What does ABCD stand for in bra size?

The letters in your bra size correspond to the difference between your bust measurement and band measurement. For example, if you measure 36 inches around the fullest part of your chest, and 34 inches around your band, you'd have a difference of 2 inches, which corresponds to a B cup.

Use this chart to help determine your cup size.
