How to use this Gruffalo costume is super easy. Just put on the brown all - in - one jumpsuit and pull the hood over your head. Make sure the Velcro closure is fastened properly so it stays on during the party or event. When it comes to safety, always keep the costume away from fire as the dyes used might not be colourfast. As for maintenance, don't throw it in the washing machine. Instead, use a sponge to clean it when it gets dirty. This way, your Gruffalo costume will stay in great shape and can be worn again and again for more fun occasions.
