How Is A Bra Size Calculated?

The first number in a bra size indicates the measurement around your chest just under your bust. So size 32C means that the bra is 32 inches around the chest. The letter after the number is the cup size. The cup size is the distance around the fullest point of your bust. To measure this yourself you can wear an unpadded bra, make sure you keep the measure straight and not too taught. A is the smallest cup size and it can go all the way up to H and more.

At some high street fashion stores you can get your bra size measured for free.
