Channel Rumi, Jinu and more with these ‘KPop Demon Hunters’ Halloween costume ideas

With KPop Demon Hunters-inspired outfits emerging as the top choice for Halloween costumes this year, here’s our guide to recreating some quirky looks from the film. From Jinu’s eerie yet effortlessly chic hanbok ensemble to Rumi’s dazzling “Golden” look, these Halloween costume ideas will help you channel your favourite KPop Demon Hunters characters in style.

The Netflix animated movie premiered on 20 June 2025 and quickly became a global sensation, amassing over 100 million views in less than two months. Alongside its engaging storyline and hit soundtrack, the characters and their iconic costumes also garnered widespread acclaim.

Speaking to NBC News, Boston-based fashion blogger Jean Wang shared her excitement about her 7-year-old daughter, Nori, wanting to dress up as Rumi from KPop Demon Hunters. For Wang, Nori’s choice of costume carries deep significance. “It’s definitely refreshing and exciting to see the ‘it’ costume of the year, for people of all backgrounds, being a female Asian character,” she said.

Dress up as your favourite KPop Demon Hunters characters with these Halloween costume ideas

Jinu’s “Your Idol” hanbok look

First off, grab a purple marker and draw those eerie patterns across your skin. Next, put on claw-like nail extensions, add fangs, and wear golden contact lenses to achieve that otherworldly look. Half the work is done.

For the outfit, go for a black hanbok. The full set includes a long jeonbok vest, a jeogori top, baji trousers, a sejodae sash tied around the waist, and hye shoes. Don’t forget the traditional Korean hat, the gat. You can accessorise further with gold earrings or hoops, or keep it simple for a more authentic vibe.

Want to skip the hat? Add some purple highlights and tousle your hair a little to channel Cha Eun-woo’s pre-military charm. If you look slightly stressed, that’s perfect — Jinu always did, thanks to his little Lord Gwi-ma problem.

Style note: To complete this Halloween costume, master Jinu’s steps from the “Your Idol” choreography in KPop Demon Hunters.

Rumi’s “Golden” outfit

To nail Rumi’s “Golden” outfit, start with a white high-neck crop top featuring gold trim around the collar. Pair it with white shorts — these can be DIY-ed with black laces or enhanced with gold waist chains for added flair. Then, layer on a black cropped jacket adorned with gold chains and embellishments.

Elevate the look with a pair of white knee-high or ankle boots featuring black criss-cross laces. Don’t forget Rumi’s signature long purple braid. It’s the finishing touch that completes the outfit.

Style note: To complement this Halloween costume inspired by KPop Demon Hunters, try Douyin-style makeup, a popular Chinese technique that typically uses shimmery eyeshadow, pigmented pink blush, and blurred lips. Alternatively, opt for gold eyeshadow, generous blush, highlighter, and tiny rhinestones near the eyes to achieve a radiant, ethereal look.

HUNTR/X’s battle outfits

No one does demon-fighting glam like HUNTR/X. Remember their “Kill Saja” nail art?

To recreate this sleek look, go for a black faux-leather jumpsuit or a leggings-and-crop-top combo. Slip into chunky platform boots and slick your hair back or braid it tightly with neon streaks woven through.

Lastly, grab a cosplay sword and wrap it in LED string lights or get glow sticks to mimic their signature blue energy blades.

The Derpy look

With cerulean fur, black-and-white stripes, and rosette patterns, Jinu’s supernatural pet is both adorable and delightfully unhinged. This Halloween, you have two fun ways to bring him to life.

For a full Derpy transformation, start with a fuzzy blue hoodie or faux fur jacket, then add black tiger stripes using fabric paint or tape. Use bright face paint to recreate the yellow-and-pink eyes, and don’t forget the fangs.

If you prefer a subtler look, pair a sleek black outfit with blue striped gloves, fuzzy cat ears, or even a plush Derpy tail. Lastly, carry a Derpy plushy. You can purchase it at the official Netflix shop for KPop Demon Hunters merch.

The ancient hunters look

For this KPop Demon Hunters Halloween costume, think long, layered robes. You can either go for a hanbok-inspired robe or a flowy kimono-style dress secured with a belt at the waist.

Add metallic trims or embroidered, colourful edges if you want extra flair. Style your hair in a regal updo or half braid, and accessorise with ornate jewellery, decorative hairpins, and beaded ornaments. Carry a cosplay bow, staff, or buchae (Korean hand fan) to complete the look.
