CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims the benefit of U.S. Provisional Patent Application No. 62/022,204, filed on Jul. 9, 2014, and incorporated herein by reference. 
     
    
     STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH AND DEVELOPMENT 
       [0002]    Not Applicable. 
       FIELD OF THE INVENTION 
       [0003]    The present invention relates generally to a shirt stay, and more particularly, to a device having a plurality of straps and clips for maintaining formal attire. 
       DISCUSSION OF RELATED ART 
       [0004]    A shirt stay can generally be described as a device which discretely prevents a shirt from untucking during the course of the day. Shirt stays are commonly used with military and law enforcement uniforms, where the appearance of a squarely tucked and fitted wrinkle free shirt is paramount. Furthermore, military appearance is a characteristic trait that is observed, graded and considered during promotion reviews in all services. Accordingly, use of shirt stays to enhance one&#39;s appearance has become increasingly popular. 
         [0005]    Current shirt stays comprise one or a plurality of elastic straps that connect to the socks or feet on one end and the shirt on the other. Here, the tension between the feet or socks and the shirt will prevent the shirt from untucking and will prevent any wrinkles from displaying, as the shirt is held taught. Other methods of keeping a shirt tucked in include rubber belts, molded hooks, or suspenders. 
         [0006]    While several methods for preventing a shirt from untucking exist in the prior art, they are generally uncomfortable, easily unfasten, difficult to attach and/or remove, require a specific order when attaching, unduly burdensome on the feet and legs, or are simply ineffective. Furthermore, the most common types of shirt stays typically pull on leg hair as they become taught and cause the pants behind the knee to project outward when kneeling or sitting. Therefore, a need exists for a device which is comfortable to wear for extended periods of time, can quickly and easily attach and detach from the shirt in any order, is effective at preventing a shirt from becoming untucked, does not pull on leg hair, provides knee support, and will not project the pants behind the knee outward when kneeling or sitting. The present invention satisfies these needs. 
       SUMMARY OF THE INVENTION  
       [0007]    The present invention provides a device which is comfortable to wear for extended periods of time, can quickly and easily attach and detach from the shirt in any order, is effective at preventing a shirt from becoming untucked, does not pull on leg hair, provides knee support, and will not project the pants behind the knee outward when kneeling or sitting. As such, the present invention serves to keep formal attire tucked and taught, promoting an all-day impeccable professional appearance without undue burden or discomfort. 
         [0008]    The above objectives are accomplished through a knee strap, one or a plurality of elastic bands, and one or a plurality of shirt attachment clamps. The knee strap will attach to the leg below the knee, the plurality of shirt attachment clamps will securely attach to the shirt, and the elastic bands will connect them together. When in use, the present invention will be attached or detached below the pants, and as such, will be concealed from view. Lastly, the present invention will be adjustable for all different body types. 
         [0009]    These and other objectives of the present invention will become obvious to those of ordinary skill in the art after reading the following detailed description of the preferred embodiments. It is to be understood that the foregoing general description and the following detailed description are exemplary, and are intended to provide further explanation of the invention as claimed.

         [0032]    The plurality of elastic bands  20  each comprise a proximal  21  and distal  22  end. Each distal end  22  comprises a female pivoting attachment means  23  adapted to pivot with the attachment means  14  of the knee strap  10 . In the preferred embodiment, the female attachment means  23  is a female button snap adapted to pivotally attach to said male button snap. Just as the male attachment means  14 , the female attachment means  23  provides a pivoting point for the present invention such that, when sitting, the present invention does not protrude the pants  50  in the area behind the knee. 
         [0033]    Each of said plurality of elastic bands  20  further comprises a first elastic band  24  and a second elastic band  25 . The first and second elastic bands  24 ,  25 , inherently, each have a proximal  21  and distal  22  end. The first and second elastic bands  24 ,  25  are each attached to said female attachment means  23  at their distal ends, forming a generally V-shape. The first and second elastic bands  24 ,  25  are made of a hypoallergenic material that is comfortable, durable, generally elastic, and easily laundered. 
         [0034]    Said first and second elastic bands  24 ,  25  further comprise a band length adjustment means  26  to adapt to each individual user. In the preferred embodiment, the band length adjustment means  26  is an adjustable ring, slide, hook, buckle, clasp, clamp, or other adjustable means. The band length adjustment means  26  may be incorporated with said female attachment means  23  such that band length adjustment means  26  will adjust the length of said first and second bands  24 ,  25  about said female attachment means  23 . The first and second elastic bands  24 ,  25  are made of a hypoallergenic material that is comfortable, durable, easily laundered, and elastic to further accommodate fit, comfort, and prevent undesirable rubbing or chafing. 
         [0035]    A plurality of shirt attachment clamps  30  are attached at each proximal end  21  of said first and second elastic bands  24 ,  25 . Each shirt attachment clamp  30  is adapted to securely attach to the bottom of a shirt  40  such that the connection will not unintentionally become undone during the course of the day.
