Using this Suki bikini bottom is a breeze. Just slip it on and adjust the elasticated edges for a perfect fit. When you're out by the pool or at the beach, it'll keep you comfortable all day. For sizing, remember if you're in between sizes, go up a size. After each use, rinse it with fresh water to remove any salt, sand, or chlorine. Don't wring it out too hard as it can damage the elastic. Let it air dry in a shaded area. Avoid using harsh detergents as they can harm the 80% nylon and 20% spandex fabric. With proper care, your Suki bikini bottom will stay in great shape for many swims to come.
