brassiere

n. woman's undergarment designed to support the breasts

A brassiere (Brit. ; U.S. , commonly referred to as a bra, ) is an article of clothing that covers, supports, and elevates the breasts. The bra is considered a foundation garment, as well as an undergarment, because of its role in shaping the wearer's figure. It was originally developed in the late nineteenth and early twentieth centuries to replace the corset, and has now become, in many parts of the world, the most popular form of undergarment for the upper body, although camisoles and chemises are becoming more popular.
