What is Bra?

The female breasts have very little internal support, being composed largely of adipose tissue. It is believed that the primary anatomical support for the breast is provided by the Cooper's ligaments, with the skin covering the breasts offering some additional support. However, this anatomical support is usually insufficient to hold the breasts up (especially in older women), and to prevent movement of the breasts, which can cause pain and discomfort. The primary reason for wearing a brassiere or similar foundation garment is thus to provide external support for the breasts, both to increase comfort and to provide a sexually alluring figure.

Bras are believed by some to help preserve the youthful shape of breasts (which naturally sag as women grow older), an opinion which is unsurprisingly promoted by bra manufacturers. However, there is some doubt over this amongst the medical community, and while a woman may choose to wear a bra for comfort or for social reasons, there is no conclusive evidence to support the notion that a woman's breasts will sag lower over her lifetime if she doesn't wear a bra.

Some medical professionals believe that wearing a bra can actually increase breast sagging later in life because the chest muscles that support breasts are used less and atrophy from lack of use. Health benefits of breast motion and sagging have also been suggested but not substantiated — for example, some researchers claim that breast movement, which is restricted by a brassiere, stimulates the lymphatic system and helps remove toxins from the body
