what is sheath silhouette
Definition of a Sheath Dress. Definition: A sheath dress features a silhouette that fits close to the body, and can have a hemline that hits anywhere from mid-thigh to mid-calf. A sheath by definition (think about the sheath of a sword, for example) is meant to hold close to that which it encases. The neckline can vary, but a fitted waist is the focal point of this type of dress.
