How to Measure
1. Bust
Measure around the fullest part of your bust while wearing an unpadded bra. Note this number.
2. Underbust/Band
Next, measure under your breasts, around your ribcage, then add 3 to this number. For example, if you measure a 31" ribcage, your band size is 34. If the number is an odd number, round up to the next even number.
3. Cup Size
Lastly, take your bust measurement minus your band measurement to determine your cup size using the chart below. For example, if your bust is 38" and your band measurement is 34", your bra size is a 34D.
