upper edge of the left-side outer layer to expose a nipple area of the wearer, as shown at step  2250 . Once the wearer has finished breast feeding or pumping, the wearer may first return the multi-layer nursing bra to the closed state by exerting an upward force on one or both of the right-side upper edge and/or the left-side upper edge the upper edge as shown at step  2260 . Finally, the wearer may also return the upper-body garment to the closed state by exerting an upward force on the lower perimeter edge defining the nursing opening and exerting a downward force on the upper perimeter edge defining the nursing opening of the upper-body garment, as shown at step  2270 .
