Brighten up everyone's Halloween this year with our Men's The Addams Family Uncle Fester Adult Costume. Uncle Fester is quite possibly the most eccentric out of the whole Addams family clan. Though he is a member of the gang, Fester often keeps to himself to entertain his hobbies, like putting his head in a screwpress or feeding his plants blood plasma. The costume includes a floor-length, hooded robe with belt rope and a mask in typical pasty, sunken-eyed Uncle Fester form. Don't forget to bring a lightbulb with you when you're embodying this bald-headed weirdo, another one of Fester's favorite activities is using his mouth to turn on lightbulbs. Don't fret about purchasing a costume that looks a little dead, he may be a bit of an oddball, but Uncle Fester is full of life and is sure to be a crowd pleaser.
