To use this dress, simply slip it on over your swimwear or other outfits. It's perfect for a day at the beach or a casual outing. When it comes to maintenance, you can hand - wash it in cold water with mild detergent. Avoid using bleach as it may damage the fabric. After washing, lay it flat to dry. If it gets wrinkled, you can gently iron it on a low - heat setting. Keep it in a cool, dry place when not in use to maintain its quality.
