Question: what are bra sizes a b c d?
Answer: The letters - like A, B, C, D - stand for cup sizes. The numbers - like 32, 34, 36, 38 – tell you the band size – that's the part of the bra that goes around your torso. In other words, a 34A means that your boobs are an A cup and that your bra is 34 inches around.
