You're a mean one, mister, but that doesn't faze you considering that Christmas is your least favorite holiday. The Santa Grinch with Mask Adult Costume comes with a realistic-looking Grinch mask, a Santa suit, a matching Santa hat, and a pair of green hands. The costume is worn like a tunic and features white trim along the cuffs and the hem. The mask is designed to have a devious grin, and the gloves are covered in a faux fur material that is thoroughly creepy, so this costume could even be worn during Halloween. The Grinch stole Christmas, and if your hate for the holiday rivals this Dr. Seuss character's, then go ahead and do the same. Add a pair of green stockings and other accessories from the website to enhance this costume.
