Calculate Your Size

How to Measure

Step 1: Band / Underbust
Wrap the measuring tape snugly around your ribcage, just under your bust. Keep the tape level all the way around. Round to the nearest whole number. If even, that is your band size. If odd, add 1.
Step 2: Bust
Wrap the tape around the fullest part of your bust. Keep the tape level and do not pull too tight. Round to the nearest whole number.
Step 3: Cup Size
Subtract the band measurement from the bust measurement. Each inch of difference equals one cup size (1"=A, 2"=B, 3"=C, etc.).
