Pennywise: My parents only let me read a little of the book IT but here's my interpretation of Pennywise!!! You will need: A fake arm, fake blood on one end (George Denbrough) A normal clown outfit, but not too "happy". A balloon A black permanent marker Makeup Put on the clown outfit Take the marker and write "I Y DERRY!" on it. Paint scars and stuff on your face. Carry the arm around while trick-or-treating, and voila! Thanks to Emily for this good idea Another Idea From the movie: Pennywise has an all wite face, a black rimmed mouth with red lips and red hair only on the right and left sides. He also has a clown suit with blood and claw hands. Thanks to Moco for this addition. Clown Around Town Child Costume Includes: Hat, jacket with attached shirt front, bow tie and pants. Wig, nose, gloves, lollipop and shoes not included.
