What is a "sheath"?

A sheath is a fitted, body-hugging dress with a simple, straight cut. It is usually designed to be sleeveless with a hemline that falls above the knee or below the calf. The dress is typically made of stretchy or clingy fabric that contours the body, providing a flattering and feminine silhouette. The simplicity of the design and the clean lines make it a versatile dress that can be dressed up or down depending on the occasion. It is often worn to work, as well as to more formal events such as weddings and cocktail parties.
