Have a fear of clowns? They're usually pretty creepy anyway, but if you're indeed frightened by them there's some chance that it all started because of Pennywise the Clown. He's one of the scariest clowns around! Our Pennywise Halloween costumes let you become the terrifying character. We don't recommend hanging out in the sewers in this thing, but there's no doubt it will inspire more than a few screams this Halloween.
