How to use this fireman costume is super easy. First, put on the trousers and then slip into the jacket. Don't forget to place the fireman's helmet on your head to complete the look. When it comes to safety, this is an adult - only costume, so keep it away from children. The dyes might not hold their colour well, so be careful when it's around things that could get stained. And most importantly, since it's a costume, always keep it far from fire. For maintenance, you can't just throw it in the washing machine. Take it to a professional dry - cleaner to keep it looking its best.
