When wearing this red prom dress, simply slip it on and adjust the halter neckline for a comfortable fit. Make sure to check the size chart to get the right fit or use our free custom - sizing option. As for maintenance, since it's made of chiffon, it's best to hand - wash it in cold water with a gentle detergent. Avoid wringing it out to prevent damage to the fabric. Hang it to dry and store it in a cool, dry place. When you're not wearing it, keep it on a hanger to maintain its shape.
