Cup size: The difference in inches between the bust measurement and the band size.

Each inch of difference corresponds roughly to a cup size letter:

1 inch = A cup
2 inches = B cup
3 inches = C cup, etc.

Cup size is relative to band size. For example, a 34B and a 38B have the same cup letter but different volumes because the band sizes differ. This means a 38B cup is larger in volume than a 34B cup.

3″	C
4″	D
