How to use: First, put on the zip-up jumpsuit. It's easy to wear with the zip feature. Then, fasten the harness around your body to add that authentic firefighter look. Finally, place the helmet on your head securely. Note: Make sure to check the size guide before buying to get the right fit. Also, since it's imported, the sizing might be a bit different from local standards. Maintenance: This costume is delicate, so always hand wash it. Avoid using harsh detergents as they can damage the fabric. After washing, let it drip dry naturally. Don't wring it or put it in a dryer to keep it in good condition for a long time.
