You can go to the mall or a shop and go yo the bra side with who ever you went with and try to find out what size you are or go to a bra place and have someone mesure you to get the right fitting bra
Bra sizes have nothing to do with waist size. A slim girl can have a large bra size or a small one. It just depends on her DNA.
There is no "normal" bra size. It varies from girl to girl.
The biggest bra size that us girls can have so far is 38kkk
Ask her ;)
Your only option is to guess the girl's bra size. If you are not buying her a bra, you don't need to know her bra size. Try to find out something that's important to her instead.

Actually there is no bra which comes in normal size. All bras are made for a particular shape and size. Bra size always depends on your body shape, bust size and band size. Every woman has their unique shape and size and they also have their own comfortability of bra. Two women with the same size can not feel comfortable in the same size bra because they may have the different bust shape for which bra size and style varies.
I am a 16 year old girl and I wear the bra size 34AA and when I was 13 my breasts did not even start growing and I did not have a training bra when I was 13. You should talk to your mom or a doctor cause your bra size is not normal for your age.
Age does not determine breast size. Any size is normal.
It is absolutely normal but each person is different and not all teenagers know how to check the bra size correctly. You can discover much more about breast development, bra size and bra styles in the link below.
