To wear this lingerie gown set, simply put on the gown first and then the matching thong. You can wear it for a special night or just for your own comfort. When it comes to cleaning, it's best to hand - wash it in cold water with mild detergent. Avoid using bleach or harsh chemicals as they can damage the lace and satin. After washing, gently squeeze out the water and lay it flat to dry. Don't wring it or hang it up wet, as this may cause the fabric to stretch. Keep it in a cool, dry place away from direct sunlight to maintain its color and quality.
