Do i need a bra? Please Help!!?

Most likely you're an A cup or smaller. You probably don't need a bra, but I know some kids around your age start wearing training bras. If you're able to go shopping on your own yet go to somewhere like Primark or another cheapy clothing store and find an A cup bra to try on. If your breasts fill it out then you may need one, but to be honest it's not likely. And they certainly won't bounce, not at your age. You may want to ask your mum for some, just to get used to it. I know it's embarassing, but you have to do it at some point...
