Spooky season is finally upon us, which means you have a valid excuse to dress up as Rumi, Mira and Zoey — or, in my case, Derpy. The KPop Demon Hunters Halloween costume lineup is stacked, and last-minute shoppers still have a chance to grab theirs in time for Halloween, with most retailers offering shipping before Oct. 31.

There are plenty of ways to take the costumes even further, too, from Nerf swords and demon-slaying weapons to character-inspired wigs. The Saja Boys are also getting in on the action with ensembles for adults and kids, making a group costume almost too easy to pull together.

The little details are also what elevates the costumes. Rumi and Jinu’s demon markings can be recreated with glow-in-the-dark temporary tattoos, while a purple braided wig for your pet lets your cat or dog join the HUNTR/X crew.

Rumi’s “How It’s Done” outfit makes an obvious choice for anyone who wants to look like they walked straight out of KPop Demon Hunters. The costume includes several character-specific details, making it a fairly faithful option at this price point. The costume comes in sizes small through XL and includes the jacket, top, shorts, boot covers and detachable tassel. Kids’ options are also available, as well as Rumi’s iconic “Golden” outfit for ages 3 -12. Add her signature purple braid wig (sold separately for $22.99) and the transformation is complete.

Mira’s “How It’s Done” costume offers considerable value for its price, given the number of pieces and character-specific details included. Its inclusive sizing is also another point in its favor. The costume includes Mira’s yellow mini skirt, graphic tee and boot covers in adult sizes small through XL. Fans can also shop the kids’ options or Mira’s “Golden” outfit. The long, pink wig associated with the HUNTR/X member is not included in either costume, but can be purchased separately.

Zoey’s outfit is built around her rapper-meets-demon-hunter style, with a cropped halter top, parachute pants, an armband with a pouch and a detachable tassel. The adult version runs from small through XL, and kids’ designs mean several members of the family can replicate the look. For a more formal option, Zoey’s “Golden” costume lets kids ages 6 to 13 recreate her iconic stage presence.

Bring Rumi and Jinu’s demon scars to life with these shimmering temporary tattoos kids can design themselves. With over 70 designs, three foil cartridges and sparkly gems, the kit is a standout due to its roller application, and the tattoos last roughly 24 hours.

Fashion retailer Zara may not be known for its Halloween costumes, but even they couldn’t resist bringing KPop Demon Hunters to life with outfits for fans. This Netflix-approved three-piece “Golden” costume features a collarless jacket, polo shirt and Bermuda shorts.

The Saja Boys get their chance to steal the Halloween spotlight with this full-accessory costume. Available in sizes S-3XL, the adult version includes a long black robe with detailed accents, a wide-brim hat and jewelry, creating a dramatic silhouette that feels tailor-made for a villainous entrance. Beyond the demonic look, fans can also channel the Saja Boys’ K-pop alter ego with a costume inspired by Romance’s “Soda Pop” performance.

Your cat or dog may not know that HUNTR/X exists, but this purple braided pet wig makes them part of the cultural phenomenon. The headpiece is designed for small and medium pets and uses an adjustable elastic chin strap to help keep it in place. The purple braid gives it an unmistakable Rumi-inspired look without requiring your pet to wear a full costume. Highly recommended for a group photo.

If you’re dressing up as a KPop Demon Hunters character, you absolutely need to complete the look with this adorable Derpy candy carrier. The plush trick-or-treat bucket has soft faux fur fabric and is designed to hold Halloween candy while doubling as a character accessory.

A Rumi Halloween costume isn’t complete without her distinctive demon marks, which are sure to make you stand out at any party — especially a dimly lit one. These temporary tattoos offer an easy way to recreate the HUNTR/X singer’s signature patterns without committing to body paint. They’re also a more practical alternative, as they’re waterproof and can last for several days. The set includes three sheets of purple designs that glow under UV or blacklight.

Inflatable Halloween costumes became all the rage in the 2010s, thanks in large part to the hilarious T-Rex design. Now, Blue Tiger Derpy gets a go at this witty costume trend, bringing a goofy twist to the inflatable look. The oversized design for kids 7 and up is equal parts ridiculous and eye-catching, making it an easy choice for anyone looking to get laughs.

Although it’s for kids, I got my wife to squeeze into it (she’s 5 feet, 1 inch) and walk comfortably around our home, much to our cat’s confusion.

Skip the full costume and let Derpy do the heavy lifting. This oversized Blue Tiger head delivers the character’s goofy, deadpan look in one instantly recognizable accessory — ideal for a quick, low-effort costume.

I tried Derpy’s head on at the office and loved the mesh material on the eyes that allowed me to see all the funny stares I got from my colleagues.

The success of KPop Demon Hunters has turned the movie into something much bigger than a one-and-done streaming hit, with its characters, music and songs continuing to fuel fan enthusiasm long after its release. That momentum has translated into a growing wave of merchandise, costumes and accessories, and this Halloween lineup suggests the phenomenon is nowhere near slowing down.
