Rei Ami didn't think too far outside the golden box when coming up with her Halloween costume this year.
The singer behind the musical voice of KPop Demon Hunters' Zoey dressed up as the animated character for Heidi Klum's 24th Annual Halloween Party, slaying the first look her character wears in the film—patchwork parachute pants while jumping out of a plan, naturally—with down-to-the-last-detail styling.
How it's done, indeed.
"Oh my god, it's everywhere, I can't get a break from it," Rei told E! News on the red carpet outside New York's Hard Rock Hotel Oct. 31, referring to the ubiquity of KPop Demon Hunter-inspired costumes this year. "And I'm not complaining, please!"
The 30-year-old showed off the intricate embroidery, noting the symbolic sea turtle and a hibiscus, which is the national flower of South Korea. And to complement Zoey's shin-kal (aka her magical throwing knives), Rei also sported a fierce manicure.
All told, she shared, it only took her "like three hours" to get ready, assuring E!, "It wasn't bad."
But admittedly, Rei added, "I really put my tailor through it. I sent my measurements in like a week ago. He has not slept."
So, a heartfelt apology to Rei's tailor.
But the effort was worth it, and it came together "in the span of 36 hours. I literally walked in earlier today for my fitting."
Meanwhile, Rei still hasn't been able to really able to wrap her mind around the mega-success of KPop Demon Hunters, as who could have expected just how much the Netflix film would own the summer?
Now it's fall and "I can't and I still haven't," she marveled. "This is a cultural phenomenon."
"I'm so honored and in awe," she gushed, "and just truly humbled by the power of music and good art and how it can really, truly—it sounds so cliché—change the world. That's exactly what this film and this soundtrack did, and it brought so much hope and light into such a dim, grim world, and I feel really privileged to be a part of it."
With no less than one-third of the weight of the world resting on Zoey's shoulders, Rei is planning on "world domination" for herself in 2026.
Though asked if she could share details about whether a sequel to Netflix's most popular movie of all time is, in fact, in the works, Rei told E!, "I'm waiting for the call, just like you! You're gonna find out when I do, so we'll chat then."
