If your kid watched KPop Demon Hunters once, they watched it forty times. It is the costume request of the year for girls six to fourteen, and a surprising number of adults are going as HUNTR/X too.
The problem is not finding a costume. It is finding one that arrives on time and looks like the film. Here is how I would shop it.
Who to go as
- Rumi. Purple hair in a long braid, the leader. Most requested, sells out first.
- Mira. Tall, red-haired, the cool one. Good when a friend already took Rumi.
- Zoey. The youngest, looser outfit, the most comfortable to wear all night.
- Saja Boys (Jinu). The rival boy band. The way in for brothers, dads and boyfriends.
Kids costumes
1Rumi costume (girls)
$CostumeKidsThe purple stage outfit is the most recognised of the three. Most kids sets include top, shorts or skirt and leg pieces.
Check before buying: Whether the braid wig is included. Half the listings sell it separately.
2Mira costume (girls)
$CostumeKidsThe tall, red-haired one. Good pick when a friend already called Rumi.
Check before buying: Fabric on the jacket. Cheap sets use thin satin that wrinkles in the bag.
3Zoey costume (girls)
$CostumeKidsEasiest of the trio to wear all evening: looser cut, sneakers work.
Check before buying: Size chart in cm, not age. Asian sizing runs one size small.
Adult costumes
Adult cosplay sets are closer to the film than kids sets, but many ship from overseas. Read the delivery date, not the “usually ships” line.
4Rumi costume (women)
$$CostumeWomenAdult cosplay sets are cut closer to the film than the kids versions.
Check before buying: Shipping date. Many adult sets ship from overseas and take two weeks.
5Jinu / Saja Boys costume
$$CostumeMenKidsGives boys and dads a way into a HUNTR/X group without wearing the trio outfits.
Check before buying: Whether the hat is included. It is the part people recognise.
The pieces that make it
The wig matters more than the outfit. A purple top with the wrong hair reads as “pop star”. A purple braid reads as Rumi from across the room.
6Rumi long purple braid wig
$WigKidsWomenThe braid does more work than the outfit. Without it, Rumi reads as “purple pop star”.
Check before buying: Heat-resistant fibre if you want to restyle it, and an adjustable cap.
7Demon hunter sword prop
$PropKidsAdultsPhotos look finished with a prop in hand.
Check before buying: Foam or plastic only. Some school and venue rules ban hard props.

Shopping tips
- Order now. Kids sizes are the first to go out of stock.
- Size up one on cosplay sets. Check the chart in cm.
- Check if the wig is included. Most listings: no.
- Make it a trio. Three friends in matching outfits is the photo everyone wants.
Sold out in your kid’s size? A yarn braid and a sparkly top get you most of the way: more in homemade costumes.
