How to Create a Last-Minute KPop Demon Hunters Halloween Costume

"The Rumi look is actually simpler than we're thinking," insisted Crownholm. "So you need some shorts, black shorts, denim shorts. Again, you can still run to the craft store and get your electrical tape. I have on fishnet tights with a little bit of rhinestone just to give it a little bit of shine." 

She also added silver and pink electrical tape onto her existing black boots and then, with the jacket, "Have fun decorating with whatever it is that you can find."

And if she's sharing nothing but the truth now, you can even do a blend.

"It's not going to be the exact look," she acknowledged, "but it's going to be your kids' perfect look for Halloween."

The one must for any wannabe Rumi is her signature purple braid. 

"For those of you that are thinking, maybe the Rumi braid looks more difficult than it is, there is no braiding involved," she explained. "It's actually tiny rubber bands that you're going to fold behind itself so a lot easier than you think. You can add in some gold ribbon or trinkets to give it that extra little golden shine, but then you're just going to pin it into your own hair. And that's it." 

And if you truly want to be shinin' like you're born to be, you can add a Derpy-themed candy container. 

Starting with a $2 plastic pumpkin pail, "I did blue metallic paint, and then I had fun with some paint pens," said Crownholm. "And then I added rhinestones, just because I wanted to have a lot of fun, and I added whiskers with those light up toys that you get, a little bit of clay, a little bit of felt on the ears." 

Bottom line, she added, "Go have fun finding materials, source what you have at home, and then just create." 

Locked and loaded, you were born for this. There ain't no point in avoiding it. But if you're looking for more inspiration, check out the killer costumes stars have served up so far this spooky season.
