My daughter is 14yrs old she is having heavy breast and with sagging may be it weighs 1kg ... Day by day her breasts are increasing in size. While she is sitting the breast is sagging and falling on stomach. She can't stand straight because of heavy breast she need to bind a little... While she is skipping or running or dancing she is getting short breathe because of heavy breast If I choose any big size bra for my daughter then after 2weeks it is getting more tight
