You can call your girlfriend and ask for her bra size. If you aren't comfortable asking her, then buy her something that is not a bra.
small
There is no ideal bra size for a 12 year old. Your bra size will change a lot over the next 8 years, and probably over your entire life.
Emma's bra size is 34A. (info from the Ballet Shoes film set) But it this way Im a 30A im 34C Yes you should be proud of your size, I am 28-30a ish

Umm.. you dont ?
If you like to wear bras, you should wear a bra. If there is some reason that you don't think you should (such as if your mom says you're too young or you're a boy who knows it's socially unpopular), then balance other people's opinions with your feelings. It might be worth not wearing a bra for awhile, or it might be a better choice to wear the bra anyway.
Usually, this is not a bad thing. But try wearing a sports bra, it makes the chest area look smaller. Never not wear a bra because that's not very safe :P Hope i helped
