So unless you're already going as Rust Cohle from True Detective, any character from Frozen, or the Joker for the 6th year in a row (i.e., something really cool and original), we have the perfect idea for your Halloween costume this year. It's really simple. Plus, it's free.
Just download this cut out Halloween mask. Use scissors, an X-Acto knife, or anything with a sharp blade to actually cut the mask out. And then fasten it to your face. Voila! You're golden.
Limited to however many people download it.
