I had to google AA breasts, yeah, they are small, but unless you're already well into your 20s, there's a chance you're gonna put on more weight, get bigger boobies etc. as you get older and it's not worth worrying about tbh. Also if you're very short they're gonna look more in proportion with your body, hence not so small. A 6ft tall women with 32AAs...yeah that would be wrong.
