Our suits run pretty true to size as per our size charts. Our suits are designed for comfort and being active, both in and out of the water. They are made with 100% recycled materials and double-lined for durability, so our fabric won’t stretch out as much as other swimwear you might be used to. This means that if you are on the cusp between two sizes, we would recommend sizing up, as our fit may feel more snug. We recommend measuring yourself following the guidelines provided on our size chart page. Please note, some of our styles do differ and have a unique fit. So in addition to using our size charts, we recommend also referring to any specific recommendations provided on each product page.
