To use this Merino bikini, simply put it on like any other swimsuit. It's great for lounging around at home or wearing during your outdoor adventures. When it comes to care, it's best to hand - wash it in cool water with a mild detergent. Avoid using bleach or harsh chemicals as they can damage the Merino fabric. After washing, gently squeeze out the excess water and lay it flat to dry. Don't wring it or hang it up as this may cause it to stretch. Also, store it in a cool, dry place when not in use to keep it in good condition.
