17 Legitimately Scary Halloween Costumes That'll Give Your Friends Nightmares

Warning: Minor spoilers ahead.

Some people like wearing sexy or cute costumes to Halloween, which is perfectly fine. But if you're serious about Halloween, you've got to try wearing an actual scary costume at least once in your life. Which is why we've compiled this list of scary Halloween costumes for adults, straight from some of the most iconic horror movies in history.

17 Scary Halloween Costumes for Adults
1. Valak from Hereditary

The Hereditary franchise has really milked it with its sequels and spinoffs. The most recent, The Nun, centres on that horrific nun figure Valak, and though we've been seeing images of the ghastly ghoul everywhere, the terror hasn't gotten old.

The best part of this costume is how quickly you can whip it up, provided you're extra resourceful. All you need for this costume is a long black dress or graduation gown, a nun habit, (learn how to improvise one here), a rosary, and serious makeup skillz.

2. Slender Man

Very few creepypasta memes make it to the mainstream, and Slender Man even made it to the big screen with a 2018 horror movie. Slender Man is usually depicted as thin, unnaturally tall humanoid with no face, and he typically wears a black suit.

So to create a Slender Man costume, you can simply wear a black suit with a white morph mask and gloves. But if you're feeling extra, you can order drywall stilts from Lazada or Shopee and sew on extra fabric onto your suit, as seen above.

3. Annabelle

Another scary figure from the Hereditary franchise, Annabelle has become one of the most recognisable figures from modern horror. And it's not a complicated costume either — all you'll need is an old-fashioned white dress, red ribbon for the belt, a wig, and creepy makeup. It's all in the contouring!

4. The twins from The Shining

If you've ever wanted to try twinning with your BFF but never seem to get round to it, now's your chance. The creepy twins from The Shining, you'll need two of everything: blue dresses, pairs of knee-length socks, wigs and hair clips, and black ballet flats. Practice saying "come and play with us" in unison and stand in hallways to make the experience complete.

5. The Purge

 Since the first movie in 2013, people have loved dressing up as the franchise's masked murderers. All you need is an eerily smiling mask and you're done!

6. Pennywise the Clown

 It basically ruined clowns for generations of children (and adults), and Pennywise is so creepy that you're bound to scare more than a few people when you go out partying on Halloween night. Plus it's an excuse to bring around a helium balloon!

7. The Other Mother from Coraline

Another costume that requires quite a bit of makeup skill, the Other Mother's clothes aren't hard to find: either a beige cable-knit turtleneck sweater or a black and white polka-dotted top, plus a wig. There are several makeup tutorials out there on this look, so if you're not confident about your skills, get practicing.

8. Regan from The Exorcist

The Exorcist will forever and ever be terrifying, and frankly, even looking at the cosplay above is giving me the heebie-jeebies. But this is pretty easy to execute: all you need for this costume is a white nightgown and some face paint (prosthetics if you're really committing to it). Yoga skills optional.

9. Sadako from The Ring

 If you've got extra long hair, going as Sadako (or Samara) from The Ring will be a breeze, but it's pretty easy to buy the right wig for this online. Bonus points if you lug around a hollowed out television to climb out of.

10. Chucky

 Chucky gave us nightmares as kids, and now it's our turn to pay it forward and terrify trick-or-treaters with our take on the living doll.

11. Pinhead from Hellraiser

This might be one of the more complicated scary Halloween costumes for adults on this list, but the effort is well worth it. Pinhead, the leader of sadomasochistic creatures from the Hellraiser franchise, is one of the most iconic horror movie villains in history, but with a costume this elaborate, you'll impress not just the horror movie buffs.

12.Freddy Krueger

No self-respecting scary Halloween costumes for adults list will be complete without Freddy Krueger from Nightmare on Elm Street. Sure, you can just easily a Freddy Krueger rubber mask from the toy store and call it a day, but what's the fun in that?

Here's another costume that you can whip up in just a day. All you need is an old gown that you never plan on wearing again, a blonde wig (optional), a tiara, and fake blood (get some red poster paint, mix with water, and you're done).

14. Ghostface from Scream

Who doesn't know this mask from the 90s slasher franchise Scream? It's super easy to find the mask, which makes this one of the easiest costumes to pull off on this list. And the best part is you don't have to worry about your makeup all night!

15. Jason from Friday the 13th

Here's a recipe for one of the most popular scary Halloween costumes for adults: Hockey mask? Check. Dirtied up flannel shirt and jeans? Check. Now all you need is a toy chainsaw and you're good to go.

Pay tribute to one of the most iconic horror movie villains in history with an orange jumpsuit, a mask, and a crazed look in your eye.

17. Charlie from Hereditary

Though this costume might not look scary to anyone who hasn't watched Hereditary, anyone who was messed up by the movie will get the shivers from just a headless figure in an orange hoodie. To make your costume complete, just click your tongue.
