35 Seriously Scary Costumes to Haunt Your Halloween

The movie Terrifier and its sequel are verifiable word-of-mouth hits, but you'll be sure to terrify people in this costume even if no one had ever heard of Art the Clown — its vibe is just too creepy. This costume comes with the clown outfit and the teeth, so you have to do your own scary makeup.

If you're looking to turn your dress-up event into a date night, try the coordinating zombie patient and zombie nurse couples' costume. For a more youthful twist on the idea, you can also try the zombie football player and zombie cheerleader costumes, but the nurse is scarier in our opinion.

Sometimes, it's what you don't see that is the scariest. This costume comes with a black full-body suit and light-up glasses, so you can be the glowing eyes in the night.

Why is this jack o'lantern smiling? For no good reason, we can tell you that! This costume comes with the tunic, collar, belt and mask — you just need to add the wig.

No one would want to be trapped overnight with this alive animatronic demon! This is the titular Freddy Fazbear, but there are also kids' costumes for Foxy, Chica and Bonnie, all of whom are equally creepy.

The best part about this costume is getting to come up with the ghost bride's backstory. Was she jilted on her wedding day? Expired before she could walk down the aisle? You get to decide. This costume comes with the dress and veil.

Step right up for the scariest show on Earth! This costume comes with the mask, jacket, vest, tie and top hat, but you have to bring your own sense of showmanship. You can also get a skeleton ringmistress costume to go with it if you want to make it a double act.

No one will be able to look you in the (milky white) eyes when you're wearing this flexible demon mask. (Be warned, though: Amazon reviewers say it can be hard to see through.)

There are plenty of clowns on this list, and each one earns its place in a different way. This costume is inflatable, and its outsize proportions just serve to make it all the more unsettling.

The princesses may be the fairest ones of all, but Maleficent cuts the most striking figure, especially with those horns. The costume comes with the shawl and the horns, all you need is a black dress, black lipstick and a scowl.

This costume pulls off a neat trick: Since the shoulders and neck are fake, and worn over your own head, it makes it look like you have your own face in your hands. Who needs a headless horseman when you have this?

You don't have to have seen The Purge to find these light-up masks unsettling. They come in several colors, but be warned: The laws do still apply while you're wearing them.
