A demon costume is one of the easiest Halloween looks to pull from your own closet, because the dress does most of the work and a pair of horns tells everyone the rest. I've styled it in velvet, lace, sequins and plain knit, and the version that reads best is always the one where the dress, the face and the headpiece share one color story. Below you'll find thirty dresses that run from classic red velvet and gothic lace to icy blue, moss green, pastel pink and starry navy, plus last-minute, plus-size, maternity, modest and DIY versions. None of them lean on gore. The drama comes from color, shape and horns that actually stay on your head.
Horns That Stay Put Through a Whole Party
Horns are the one piece that turns a dress into a demon, and they're also the piece that fails first. Most store-bought horn headbands are a thin plastic band with horns glued on top, so they slide back the moment you laugh. Before one goes on anyone's head, I fix it like this.
- Wrap the band in a strip of felt or ribbon with a dab of glue at each end. A soft surface grips hair far better than bare plastic.
- Slide a bobby pin through each side of the band into the hair underneath. On fine hair, cross two pins in an X just behind each horn.
- Check the joint where each horn meets the band. Hot glue turns brittle in cold air, so for an outdoor night I add a few stitches of thread or a wrap of floral wire around the base and cover it with ribbon.
- Match the horn size to the hairstyle. Big horns on a sleek bun tip forward, while loose waves cushion the band and hold it steadier.
If you wear glasses or have a sensitive scalp, wear the headband around the house for half an hour first. Pressure behind the ears builds slowly and tends to show up as a headache by the second hour of a party, which is far easier to fix at home with a wider band or a little padding.
1. Red Velvet Demon Dress Costume
Red velvet is the version I'd hand someone who has never worn a costume before, because nobody needs a second look to know what you are. Velvet already has depth under party lights, so I keep the extras sparse: a slim black belt, opaque black tights, curved black horns and a red tail that unclips when you sit. Brush the pile in one direction before you leave, since crushed patches show up as pale streaks in photos. Red lipstick with a softly smoked eye is plenty. For an outdoor party, a black capelet covers the shoulders without hiding the dress, and black ankle boots keep you steady.
2. Black Lace Demon Dress Costume
Lace is where I go for a gothic demon at a dressier party. The first thing I check is the lining, because unlined lace over bare skin looks unfinished under a camera flash, so look for a lined midi with lace sleeves and a high neck. Matte red horns stand out sharply against all that black, and burgundy ankle boots repeat the red at the hem. Plum lipstick, charcoal shadow and a thin line of red liner keep the face in the same family. Lace already carries a lot of pattern, so a velvet choker, a light black cape and a folding fan are all I'd add.
3. Fire Ombre Demon Dress Costume
An ombre that runs from black through red and orange into gold reads as flame from across a room, and chiffon helps because it moves every time you take a step. Ready-made ombre dresses rarely have the colors in the right order, so my usual shortcut is orange and red tulle layered under a plain black dress, with the bright layers peeking out at the hem. Paint the horn tips gold to echo the top of the gradient, and keep the shadow copper and burgundy so the face follows the dress. Clip-in red and orange extensions in a high ponytail carry the color up. The only light source I'd carry is a battery-powered glowing orb; chiffon and tulle catch fire fast, so candles and lanterns with real flames stay well away.
4. Ice Blue Demon Dress Costume
Ice blue is the demon for someone who wants to be asked what they are, in a good way. Pale satin shows every wrinkle, so I steam it on the hanger the night before instead of packing it folded. Frosted white horns, silver boots, translucent blue tights and a silver-gray wig keep everything cold-toned, and a single warm accessory breaks the effect, so carry a clear acrylic orb rather than anything black. A sheer silver cape adds coverage without hiding the color. Silver liner and small crystal gems at the temples need bright light to show, which is why this one is happiest at a well-lit indoor party.
5. Green Forest Demon Dress Costume
The forest version is the most fun to make, because the horns become the craft project. I start with plain brown branch-shaped horns and glue artificial moss and small leaves onto them, then tug every piece before it goes near anyone's hair. Real foliage dries and sheds within hours, so keep it artificial, and if the party is outdoors, add a few stitches or a twist of floral wire, because hot glue lets go in cold air. Underneath, a moss-green velvet maxi with a brown belt, dark green tights and lace-up boots. Green ribbon woven through loose braids, olive shadow with a touch of gold on the cheekbones, a short leaf-trimmed cape and a little wicker lantern finish it.
6. Purple Royal Demon Dress Costume
Purple pushes the demon toward royalty, and the crown is what sells it. A lightweight black crown sitting between polished purple horns gives a tall outline, but two separate headpieces means double the weight fighting for one spot, so I glue the crown and horns onto the same wide headband and they move as one piece. Under it goes a plum gown with puffed sleeves and a fitted bodice, black tights and pointed ankle boots with a stable heel. Metallic purple shadow and plum lipstick tie the face to the fabric. A jeweled collar and velvet cape bring enough drama. Carry a small decorative orb, not a scepter you'll have to set down every time you want a drink.
7. White Fantasy Demon Dress Costume
White is the surprise at a party full of red devils. A white maxi with bell sleeves or layered chiffon, a silver waist chain and white ankle boots keep it bright, while pale gray horns, a slim silver tail and translucent wings bring in the fantasy. The catch with white is makeup transfer: foundation and red lipstick mark it the moment they touch, so set your face with powder and drape a thin scarf over it while the dress goes over your head. Pearl shadow and gray liner keep the face soft. Temporary silver shimmer on natural hair works if you'd rather skip a wig, though it travels onto the dress, so brush out the loose excess before you get dressed.
8. Pink Cute Demon Dress Costume
Pink takes the menace out and leaves the fun. A bubblegum skater dress moves well, and white tights with pink platform sneakers mean you can dance all night. Small glittered horns, tiny wings and a pointed tail are enough to say demon; go any bigger and it drifts into fairy territory. Loose glitter migrates onto everyone you hug, so I look for horns where the glitter is sealed under a clear coat. High pigtails, heart face gems and a star-topped wand keep it playful, and a cropped faux-fur jacket covers you on the walk home.
9. Gold Glam Demon Dress Costume
A gold sequin dress is the dressiest demon here. Sequins scratch, especially at the underarm and inner elbow, so have whoever is wearing it sit and move in it for twenty minutes at home first; a soft slip underneath solves most of it. Matte black tights and black block-heel boots calm the shine, and gold horns with black bases match the dress without competing. Bronze shadow, sharp black liner and a deep neutral lip are all the face needs. A sheer black cape gives the gold real contrast, and a small structured clutch holds your phone.
10. Silver Futuristic Demon Dress Costume
Silver turns the demon modern rather than gothic. Smooth chrome horns and a structured shoulder cape create an angular outline over a metallic silver mini or midi with opaque gray tights, and white sneakers sit just as well in this palette as platform boots if you'll be standing for hours. The mistake I'd steer you away from is mixing metals. Gold earrings on a silver look read as an accident, so keep to silver, gray and white with one small black detail. A clear orb lit with battery fairy lights gives a safe glow, and mirrored cuffs pick it up at the wrists.
11. Victorian Gothic Demon Dress Costume
A high-necked Victorian dress gives more coverage and warmth than anything else on this list, which makes it my pick for a cold night. Look for black with a fitted bodice, long lace sleeves and a full ankle-length skirt, then add a burgundy petticoat so a flash of red shows when you walk. Don't size the bodice down for drama; you'll want to eat and sit. Lace-up boots, a cameo and black horns wrapped in red ribbon keep the period feel. Matte foundation with burgundy lips and precise liner suit the era better than shimmer, and a short velvet cape with a hand fan finishes it.
12. Medieval Demon Queen Dress Costume
The demon queen starts with a long burgundy or black medieval-style gown with bell sleeves and a lace-up neckline, which gives you the shape without a corset. Bell sleeves drag through every plate at a buffet, so I pin them back at the wrist with a small safety pin when it's time to eat. For the head, tall curved horns plus a crown cut from craft foam keep it regal without weight; thin foam softens under a hair dryer and curves neatly around a headband. A braided crown or long dark waves hide the band. Flat boots under the hem, a wide belt with decorative chains carrying a small pouch, a velvet shoulder cape and a jeweled orb are the rest. Leave heavy props at home.
13. Winged Fairy Demon Dress Costume
Fairy and demon blend well, as long as the wings stay small. A layered black and purple tulle dress with a fitted top and knee-length skirt gives the fairy half, and black horns trimmed with tiny flowers give the demon half. Measure the wingspan before you go: anything wider than your shoulders catches in doorways and on other guests. Lilac and charcoal shadow, star gems and berry lips match the tulle. Patterned tights, flat lace-up boots, a velvet choker and a small flower-covered lantern cover everything else.
14. Dragon Demon Dress Costume
This one is all about texture. A dark red or emerald wrap dress over a scale-pattern mesh top gives you scales without painting them on, and ridged horns, a flexible tail and small fabric wings in the same color tie it together. I'd keep every accessory foam or fabric, because a rigid tail knocks drinks off tables the first time you turn around. A long braided ponytail stays clear of the wings. For scales on the face, hold a piece of fishnet tights against the cheekbone and dab metallic green or copper shadow through it. Knee-high boots with a low heel and textured cuffs finish the look.
15. Raven Demon Dress Costume
Feathers shed. That's the first thing to know about a raven demon, and it's why I put feathers on a removable collar and a capelet trim instead of gluing them all over the dress. Start with a simple long-sleeved black midi, black tights and sturdy ankle boots. Small curved horns tucked behind a black braided headband look as if they're growing out of the hair. Charcoal shadow, a sharp wing and dark berry lips give the bird its edge, and a few black gems near the eyes hint at feathers. Synthetic feathers hold up better than real ones; trim any loose quill ends before you leave.
16. Moth Wing Demon Dress Costume
The moth demon is the softest look on the list and the easiest to thrift, since taupe and dusty brown dresses fill every secondhand rack. A draped-sleeve maxi in that range, dark brown tights and low lace-up boots make the base. The broad fabric wings in cream, gray and rust are the statement, and I attach them angled slightly behind the body, because wings that stick straight out get bent within the first hour. Short curled horns and an antenna headband share one band. Smoky brown shadow with tiny symmetrical dots at the temples echoes wing markings, while a faux-fur collar and copper jewelry add the fuzz.
17. Spiderweb Demon Dress Costume
A web-print dress does the Halloween work so the face doesn't have to. If you can't find one printed, ribbon webbing pinned onto a plain black skater dress comes off afterward and leaves the dress wearable. Silver tights, black ankle boots with a grippy sole, smooth black horns, a narrow tail and a web-shaped shoulder cape finish the outline. Wear the hair up so the pattern at the neckline stays visible. Silver shadow, black liner and a few crystals at the outer corners of the eyes keep it graphic. Snip any loose strings, since stretchy fake webbing snags on furniture and other people's costumes.
18. Orange Halloween Demon Dress Costume
Orange says Halloween before anyone even notices the horns. A rust-orange sweater dress is my favorite base here because a thermal layer fits underneath and nobody can tell, which matters on a cold doorstep. Black tights, black combat boots and a wide belt give it shape, and black horns with orange tips plus a light tail cover the demon part. Copper shadow, crisp liner and a muted berry lip suit the warm color. A black capelet scattered with small orange stars and a little pumpkin bag for your phone are the only extras I'd bother with.
19. Moon Demon Dress Costume
Navy or black scattered with silver stars gives the demon a night-sky theme. Removable appliqués on a plain maxi let you wear the dress again later. Iron-on stars are permanent and tend to lift at the edges on stretchy fabric, so I stitch or pin them instead. Black horns tipped with small silver crescents, a sheer midnight-blue cape and silver ankle boots keep the palette tight, with navy and silver shadow, tiny star gems at the temples and a plum lip. Keep the cape above the ankle so you don't step on it on stairs, and carry a moon-shaped bag that actually holds your keys.
20. Starry Navy Demon Dress Costume
Navy velvet keeps the drama of black but looks softer in person and far less flat in photos. A fit-and-flare navy midi with long sleeves, silver tights and dark blue boots is the base. Rhinestone stars on lightweight navy horns make the headpiece, and I use jewelry glue for those, because hot glue pops smooth rhinestones off as soon as the band flexes. A matching fabric tail and a high braided ponytail threaded with silver ribbon carry the color through. Midnight-blue shadow, silver liner and a cluster of tiny stars on one cheekbone are enough sparkle. For a long party, a structured navy bag beats a novelty prop.
21. Red Sequin Demon Dress Costume
Red sequins carry this whole costume, so everything else should go quiet. A knee-length wrap or long-sleeved mini with a proper lining, opaque black tights and cushioned black boots keep it wearable. Simple black horns, a slim tail and a short cape are plenty against all that sparkle. On the face, a black wing, bronze shadow and red lipstick; I skip heavy highlighter, because sequins already bounce light onto your skin. Run your fingers around the armholes and neckline before you buy, since cut sequin edges scratch, and wear a soft camisole underneath.
22. Little Black Demon Dress Costume
This is the costume for the afternoon you realize the party is tonight. A little black dress you already like wearing, red tights, black ankle boots and a red belt make the base, and a horn headband with a clip-on tail does the rest. Five minutes of makeup is enough: red liner, mascara and berry lipstick. Add a red capelet and a heart-shaped bag if they're in the closet. If the weather turns, swap in thicker tights and a coat; the costume still reads.
23. Red Sweater Demon Dress Costume
A red sweater dress is the demon you can actually trick-or-treat in. A relaxed knee-length knit, opaque black tights and flat combat boots or cushioned sneakers mean you can walk for hours. Keep the horns small and the tail in light fabric so neither fights with a coat collar or a car seat belt. A messy bun, black liner and red lipstick are plenty. Fingerless gloves, a crossbody bag and a short hooded cape handle the cold, and washable face products save the sweater's neckline. Fasten the tail securely before you head out, since it's the first thing to fall off on a long walk.
24. Red Plaid Demon Dress Costume
Plaid makes the demon preppy, and it's the one I'd suggest for a school party or an office where costumes are welcome but the dress code still applies. A plaid pinafore over a fitted black turtleneck covers everything, with opaque tights and chunky loafers. Small red horns, a removable black tail and a cropped black cape come off in seconds if a meeting gets serious. Clean winged liner and a dark red lip stain last through a full day better than gloss. A black satchel replaces a prop, and black nail polish is optional.
25. Plus Size Wrap Demon Dress Costume
A wrap dress is my first pick for a plus-size demon, because you set the waist yourself and can ease it after dinner. Red velvet or black jersey with sleeves and a length you like, opaque tights and supportive boots make the base. Medium horns suit the proportion better than tiny ones, which can look lost. Clip the tail to a belt instead of the dress fabric so its weight doesn't pull the wrap open. Smoky plum eyes, a satin lip, statement earrings and a flowing cape bring the drama, and a hidden snap at the wrap's crossover keeps it closed all night.
26. Maternity Demon Maxi Dress Costume
For a pregnant demon, an empire-waist knit maxi leaves room through the bump and hips and still looks like a gown. Supportive flat boots matter more than anything else here, plus maternity tights if it's cold. I avoid adhesive accessories, since skin can be more sensitive in pregnancy, so a light horn headband and a soft tail tied to a separate ribbon belt are kinder choices. Gentle bronze shadow, defined lashes and a moisturizing berry lip keep the face comfortable. A capelet that ends above the knee won't tangle, and a small crossbody bag keeps water close.
27. Modest Long Sleeve Demon Dress Costume
Coverage takes nothing away from a demon. A high-neck, long-sleeved maxi with a gently defined waist, opaque tights and flat knee-high boots covers you completely. If you wear a head wrap or under-scarf, set the horns on a separate thin band over it and pin through the band rather than the scarf fabric, so the horns don't slide back. Plum shadow, fine black liner, berry lipstick and a few gems at the temples carry the fantasy. A long cape should end several inches above the floor so it doesn't catch on steps, and decorative cuffs with a small structured bag round it out.
28. Demon Mini Dress With Tights Costume
A mini works for a public party when the layers under it are thought through. Pick a long-sleeved red or black mini with opaque tights or patterned leggings, then flat knee-high boots for walking. Sit, bend and reach in it in front of a mirror at home; that test tells you more than any fitting room. Curved horns, a detachable tail and a short shoulder cape make it read as demon. Smoky black and red shadow, clean liner and a muted red lip finish the face, and a wide belt plus a compact crossbody bag keep your hands free.
29. One Shoulder Demon Dress Costume
An asymmetric neckline gives the demon a modern line, and I like to echo that angle in the horns by tilting the headband slightly toward the bare shoulder. A one-shoulder midi in a stretch fabric, opaque tights and coordinating ankle boots make the base, with a single shoulder cape on the covered side for balance. Sweep the hair into a side ponytail so the neckline stays on show. Fashion tape inside the edge and a convertible bra underneath keep everything where it belongs. Metallic shadow, sharp liner, berry lips, one statement cuff and a small clutch are all it needs.
30. DIY Tulle Demon Dress Costume
This is the one I'd sew on a weeknight. Cut tulle into long strips and loop each one around a piece of elastic sized to your waist with a lark's head knot; mixing red, burgundy, orange and black reads as flame. Trim the overskirt to knee length while you're wearing it, because tulle settles longer than it looks on the table. Wear it over a plain red or black dress with opaque tights and boots. Craft-foam horns on a ribbon-wrapped headband and a soft felt tail keep everything light, and use face-safe glitter only, never craft glitter near the eyes. Before you go out, run a finger over every glue seam and wire end, since a sharp point snags tulle instantly.
Red Makeup Without a Red Collar
Nearly every dress above pairs with red, plum or black around the eyes, and those deep pigments are exactly the ones that stain fabric and irritate skin. Not every bright red product is meant for the eye area, so read the label and patch-test anything new on the inside of your wrist the day before. Then it's a matter of keeping the color on your face and off the dress.
- Set cream products with translucent powder pressed in with a puff, not swept, and let it sit for a few minutes before you dust off the excess.
- If the dress zips up the back, do the makeup first and step into it. If it goes over your head, drape a thin scarf over your face while you dress.
- Keep the strongest red near the eyes and away from the jawline, where collars, capes and fur trims rub all night.
- Remove it with an oil or cleansing balm first and a regular face wash second. Scrubbing deep red with plain water just spreads it around the eyes.
Face gems stuck on with lash glue lift off easily once you press a little oil around the edges. Never peel them off dry, especially near the eyes, because the skin there is thin and marks easily.
The Dress Decides Everything Else
Every look here comes down to the same few decisions: a dress you can move in, horns that stay put, and a face that matches the dress color. Red velvet and black lace are the safe classics, while ice blue, moss green, pink and starry navy are the ones people will ask you about. A night or two before, walk around the house in the full costume, sit down in it, and go through a doorway if you have wings or a cape. Soft materials, secure fastenings and makeup made for skin will carry you through the evening, from the last-minute little black dress to the maternity maxi.
