Note: Our bikinis and swimsuits are intentionally designed to be on the smaller side, as they are functional and made for surfing. This is because the fabric stretches when wet. If an Oy product feels a little tight when you try it on dry, that's intentional. If the functional aspect of our products isn't important to you, then you can try a size larger than normal.
