Im 15 and I've been wearing a bra ever since i can remember. No one really told me how to use one, so i used it all day and night. It wassn't till i was older that i found out people dont usually wear it to sleep. Its become such a habit its hard to stop. Clothes just feel so uncomfortable without it. ANyway, I havn't developed breasts yet i wonder if wearing a bra all the time will stop them from growing. And Is it normal to sleep with one all the time?
