To use this set, simply put on the babydoll top and then the matching thong. It's perfect for a romantic night in. When it comes to maintenance, it's best to hand - wash this set in cold water with a mild detergent. Avoid using bleach or harsh chemicals as they can damage the delicate mesh and crochet. After washing, gently squeeze out the water and lay it flat to dry. Don't wring it to prevent stretching. Also, keep it away from sharp objects to avoid snags.
