The cartoon adventure film KPop Demon Hunters, which Netflix quietly released this past summer, has become the year’s largest cultural hit. Sony, with minimal faith, licensed the movie to the streamer during development, similar to other Netflix exclusives not based on existing IP, it launched with little promotion. Quality prevailed: KPDH became Netflix’s biggest movie ever and is expected to dominate the Academy Awards in animated feature and best song categories. But first, it’s targeting complete October 31 takeover.

Costume Mania Sweeps Through Neighborhoods

Drawing from the myriad costumes sported by musical acts Huntrix and the Saja Boys throughout the film, the trend seemed predictable. But it wasn’t until joining a Netflix theatrical singalong with audiences young and old sang along to “Golden” flawlessly did it hit me: Absolutely, it’s happening. KPDH personas are set to invade local neighborhoods on trick-or-treat night.

Costume Market Running at Full Tilt

A quick look on Etsy reveals the KPDH costume economy operating at peak capacity. Inexpensive Baby Saja wigs are selling rapidly via sites such as AliExpress. Everything you’d imagine is available, including cozy versions of Derpy the blue demon tiger. But Netflix itself deserves credit: While the company may not have predicted the KPDH mania pre-launch, the streamer’s official store is packed with premium outfits and collectibles, along with one product so outrageous it demands attention.

Goodness

Retailing for under $40, available in extra-small to double-extra-large, the KPop Demon Hunters “Abby Saja Abs” T-shirt showcases a disturbingly accurate depiction of the demon boy band member’s eight-pack. If you wear this on Halloween, expect bystanders’ eyes to pop.

Delivery & Deadlines Concerns

The big question among KPDH enthusiasts is if those wanting outfits have enough time to gather components. Netflix’s store guarantees delivery in 5–8 business days, with expedited shipping cutting it to 3–5 days. That’s ample time—for now. With international tariffs and shipping delays making AliExpress or Temu orders unpredictable, Netflix might be the most dependable option unless an Etsy seller guarantees delivery within 27 days.

Homemade Options and Final Thoughts

Still, seasoned cosplayers insist: There’s time to craft it yourself! TikTok and Reels creators are producing how-to guides at a rapid pace. Frankly, the Abby Saja abs look could be the KPop Demon Hunter version of a cringey vintage T-shirt—extremely awkward rather than hilariously funny. We’ll have to wait and see. As a lower-risk alternative, opt for a DIY Rumi hairpiece.
