Average bra size

Answer 1

Average American female bra size is 34B. Average European female size is 34C!

Seeing as most women are wearing the wrong size bra, normally because they are measured in the old fashioned way, most women are wearing bra with bigger band sizes than what they need and smaller cup size than ideal. Recent research and theory suggests that the average size for women is around 34DD (rather than 36B as some have claimed). This reply isn't much different to the one above but it's something interesting to note. The average is harder to determine as 8/10 women are wearing the wrong size. lol
