KPop Demon Hunters Costumes: DIY Rumi, Mira, and Zoey Looks

If you spent any part of 2025 with KPop Demon Hunters stuck in your head, you already know why this is the costume everyone wants this year. Netflix’s animated musical about Huntrix, the K-pop trio secretly fighting demons, became the platform’s most-watched title of all time, and when Google released its Halloween search data, Rumi landed as the number one most-searched costume in the country, with Zoey and Mira right behind her.

The good news is you do not need a licensed costume to pull this off. Official Netflix x Spirit Halloween sets sold out fast last year, but every piece of a Rumi, Mira, or Zoey look can be built from your closet, a thrift trip, and a little light sewing. This guide breaks down each character’s real look, gives you a numbered build plan, and points you to the sewing basics you need along the way. For the full process from start to finish, see our guide on how to make a costume, and browse our Halloween costume ideas hub for more inspiration.

Who You’re Dressing As (Quick Character Key)

Fans notice hair color and weapon mismatches fast, so get the details straight before you pull anything off the hanger.

• Rumi: Long, deep-purple hair in a single braid. Palette is purple, black, and magenta. Weapon is the Saingeom, a conjured magical sword.
• Mira: Long, straight, thigh-length hot-pink hair with pigtail sections. Palette is pink, yellow, and black. Weapon is a curved glaive based on the traditional Korean woldo.
• Zoey: Black hair (it can read dark blue in certain light) styled in twin braided space buns. Palette is blue, teal, and yellow. Weapon is a set of six Spirit Blade throwing knives, based on the shin-kal used by Korean shamans.
• Saja Boys: The rival demon boy band, led by Jinu. Dark, monochrome hanbok-inspired outfits, mostly black, worn with the gat, a wide-brimmed Korean hat. No weapon, since they’re a vocal and dance group.
• Derpy and Sussie: The trio’s supernatural companions, a blue-furred tiger and a six-eyed magpie inspired by Korean folk art. A fun optional add for a group costume, not a core look you need to nail.

The Rumi Costume

Rumi’s whole identity is that deep purple braid and the patched-up jacket she wears in battle. Her demon-hunter markings, thin jagged lines that appear along her face and neck under stress, are the detail people notice first.

The verified look: a structured jacket loaded with colorful patches and embellishments, a sleeveless crop top with a chest-crossing ribbon detail, coordinating shorts, a magenta felt belt, and combat boots, all built around that single long purple braid.

1. Base layer: Start with a black or dark sleeveless crop top (thrift one or cut down an old tank) and black shorts or a skort.
2. Jacket: Thrift a cropped bomber, varsity, or track jacket in black or purple. Add colorful patches, iron-on appliques, safety pins, and fabric-paint accents to mimic the embellished look. Just a needle and thread or fabric glue for the patches, nothing advanced.
3. Belt: Tie or safety-pin a magenta or fuchsia sash at the waist as a stand-in for the felt belt.
4. Hair: Go with a long purple wig braided into one thick braid, or clip purple extensions or hair chalk into your own hair and braid it yourself. A little purple hairspray on the ends sells the ombre look.
5. Weapon: Cut a sword shape from foam board or cardboard, paint it silver and purple, and tape a strand of LED string lights along the blade for a glow effect. Skip metal or hard plastic, especially for kids.
6. Makeup: Purple eyeshadow, winged eyeliner, and a few thin jagged lines in purple face paint along the cheekbone or neck complete the demon-mark effect.

The Mira Costume

Mira reads instantly by her hair alone. That long, straight, thigh-length hot-pink color with two smaller pigtail sections is unmistakable.

The verified look: a graphic T-shirt with a painted magenta, light-blue, purple, and white design, a yellow skirt with wide felt panels, and pink-accented boot covers over dark boots, topped off with gold bangles and a deep smoky eye.

1. Top: Take a plain graphic tee and add fabric paint or an iron-on transfer in a magenta and purple splatter pattern. Tuck it or knot it at the waist.
2. Bottom: Thrift a yellow pleated or A-line skirt, or customize a plain yellow skirt by gluing or sewing felt strips to the hem for that wide felt-panel texture.
3. Boots: Wrap dark boots with pink fabric or felt “boot covers,” gluing or pinning them around the ankle for the two-tone effect.
4. Hair: A long, straight hot-pink wig gets you there fastest. If you’re using your own hair, temporary pink spray plus two small clipped-in pigtail sections mimics her signature part.
5. Weapon: Build a curved glaive from a foam pool noodle or cardboard on a dowel, painted gold or silver. Keep it lightweight and blunt-tipped.
6. Makeup: A deep plum smoky eye with strong drawn brows finishes the face. Stack a few cheap gold bracelets on one wrist for the bangle detail.

The Zoey Costume

Zoey has the most streetwear-leaning look of the trio, and the easiest hair to DIY. Twin braided space buns with a little fringe read as “Zoey” from across a room.

The verified look: a strappy blue top, colorful printed pants with teal ribbon loops creating a suspended detail at the waist, a yellow felt tassel pinned at the hip, and a matching armband, with black hair in twin space buns and light shimmer eyeshadow in teal, blue, and yellow.

1. Top: Wear a strappy blue crop top or camisole, thrifted or layered from two tanks for a strappy effect.
2. Bottom: Reach for colorful printed pants or leggings, joggers or cargo pants with a bold print work well. Loop a teal ribbon from a front belt loop to a back loop to recreate her signature suspended detail.
3. Accent: Hot glue yarn or felt strips to a hair clip or safety pin to make a quick no-sew hip tassel in yellow.
4. Hair: Twin space buns with micro-bangs are the simplest DIY look of the whole group. This works with your own hair, a wig, or clip-in bangs paired with bun donuts.
5. Weapon: Make a set of foam or cardboard “throwing knives” with felt tassels attached, bundled in twos or threes, and worn in a fabric thigh pouch or belt holster. Never use real or hard-edged props for kids.
6. Makeup: Teal, blue, and yellow eyeshadow with a bit of shimmer and a glossy lip round out the most kid-friendly, low-fuss makeup option of the three.

Make It a Group Costume

Because Huntrix is a trio, this is one of the strongest friend-group or sibling costume ideas of the year. Each look uses a completely different color story, purple for Rumi, pink and yellow for Mira, blue and teal for Zoey, so three people never clash. Every build shares the same base formula: a thrifted top and bottom, a wig or hair trick, a foam prop weapon, and matching gold or silver accessories.

If your group has four people, add a Saja Boys member. Build a simple black hanbok-style robe (a dark bathrobe or kimono-style jacket works as a base) and top it with a gat, the wide-brimmed black hat that reads as “Saja Boys” even over a plain black outfit. A wide-brimmed black hat with the brim extended in cardstock, or a straw hat spray-painted black, gets you there.

For photos, commit to just one strong signature element per character rather than chasing every detail. Rumi’s braid, Mira’s pink hair, and Zoey’s buns get you recognized before anyone even looks at the outfit.

Sewing Shortcuts and No-Sew Hacks

Most of this trio is doable with zero garment construction. Thrifted base pieces, iron-on transfers, fabric paint, hot glue, and safety pins handle about 90 percent of the work. Light sewing helps most with hemming a thrifted skirt, tacking felt strips onto a skirt hem for Mira, taking in a bomber jacket for a closer fit on Rumi, and stitching tassels onto Zoey’s hip accent.

If you’d rather sew a piece from scratch, our guide to sewing tops and shirts covers crop tops and jacket customization, and our tutorial on how to sew a skirt walks you through a simple pleated, elastic-waist skirt if a thrifted yellow one is nowhere to be found.

For the no-sew route, keep these in your kit: iron-on adhesive appliques for jacket patches, fabric paint pens for graphic-tee designs, hot glue for felt trims and tassels, and double-sided fashion tape for a fast hem fix. Stage makeup carries a lot of the look too, a purple smoky eye, a plum eyeshadow, or a teal shimmer palette signals the character instantly, and a few small face gems along the cheekbone add sparkle with no painting skill required.

Props and Kid Safety

Keep every prop weapon soft: foam, cardboard, pool noodle, or lightweight plastic with no sharp points or edges. Many schools and trick-or-treat events restrict or ban rigid or metal-look prop weapons entirely, so check your school’s Halloween policy or your local trick-or-treat guidelines before sending a kid out with a sword or a set of throwing knives, even fake ones.

Skip battery-powered LED effects on props for very young kids since small parts and batteries are a choking risk, reflective tape gives you visibility without the hazard. Comfortable, broken-in sneakers or boots beat the exact combat-boot look for a night of walking, and any wig or hair chalk should be tested on skin ahead of time. Use real face paint for drawn-on markings, never craft or acrylic paint, especially on kids.

Frequently Asked Questions

What is the KPop Demon Hunters costume?

It refers to dressing as one of the three members of Huntrix, Rumi, Mira, or Zoey, from Netflix’s 2025 animated film KPop Demon Hunters, or as one of the rival Saja Boys. Each Huntrix member has a distinct hair color, outfit palette, and signature weapon, which makes them easy to tell apart and popular as both solo and group costumes.

How do I make a Rumi costume?

Combine a black crop top and shorts with a thrifted jacket, black or purple, decorated with patches and fabric paint, a magenta sash or ribbon belt, combat boots, and a long purple braided wig. Finish with a cardboard or foam sword painted purple and silver, plus purple-toned eye makeup with a few painted demon-mark lines.

What color is Rumi’s hair?

Rumi has long, deep purple hair styled in a single long braid. It’s her most recognizable feature and the fastest way to identify a Rumi costume at a glance.

Who are the Saja Boys?

The Saja Boys are the film’s rival K-pop boy band, secretly a group of demons led by Jinu, who wear dark hanbok-inspired stage outfits with the traditional wide-brimmed Korean gat hat as their most distinctive costume element.

Can I make these costumes without sewing?

Yes. Thrifted base pieces, iron-on patches and transfers, fabric paint, hot glue, and safety pins can recreate all three Huntrix looks with no garment construction required. Basic sewing only helps with details like hemming a skirt or attaching felt trim.

What are the Huntrix weapons?

Rumi wields the Saingeom, a magical sword. Mira wields a curved glaive based on the traditional Korean woldo. Zoey uses Spirit Blades, a set of six small throwing knives based on the shin-kal used by Korean shamans. For costumes, foam, cardboard, or soft pool-noodle versions are the safe DIY choice.
