To wear this Bad Dad Costume, first put on the all - in - one racing driver style jumpsuit. Make sure it fits you well. Then, put on the black eyemask to complete the look. When you're done having fun in the costume, remember to sponge clean it only. Don't machine wash or dry clean it, as this may damage the embroidery and the fabric. Keep the costume in a cool, dry place when not in use to prevent it from getting dirty or damaged. Enjoy your time in this super - fun costume inspired by David Walliams' books!
