Using this 1920s bathing suit costume is a breeze. First, put on the one - piece jumpsuit. Use the velcro at the back to close it up. Then, place the straw hat on your head. Stick the self - adhesive moustache on your upper lip for that perfect 1920s look. Remember, this is a costume, not a real swimsuit, so don't wear it for swimming. When it comes to maintenance, take it to a dry cleaner as it can only be dry - cleaned. Since it's an adult - sized costume, keep it away from children. Also, because the dyes may not be colorfast, avoid contact with water that could cause the colors to run. And always keep it far from fire to ensure safety.
