Ever Had Your Boobs Sized?
Also of note is the fact that the larger the band size, the larger the cup size gets, regardless of whether or not it's labeled A, B, C. So a bra that is a 42C is going to have cups that are incrementally bigger than a bra that is a 34C. Make sense? The numbers provide a good general guide, but...when it really comes down to it, all the brands are soooo different. Two people's C-sized breasts are probably wildly different sizes in reality.

Proud 32C btw.
Ike me who spends so much time looking at boobs
