Women Sizes
No method of measuring guarantees a perfect fit for everyone the first time. The chart below is a guide to give you a place to begin.
- Measure rib cage (under breasts). This is your bra size (32, 34, etc.). Round up to even numbers.
- Measure fullest part of bust (best with a bra on).

If the above method yields a result which is much different from what you are used to, order what makes sense to you. We recommend ordering either your current size or a size between what you wear and what you measure.
Sometimes ordering two different sizes can help you get the right fit more quickly, knowing that one or both can be exchanged or refunded if returned in their original condition. See our return policy.
A fitting guide is included with each purchase to help you fine-tune your fit.
Girl Sizes
Girl sizes are based on rib measurement and age. For many, size runs true to age (i.e. 8 year olds wear size 8). Just as with adults, no one measurement guarantees a perfect fit the first time. The chart at right is a good place to start.
