Its is adcisable for girls with a larger cup size to wear coz it
might injure your back too.. and your breasts will sag... when u
age..unless those small cup size like kate moss then its fine.
Anyway a bra is design primarily to support your breasts then to
cover it up. But go braless when u at home to let blood circulate.
Nowadays in this modern society, its acceptable for girls to go
braless but please dun wear white when going braless.
