As well as an undergarment, the bra is considered a foundation garment 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 standard method for supporting a woman's breasts.
The bra may be worn to support and enhance breast shape during everyday activities. A specialized bra, the sports bra, can be worn to support and restrain breasts during exercise. The bra may also be worn to preserve modesty or to present a certain image of femininity. Bras are typically designed to lift the breasts into a particular position, for a more youthful look or for enhancing cleavage.
These roles are sometimes conflicting. Some designers aim at producing a garment that fulfills a practical role as well as making it look attractive. Bras are also used during pregnancy (when breasts are enlarged and more sensitive), and for nursing to support and provide access for breast feeding.
