Why do girls have to wear bra's?

Answer 1

Girls should wear a bra to support their breasts. As they are developing and especially after they develop, the breasts should be developed. It can hurt to run and have them bounce, so many girls prefer a sports bra when doing physical activites. Also, it helps to keep them supported and padded so that they are less sore and don't get bruised. Breasts are sensitive and, like any other muscle, can bruise or get sore very easily. A bra helps create a nicer shape under clothes, as well as makes it more comfortable to wear clothes and to move about during the day, too. Many girls feel more comfortable in public knowing they have the support and coverage of a bra.
