Using this Vivian floral strapless bikini top is super easy. Just slip it on like you would any regular tube top. It's a great piece for a day at the beach or a pool party. When it comes to fit, as the style runs true to size, pick your normal size. If you're in between sizes, you might want to go a size up for more comfort. As for maintenance, after each use, rinse it in cool water to get rid of salt, sand, or chlorine. Don't wring it out; instead, gently squeeze the excess water. Hang it to dry in a shaded area, away from direct sunlight to prevent color fading. Also, avoid using harsh detergents as they can damage the fabric. With proper care, your bikini top will stay in great shape for many swims to come.
