DIY Rumi KPop Demon Hunters Costume for Kids (No Sew!)

I’ve been working on a KPop Demon Hunters-inspired costume for my daughter. I originally thought I’d just buy the Halloween costume for her, but then most of them were over $100! I really don’t like spending more than $30 on a Halloween costume, especially if it has multiple parts that can get lost easily. Everything I got for this Rumi costume is available on Amazon. The whole thing took me a couple of hours to put together. (Mostly because I decided to sew the strips of sequins on which you definitely do not need to do).

Most of this is no-sew because I used adhesive fabric tape – I LOVE that stuff. Read on for exactly what I used and how!

Here’s what I used for our DIY KPop Demon Hunters costume:

The base is a white long sleeve athletic top and white shorts. I bought a black sequin jacket, cut it to be a cropped length, and then used adhesive fabric tape to add the black sequin fabric (that I had cut off of the jacket) to the shorts on either side. I added a gold North Star charm to the zipper of the top, and used fabric tape again to add gold sequins around the neck of the top. I used this chain belt to add chain around the arms of the jacket. (I also disconnected the little charms that are on the belt and used one of those for the middle of the black X across the jacket. This I did have to sew on to get it to stay put.) For the black X – I put it on the jacket instead of the white top, and I used velcro dots to keep it in place.

We are adding the gold chain belt and for her hair, the purple hair braid, and then using purple hair wax.

You can see in the below where I didn’t have the sequins on yet- or the little medallion in the middle of the black X. And also where I draped the chains. You could actually just buy a roll of chain but I bought premade chain belts and just tacked them with a few stitches so they’d stay in place!
