How big is a size 32A bra?

Not VERY big, but average for maybe a 11-14 year old.

Um actually to the first answer......it depends on your body frame and it can be an average size for a petite WOMAN. I am actually a 28 B, 30a, 32AA Yes they are all the same size Bras! Depends on the make and manufacturer. They are just numbers so who cares. Should be happy with what ya have. Everyone is different
