To use these Amarilla bikini bottoms, simply tie the side strings to your desired tightness. They're great for swimming, sunbathing, or any beach activity. When it comes to maintenance, rinse them with fresh water after each use in saltwater or chlorinated water. Then, lay them flat to dry in the shade, as direct sunlight might fade the check print. Since this is a final sale item, please choose your size carefully. Avoid rough handling to keep the gold bead detailing intact.
