If you’ve watched Netflix’s KPop Demon Hunters even once, you already know why it’s dominating this year’s costume searches. Rumi, Mira and Zoey — the demon-slaying girl group HUNTR/X — have crossed over from screen to spooky season: Spirit Halloween released officially licensed HUNTR/X costumes, and it’s been named a breakout costume trend for 2026.
Here’s the catch: the licensed costumes sell out fast, and adult sizes land online later in October. The good news? All three signature looks — from the opening “How It’s Done” number — are easy to build from a thrift store, a wig, and a few craft supplies. This guide breaks down each costume piece by piece, with realistic costs and where to actually find each item.
Which look should you go for?
The trio wears several outfits across the film, but for Halloween go with the most instantly recognizable one: the “How It’s Done” performance looks. They’re bold, color-coded (yellow Rumi, pink Mira, teal-and-blue Zoey), and read clearly even in a dark party room.
Rumi Halloween Costume DIY
Rumi is the purple-braided leader of HUNTR/X, and her yellow-jacket look is arguably the KPop Demon Hunters Halloween costume — it’s the one most licensed costumes and merch are based on.
What you need
- Cropped yellow jacket. Rumi wears a bright yellow cropped moto-style jacket with a spiked shoulder pad on her left shoulder. Best bet: a yellow or mustard cropped jacket from a thrift store or Amazon (roughly $15–$30). Fake the spikes with small metal studs or cones from a craft store glued onto one shoulder.
- White mock-neck crop top. A plain white ribbed crop top with a higher neckline. You probably own something close; a basic one runs about $8–$15 new.
- High-waisted black shorts. Denim or faux-leather — thrift for under $10.
- Layered necklaces. A couple of thin chains; costume jewelry sets at discount stores run $5–$10.
- Platform or lace-up boots. Use your own chunky boots; thrift stores usually have something workable for $10–$20.
- Rumi’s weapon (optional prop): her sword, the singeom. A foam or cardboard sword painted silver with a gold handle reads perfectly from a distance. Handmade prop versions run about $15–$30 from craft sellers if you’d rather buy than build.
Rough total: $30–$75, depending on how much is already in your closet. For comparison, Spirit Halloween’s licensed adult Rumi costume runs about $70, with the purple braid wig sold separately for about $30.
Hair and makeup
The purple braid is Rumi. Options from cheapest to easiest:
- Braid your own hair with purple clip-in extensions or a purple braided hairpiece ($10–$20).
- Buy a long purple wig ($15–$30 on Amazon or Etsy) and braid it yourself — braiding a wig before you put it on is much easier.
- Temporary route: a long ponytail or braid with purple hair-color spray ($8–$12). It washes out — ideal for one night.
Makeup: full K-pop idol stage glam — sharp winged eyeliner, straight brows, flushed berry blush, glossy lip. Optional touch: Rumi’s skin carries demon-mark patterns in the film, so a few curved purple eyeliner swirls on your forearms gives fans something to spot up close.
Mira Halloween Costume DIY
Mira is the group’s lead dancer — tall, sarcastic, styled in black and yellow with hot-pink hair. Her “How It’s Done” outfit is a streetwear stage look that translates well to a DIY build.
What you need
- Black short-sleeve crop top with graphic. Mira’s tee has a blue wave print with “WON’T MISS” in hot pink. DIY: a plain black crop top ($8–$15) plus pink and blue fabric markers (about $5 a pack). It’s a two-minute craft and it makes the costume unmistakable.
- Yellow denim miniskirt. A saffron or mustard-yellow denim skirt, high-waisted. Thrift for under $10; new ones run roughly $15–$25.
- White chain belt. A long thin chain necklace from a discount jewelry section ($3–$8) wrapped twice around the waist works perfectly.
- Crimson norigae charm (optional). The traditional Korean ornament at her hip can be faked with a red tassel keychain from a craft store.
- Black choker. A plain black ribbon or velvet choker ($3–$5); add a small charm for the screen-accurate detail.
- Black fingerless gloves. About $5–$10 anywhere; cut the fingers off cheap black gloves if you can’t find fingerless ones.
- Thigh-high boots (or the illusion of them). Fake it: black thigh-high socks or stockings ($8–$12) over your own black boots. From more than a few feet away, nobody can tell the difference.
- Mira’s weapon (optional prop): her woldo, a long glaive. A broomstick handle spray-painted black with a cardboard blade is the classic DIY.
Rough total: $35–$80, with the socks-instead-of-boots trick being the biggest money saver.
Hair and makeup
Mira’s signature is her hot-pink hair in two twintails. A long hot-pink wig ($15–$30) split into two high pigtails is the simplest path — look for a “twintail” or “twin ponytail” wig to skip the styling. If you’d rather use your own hair, pink hair-color spray over two ponytails works, though it won’t have the same drama.
Makeup: Mira’s look is cooler and edgier — smoky liner, a nude or mauve lip, minimal blush. Small triangle dangle earrings finish the face.
Zoey Halloween Costume DIY
Zoey is HUNTR/X’s youngest member and main rapper — teal, black, yellow and blue, with her hair in black double buns.
What you need
- Teal halter-neck crop top. A plain teal or turquoise halter crop top ($10–$18). Any bright teal athletic-style crop top from a discount store gets you 90% of the way there.
- Graphic parachute pants. Zoey wears loose black, yellow and dark-blue patterned cargo pants with teal straps. The budget version: black cargo joggers ($15–$30) with a few swipes of yellow and blue fabric paint on the legs.
- Chunky sneakers. Black sneakers with yellow laces, or just swap the laces on sneakers you own (a few dollars).
- Gold bracelet and bangle. One or two chunky gold-tone bracelets ($5–$10).
- Black arm pouch. A small black wrist wallet or phone armband ($5–$10) stands in for the pouch on her arm.
- Gold norigae pendant (optional). A small gold tassel charm clipped to a belt loop.
- Zoey’s weapons (optional props): her twin shin-kal blades. Foam dagger props are the safest party option; kid-safe handmade versions run roughly $10–$25.
Rough total: $40–$85, with the pants being the piece that takes the most creativity.
Hair and makeup
Zoey’s black double buns with blunt bangs are her most recognizable feature. Three ways to get there:
- Space buns with your own hair plus black hair-color spray — free if your hair is already dark, about $8 for the spray if it isn’t.
- A black bob wig with bangs ($12–$20) split into two buns, or a pre-styled double-bun wig.
- Braided space buns: two Dutch braids wrapped into buns — the closest to the film, and it holds all night with bobby pins.
Makeup: youthful and bright — glossy lips, rosy cheeks, playful liner. Zoey’s the youngest of the three, so keep it fresh rather than dramatic.
Doing all three as a group costume
This is a top-tier trio costume — arguably the easiest recognizable three-person group of 2026. A few tips:
- Color-code clearly. The whole trick is that each character owns one hero color: yellow for Rumi, hot pink for Mira, teal/blue for Zoey. If those three colors are loud and visible, the group reads instantly.
- Match the wig quality. Buy all three wigs from the same place so they look consistent — mismatched wig quality is what makes group costumes look uneven.
- Add the weapons. Foam or cardboard versions of Rumi’s sword, Mira’s glaive and Zoey’s twin blades take the trio from “K-pop fans” to “demon hunters” in photos. Keep them party-safe and check the venue’s prop policy.
- Don’t forget Derpy. The little blue tiger sidekick makes a perfect fourth — a blue hoodie with ears and painted whiskers.
Buying the licensed costumes vs. DIY
If crafting isn’t your thing, the officially licensed Spirit Halloween costumes are the shortcut: Rumi’s set (yellow jacket, tank, shorts and boot covers) runs about $70 for adults, with her purple braid wig sold separately for about $30. Mira and Zoey sets are in the same ballpark. Kids’ sizes hit stores in early October, with adult sizes landing online later in the month — but several sizes sold out online last year, so check stock early rather than waiting until the last week of October.
The honest math: DIY runs roughly $30–$85 per costume versus about $100+ for the licensed set plus wig. DIY also lets you wear real boots and keep pieces you’ll actually use again. The licensed route wins on zero-effort accuracy.
Frequently asked questions
Who are Rumi, Mira and Zoey?
They’re the three members of HUNTR/X, the fictional K-pop girl group at the center of Netflix’s animated film KPop Demon Hunters (2025). By day they’re chart-topping idols; by night they secretly hunt demons.
What is Rumi’s most recognizable Halloween costume?
Her “How It’s Done” opening-number look: a bright yellow cropped jacket with a spiked shoulder pad, white crop top, black shorts and the long purple braid. It’s the version every licensed costume is based on.
How much does a DIY KPop Demon Hunters Halloween costume cost?
Expect roughly $30–$85 per costume depending on what you already own. The biggest variables are the wig ($12–$30) and whether you need boots or can use your own. Licensed Spirit Halloween sets run about $70 plus $30 for the wig.
Where can I buy a KPop Demon Hunters costume?
Spirit Halloween carries the officially licensed Rumi, Mira and Zoey costumes in kids’ and adult sizes, and licensed sets also appear on Amazon. Etsy sellers offer handmade and unlicensed versions — check delivery dates, since many ship internationally, so order early.
How do I do Rumi’s purple braid without a wig?
Braid your own hair and weave in purple clip-in extensions or a braided hairpiece (about $10–$20). For a one-night option, a long ponytail or braid with purple temporary hair-color spray washes out completely.
Can this work as a couples or family costume?
Absolutely — it’s one of the most flexible group costumes of 2026. Two people can do any pair (Rumi + Zoey is a popular combo), and a fourth can join as Derpy the tiger or a Saja Boys member in pastel idol styling.
