Right Fit. First Time.
We know finding the right size sports bra and supportive swimwear can be tough – Women's bodies are regularly changing.
We designed the Spirit High Impact Aquatic Sports Bra and Spark High Impact One Piece to be super adjustable so they'll suit a variety of body types, different stages of life, and any time of the month.
Even so... We recommend taking your measurements before you purchase to get the right fit, first time.
If your size is not available, please know we’re working on it! Our priority is expanding our sizing.
MEASURING YOUR BODY
1) Over bust
Wrap the tape around the fullest part of your bust – usually best to do this with a bra on and remember to keep the tape straight and untwisted.
2) Under bust
Wrap the tape around your body directly under the bust (might help if you’ve got a bosom buddy to give you a hand).
Keep the tape as straight as possible and, if you’re wearing a bra, make sure it’s not sitting over the band or underwire.
3) Waist
Measure around the narrowest part of the torso, keeping the tape straight.
4) Hips
Measure around the fullest part of the hips, again, keep that tape straight.
When in doubt, check out sizing grid below or on each of the product pages.

JOI products are made with a high level compression fabric (65% Nylon Recycled 35% Xtra Life LYCRA®) which means the fit is snug. If you are unsure, we recommend going up a size.
You've taken your measurements, made your purchase and still not completely feeling the JOI. No worries, we'll gladly refund or exchange all qualifying orders.
