These 10 Plus Size Halloween Costume Ideas Are So Scary, They Deserve a Horror Movie
As someone who has spent years helping people put together Halloween looks that turn heads, I’ve learned this: scary doesn’t mean sacrificing style. And plus size? That’s not a limitation—it’s a superpower. One of my favorite parts about Halloween is seeing how people turn everyday items and iconic characters into terrifying (and fabulous) ensembles that could easily belong in a horror movie. But if you’re curvy, it can sometimes feel like all the good costumes weren’t made with you in mind.
That’s why I wrote this post—for every plus-size babe who wants to be scary, fierce, and totally unforgettable this Halloween. These aren’t your basic cat or witch costumes (although, we love a classic). These are bold, spooky, and scream-worthy plus size Halloween costume ideas scary enough to cause a scene—in the best way.
Let’s dive into 10 killer ideas that will make you the star of any spooky celebration.

1. Gothic Medusa Queen
Imagine walking into a party and everyone goes quiet—not because you’re late, but because you’re terrifyingly stunning. That’s the Medusa effect. Swap the typical glam goddess version for a darker twist: black and gold snakes, a structured black corset, and eerie green eye makeup. Throw on gold cuffs and a crown of snakes for an unforgettable myth-meets-nightmare vibe.
Pro tip: Use a body-hugging black dress or tunic underneath and layer with accessories. This is a great option if you want a costume that’s DIY and also work-party friendly with some modifications.
2. Evil Little Red Riding Hood
We all know Little Red Riding Hood—but what about the version that ate the wolf? This twist on the fairy tale uses familiar elements—a red cape, a basket, a flirty dress—but with a horror twist. Add some ripped tights, fake blood, and a sneer, and you’re no damsel in distress.
This costume is perfect for last minute prep because most pieces are already in your closet. It also works well with a black corset and a simple red cloak—which brings us to our first product recommendation!
Amazon Pick #1: Red Hooded Cape Cloak with Velvet Finish
Why I Love It: This full-length velvet red cape instantly elevates your costume. It drapes beautifully over any body type and gives a luxurious, spooky touch.
Perfect For: Little Red Riding Hood, vampires, witches, or devilish queens.
Grab this dramatic red cloak on Amazon before it sells out—it’s a Halloween staple you’ll reuse every year.
3. Sinister Clown from the Carnival of Nightmares
Clowns have always been creepy, but a blood-spattered plus size clown with sharp-toothed makeup and twisted pigtails? That’s horror movie material. You can go full Pennywise or mix in your own color palette (try black, red, and white for a bold contrast). Add oversized bows and striped socks for a cute but creepy edge.
Don’t forget—this can also double as a funny costume if you lean into exaggerated clown antics.
4. Undead Cleopatra
I once did this costume with a friend for a couple’s party—I was Cleopatra, and she was my mummy servant. We shredded gold fabric, smeared eyeliner, and walked in like ancient royalty back from the grave.
To pull this off, start with a flowy gold or white dress and layer bandage strips or gauze. Smudge your iconic eyeliner and tease your hair for that I-just-crawled-out-of-a-tomb look.
Pair it with someone as a cursed Pharaoh for a creepy couple costume idea.
5. Drowned Sea Witch Mermaid
Mermaids aren’t always sweet—they can be monsters too. This is one of the most unique plus size Halloween costume ideas scary enough to haunt your dreams. Use a shimmering skirt or fishtail, torn tulle, and create a ghostly ocean queen vibe with dripping pearls and dramatic blue lipstick.
Optional Add-On: Add creepy seaweed (green netting works well!) and a statement corset to tie the whole look together.
Amazon Pick #2: Plus Size Faux Leather Pleated High Waist Maxi Mermaid Skirt
Why I Love It: This stretchy, body-hugging skirt has a fishtail hem and real mermaid magic. It hugs your curves in the best way and looks killer with a black corset or bralette.
Perfect For: Mermaid, sea witch, or drowned siren looks.
Snag this mermaid skirt on Amazon and build your creepy sea creature costume from the fins up.
6. Possessed Disney Princess
If you’ve ever wanted to take a sweet fairytale and flip it on its head, this is your moment. Take any Disney princess (Cinderella, Ariel, Snow White) and zombify her. Add pale makeup, dripping mascara, ripped dresses, and a glass slipper covered in.
This is the ultimate mix of disney, cute, scary, and even last minute.
7. Haunted Woodland Deer Spirit
One year, I helped my cousin create this look for a school party—it was adorable and eerie at the same time. Think soft brown tones, black nose makeup, twigs in your hair as antlers, and cracked face makeup.
If you want something cute, DIY, and easy, this is a magical pick. It’s also one of the more office-appropriate or work-friendly looks if you tone down the spook factor.
8. Scary Witch in a Black Corset
Nothing screams Halloween like a witch—but this one isn’t your green-faced storybook kind. This is the dark queen of the forest, with lace gloves, jagged nails, and a cinched waist that commands the room.
Pair your black corset with a tulle skirt or pants, layer necklaces, and go all out with eye makeup. This look is easy, sexy, scary, and empowering.
Amazon Pick #3: Plus Size Black Corset with Steel Boning
Why I Love It: This corset is supportive, adjustable, and surprisingly comfy. Whether you're a witch, vampire, or Medusa, it adds that structured wow factor.
Perfect For: Witch, Medusa, Little Red, pirate, or any villainous character.
Shop this black corset on Amazon and let your inner dark queen rise this Halloween.
9. Ghost Bride from the Underworld
Thrifted wedding dress? Check. Black roses? Check. Tattered veil and vacant stare? You’ve got a show-stopping ghost bride look. This idea is super DIY-friendly, cost-effective, and scary as hell.
You can keep it soft and spectral or go full gothic nightmare—just don’t forget the smoky eye and fake blood.
10. Possessed Office Worker
If you need something for a work party but still want to scare your coworkers (nicely), this is it. Wear your regular office attire—button-down shirt, pencil skirt—but make it look like you’ve been dragged through the 7th circle of hell.
Rips, soot, blood-splatter, and an ID badge that says “DEMON INTERN” seals the deal. This idea is funny, easy, and office-appropriate with a spooky twist.
Bonus Tips to Slay Halloween as a Plus Size Ghoul
- Go bold with silhouettes: Don’t shy away from form-fitting dresses, corsets, or crop tops. Halloween is about character, not covering up.
- DIY saves the day: Some of the best looks I’ve seen were made from thrifted or everyday pieces. Pinterest and TikTok are treasure troves of tutorials.
- Comfort matters: You’ll be walking, dancing, or at least standing around in your costume, so make sure it moves with you.
- Confidence is the magic spell. No matter what you wear, the way you wear it makes the costume. Own it.
Couple Costume Ideas That Are Equally Terrifying
If you want to double the screams, here are a few couple costume ideas that match the scary vibes:
- Medusa + Stone Statue – She turns him to stone. Literal couple goals.
- Zombie Ariel + Pirate Prince Eric – Your favorite Disney pair, post-apocalypse.
- Haunted Red Riding Hood + Werewolf – Bloody but make it romantic.
- Dead Bride + Corpse Groom – Tim Burton would approve.
Where to Show Off These Scary Costumes
Whether you’re heading to a haunted house, a neighborhood block party, or just trick-or-treating with friends, here are a few places to let your horror-flick look shine:
- Halloween office parties (go for deer, office zombie, or ghost bride)
- Costume contests (the scarier, the better!)
