Thank you for viewing! Both items are amphibious, but I have never used them underwater; I have worn them as yoga wear. Please note that the sizes are different for the top and bottom. The top is size S, and the bottom is size M. Please purchase only if you can accept that they have been stored at home. We will compress them when shipping, so wrinkles or crushing of the cups may occur. We are very sorry, but we do not negotiate prices, so please understand.
