Band
Size:
Measure directly under your breasts (rib cage) with
bra on. Then add 3 inches. This is your band size. If it is an odd
number such as 41, go up one number so your band size would be 42.
Cup Size: Measure around the fullest part of your
breasts. If it is 3 inches larger than you band size, you are a
C cup, 4 inches more is a D cup and 5 inches more is a DD cup.
