To use this Naia bikini bottom, simply put it on like you would any other swim bottom. Adjust the side ties to your desired tightness for a perfect fit. When you're at the beach or pool, enjoy the flattering look it gives you. As for maintenance, after each use, rinse it in cool water to remove salt, sand, or chlorine. Avoid using harsh detergents as they can damage the fabric. Hang it to dry in a shaded area. Don't wring it out too hard to prevent stretching. If you're not using it for a long time, store it in a cool, dry place. And remember, always pair it with the matching Naia bikini top for a complete and stylish look.
