Our swimwear does run compressional but that is completely intentional. It is meant to hug you and really form as a second skin, especially while wet when most fabric tends to stretch out and lose its shape. 

Generally, if you are in between sizes, we recommend sizing up in swimwear. However, sizing is also dependent on personal preference. If you are in between sizes and want more coverage size up, if you want less coverage size down.

Email us at hello@geminimountainswimwear.com with any questions and we'd be happy to help recommend your size.

* Note: bamboo loungewear pieces have a lot more stretch than our swimwear so we recommend sizing down in bamboo if in between sizes. If you have a larger cup but a smaller band just make a comment in the notes section at checkout and we can adjust the band size for you.
