Here's how to understand bra sizing:
* Band Size (the number): This refers to the measurement around your ribcage directly under your bust. A 34 band is larger than a 32 band.
* Cup Size (the letter): This refers to the difference between your ribcage measurement and your fullest bust measurement. A B cup is one size larger than an A cup.
Therefore, a 34B has a larger band size *and* a larger cup volume than a 32A.
