A brassiere ( UK: /ˈbræzɪər/ or US: /brəˈzɪər/), commonly referred to as a bra /ˈbrɑː/, is a woman's undergarment that supports her breasts. Bras are typically form-fitting and perform a variety of functions and have also evolved into a fashion item. The primary purpose of a bra is to support the woman's breasts. In western cultures, about 10–25% of women do not wear a bra, either as a matter of preference or sometimes for health or comfort reasons. Some garments, such as camisoles, tank tops and backless dresses, have built-in breast support, alleviating the need to wear a separate bra. Changing social trends and novel materials have increased the variety of available designs, and allowed manufacturers to make bras that in some instances are more fashionable than functional. Bras are a complex garment made of many parts, and manufacturers' standards and sizes vary widely worldwide, making it difficult for women to find a bra that fits them correctly. Even methods of bra-measurement vary, such that even professional fitters can disagree on the correct size for the same woman. As a result, 75–85% of women wear a bra of an incorrect size. The bra has become a feminine icon or symbol with cultural significance beyond its primary function of supporting breasts. Some feminists consider the brassiere a symbol of the repression of women's bodies.
