A bra, short for brassiere or brassière (US: /brəˈzɪər/, UK: /ˈbræsɪər/ or /ˈbræzɪər/; French: [bʁasjɛʁ]), is a form-fitting undergarment that is primarily used to support and cover breasts. It can serve a range of other practical and aesthetic purposes, including enhancing or reducing the appearance of breast size and creating cleavage. Bras can also serve specific functions, such as nursing bras to facilitate breastfeeding or sports bras to minimize discomfort during exercise.
