Ghostbusters
Who you gonna call? The iconic ghoul-fighting gang of the '80s, the Ghostbusters make for the perfect spooky squad costume for you and your bros! And ladies, with the femme reboot coming up soon, you and your girls shouldn't be afraid to bust some ghost ass either.
What to wear: Hazmat suits, rubber gloves, chunky boots, backpacks equipped with ghost-sucking Proton Pack!
