A KPop Demon Hunters costume comes down to two things: a bright stage outfit and the right hair, then a few props to finish it. Huntr/x members Rumi, Mira and Zoey work as a trio, while the Saja Boys make a strong group look in coordinated black. Get the pieces below and you are sorted for Halloween or a themed party.

How to get the look: start with the stage outfit and the wig, which do most of the work, then add makeup and a prop for stage photos.
Rumi
Rumi leads the group, so her look is the one most people reach for. The signature purple hair sets the whole costume in one move, so start there, then build a bold stage outfit in purple and blue tones with strong graphic eye makeup.
Rumi purple wig and plait
The piece people recognise first. Pre-stretched purple braiding hair gives you Rumi's signature plait without styling your own hair.
Mira and Zoey
Mira leans cooler and sharper, Zoey brighter and more playful, so split the palette between you if you are going as a group. A coordinated stage outfit ties all three Huntr/x members together, and a long coloured ponytail keeps the hair reading on theme without an identical costume.
Idol stage group outfit
The heart of the costume in one buy. A stage performer uniform that suits any of the three Huntr/x members, so a group can coordinate without matching exactly.
Purple braided ponytail
A long pre-stretched ponytail in purple for a second Huntr/x member, so two of you can share the colour theme.
The Saja Boys
The rival boy band works best as a group in coordinated dark outfits: black tailoring, leather and silver detailing, with neat styled hair. One bold accent across the group keeps them reading as a unit.
Saja Boys black costume set
A Jinu-style set that does the Saja Boys look in one go: black outfit with hat, chains and jewellery, so you are not hunting down each piece.
Finishing touches
The hair and makeup carry these costumes more than anything, so budget a few minutes with eyeliner or face paint. A prop helps for stage photos and ties the look back to the demon hunting side of the show.
Purple hunter daggers
The small details sell it. A set of purple plastic daggers gives you a safe prop for photos and matches Rumi's colours.

Frequently asked questions
What do you need for a KPop Demon Hunters costume?
Two core pieces do most of the work: a bright stage outfit and the right wig. For Rumi that means purple hair and a purple and blue outfit; for the Saja Boys it means a coordinated black outfit. Add bold eye makeup and a prop to finish it.
Who are the Huntr/x members?
Huntr/x is the girl group at the centre of the show: Rumi, who leads, plus Mira and Zoey. As a trio you can coordinate stage outfits and split the colour palette so no two costumes are identical.
How do you dress as the Saja Boys?
Go as a group in matching black: dark tailoring, leather and silver detailing, with neat styled hair and one shared accent colour. A ready-made black costume set with hat and chains is the quickest way to kit out the band.
What hair do you need for Rumi?
Rumi's signature is long purple hair, usually braided. A pre-stretched purple wig or plait gives you the look without dyeing or styling your own hair, and it is the piece people recognise first.
Can you do KPop Demon Hunters as a group or couple?
Yes. The show is built for it: three Huntr/x members and the Saja Boys mean a group can split the characters, and a couple can pair one Huntr/x look with one Saja Boys look.
