To use this bikini bottom, simply put it on and adjust the side ties to your desired tightness. When you're at the beach or pool, enjoy the freedom and style it offers. As for maintenance, after each use, rinse it in fresh water to remove salt, sand, or chlorine. Avoid using harsh detergents. Let it air - dry away from direct sunlight. Store it in a cool, dry place. If you need to adjust the size later, you can easily do so with the adjustable side ties. Also, make sure to check the fit before you head out to the water to ensure a comfortable and secure wear.
