Using the Katarina bikini bottom is a breeze. Just slip it on like you would any other swimwear. When you're at the beach or pool, adjust it to your comfort. Make sure to rinse it with fresh water after each use to get rid of salt, sand, or chlorine. Avoid wringing it out too hard as it might damage the fabric. For storage, hang it up in a cool, dry place. Don't expose it to direct sunlight for a long time as it can fade the true red color. Also, don't use harsh detergents when washing it; a mild soap is best.
