To wear this Pikachu costume, simply step into the jumpsuit and pull it up over your body. Then put the hood on your head, making sure the structured ears are in place. When playing around, be careful not to catch the tail on anything. After use, you can machine - wash it on a gentle cycle with cold water. Hang it to dry to keep the shape and color of the costume. This costume is designed for kids aged 7 - 8, so make sure it fits well before wearing.
