To wear your Lumia triangle bikini top, simply adjust the over - the - shoulder straps to your preferred tightness. Tie the back tie securely to keep the top in place. When choosing a size, refer to the size chart as this style runs true to size. For maintenance, hand - wash the bikini top in cold water with mild detergent. Avoid using bleach or harsh chemicals as they can damage the SoftSwim fabric. After washing, gently squeeze out the water and lay it flat to dry. Don't wring it to prevent the fabric from losing its shape. Store it in a cool, dry place when not in use.
