In women's clothing, a corselet or corselette is a type of foundation garment, sharing elements of both bras and girdles. It extends from straps over the shoulders down the torso, and stops around the top of the legs. It may incorporate lace in front or in back. As an undergarment, a corselet can be open-style (with suspenders attached) or panty-style.
Historically, the term referred to a piece of plate armour covering the torso.
