Brassiere
A brassiere 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.
The bra may be worn to support and to restrain pendulous breasts during exercise (especially the sports bra) or to support and enhance their shape during everyday activities. Many wearers also wear bras in the questionable belief that it will prevent their breasts from sagging later in life. In the scientific medical literature 
there are no reports that support the notion that wearing a bra will prevent sagging of breasts. Some reports have suggested that wearing a bra will promote ligament atrophy, which contributes to sagging. The bra may also be worn to observe modesty or to present a certain image of femininity. Bras are typically designed to lift the breasts from their normal position, for a more youthful look or for enhancing cleavage . These roles are sometimes conflicting. Designers usually aim at producing a garment that fulfills a practical role as well as making it look attractive. Reportedly, bras are particularly important during pregnancy (when breasts are enlarged and more sensitive), and for nursing (see nursing bra) to accommodate breastfeeding.
Many have questioned the practical need for the bra. Many women prefer not to wear a bra and 
go braless on a regular basis. In many nations, a bra is often not worn. Some have suggested that a bra does little to prevent the effects of aging on the breasts, and some have claimed that breasts are healthier when left free to move rather than being restrained. Also, the bra has become charged with political and cultural meanings that overlay its practical purpose. Traditionally it is viewed as symbolic of a young girl's coming of age, one of the tokens that indicate that she has become a young woman. It can also be interpreted as a feminine icon. On the other hand, some may see it as a symbol of the repression of women's bodies. All of these debates mean that the bra has assumed a cultural significance which far outweighs that which is normally accorded to an item of clothing
