To wear this Dennis The Menace kids' costume, simply put it on like you would any regular outfit. Before putting it on, make sure it's the right size from the UK sizing chart. When you're out having fun as the troublemaker, be careful not to get it dirty too quickly. After use, remove any debris gently. You can machine - wash it on a gentle cycle with similar colors to keep it looking great. Store it in a cool, dry place to prevent any damage.
