To use this costume, first help your child put on the white jacket with the gold buttons. Then, let them step into the trousers. Finally, place the hat with the small peak on their head. It's perfect for a kids' birthday party or any fancy - dress event. When it comes to safety, make sure children under 3 years don't use it because of the small parts that could cause a choking hazard. Keep the costume away from fire. As for maintenance, remember that you can only dry clean it. Don't try to wash it at home to avoid any damage to the fabric or the buttons.
