Scare the life out of your roommates without even trying! In this DIY Chucky costume, all you need is a striped long-sleeve top, some overalls, and a little face makeup to give off those stitched-up, possessed doll vibes.

I think this DIY is genius if you love a deep cut that comic book fans will appreciate.
5. DIY Willy Wonka Look That’s Cooler Than the Golden Ticket
