To use this Lumia bikini top, simply put it on like a regular bralette and adjust the shoulder straps to your desired tightness. Make sure the top fits snugly but not too tight to ensure comfort. When you're done swimming, rinse it with fresh water to remove salt, sand, or chlorine. It's best to hang it dry in a shaded area, as direct sunlight might fade the color. Avoid using harsh detergents when washing, as they can damage the fabric. With proper care, your Lumia bikini top will last you many swim seasons.
