1. Measure Band Size. Take a snug measurement around your rib cage, below your bust and shoulder blades. Then add 4 inches. If you get an odd number (like 35), round up one (to 36).

2. Measure Cup Size. With bra on and clothes off, measure around the fullest part of your bust.

3. Compare bust measurement to band measurement. Subtract the band measurement (Step 1) from the bust measurement (Step 2). Then use the charts below to determine your cup size.
