How to Determine your Bra Size?

Measure Band Size and Cup Size
To determine your bra size (and to find the perfect fitting bra), it is very important that you measure your body carefully. You need to measure both bust size (over bust) and band size (under bust). See illustration above, and read our measuring instructions below:

1. Measure Under Bust (Band): Measure circumference around your body just under your bust/breasts. Make sure to keep the measuring tape parallel with the ground. Use your measurement to determine your band size from the Band Size Chart below.

2. Measure Over Bust: Wear a non-padded bra (or no bra) while measuring. Stand with your arms at your side (ask a friend for measuring help if possible). Measure circumference around your body (under arms) at the fullest part of your bust. Make sure the measuring tape is parallel with the ground, and not binding. Use both Over Bust Measurement and Under bust Measurement to determine your Cup Size from the Cup Size Chart below.

3. Determine Band Size and Cup Size: Now you are ready to determine your band size and your cup size. Use your measurements to determine sizes from the size charts below.
