Our bikinis are super cheeky. Your suit should be snug, secure & tight when you first try it on so that once it's wet, you achieve a perfect active water fit. We sew very skimpy so just because the size is L, that doesn't mean more coverage. Our swimwear will keep a consistent minimal cut, no matter the style/size.
