To use this bikini top, first adjust the shoulder straps to your desired length. Then, put it on like a regular bra, making sure the underwire is properly positioned under your bust. Tie the back ties to secure it in place. You can adjust the tightness of the back ties for a more comfortable fit. When it comes to maintenance, it's best to hand - wash the bikini top in cold water with a mild detergent. Avoid using bleach or harsh chemicals as they can damage the fabric. After washing, gently squeeze out the excess water and lay it flat to dry. Don't wring it out as it may cause the fabric to stretch. Also, keep it away from direct sunlight when drying to prevent color fading. If you're not using it, store it in a cool, dry place, preferably in a fabric storage bag to protect it from dust and scratches.
