To use this bikini bottom, simply put it on and adjust the side ties to your desired tightness. When swimming, it'll stay in place and give you a great look. Remember, since it has a skimpy design, be careful when doing very active water sports to avoid any unexpected slipping. After use, rinse it with fresh water to get rid of salt and sand. Don't wring it out too hard; just gently squeeze the water out. Hang it to dry in a shaded area, not in direct sunlight, as that can fade the black color and damage the fabric. And when you're packing it for your next trip, fold it neatly to keep its shape.
