A slightly padded bra will avoid this problem. Best wishes:)
You should definatly wear a bra I mean I'm the same age as you and I wear a bra I'm only a 30A
Tell your mom that you can see your breasts through your shirts and you need a bra. Until you go shopping wear a tank or a cami under everything you wear until you buy some.
If you don't wear a bra, you can put band-aids over your nipples....also if you go to Wal-Mart in the lingerie section they have nipple petals that you can buy....but band-aids are much cheaper =)
Well, when you go shopping, you should go in to a store that definitley sells bras, like limited too or macy's, and say, hey, can I get one, or I just won't fit, and if you're to embarrassed to say it in front of the person, go with someone who you're not embarrassed in front of. That's what I did. I'm almost 13,( in December) and I'm a 34a.
I think you should,just to avoid the pointed nipples thing.You shouldn't get a bra that is tight thou coz you are still so young and your lady lumps still need to grow.
Go get a bra. After you get used to the idea of having boobs, you might want to try going without a bra. I'm a 32 B and I only wear a bra for work.
