To use this bikini bottom, simply put it on like you would any regular swimwear. When choosing a size, refer to the size chart as it runs true to size. Before your first use, it's a good idea to rinse it in fresh water. When you're done at the beach or pool, rinse it again to remove salt, sand, or chlorine. Hang it to dry in a shaded area to prevent the color from fading. Avoid using harsh detergents or bleach when washing. For best results, hand - wash it in cool water and gently squeeze out the excess water. Store it in a cool, dry place, and it will stay in great shape for many beach days to come.
