This year’s biggest movies and shows have handed Halloween shoppers an unusually strong lineup to pull from — a demon-hunting K-pop trio with officially licensed costumes, a witch duo returning for a second year running, and a mythological epic that’s already shaping up as a go-to group theme. Whether you want something you can order today or something you can build from your own closet by tonight, here are 10 costume ideas pulled straight from what’s actually trending this October.
10 Costume Ideas From This Year’s Movies & TV
1. HUNTR/X Trio (Rumi, Mira, Zoey) — KPop Demon Hunters
Netflix’s animated hit produced the single most in-demand costume of the season, and it’s officially licensed: Spirit Halloween sells Rumi, Mira, and Zoey looks in both kids’ and adult sizes, right down to Rumi’s yellow jacket and lace-up boot covers. Our take: this is the best group costume on the list by a wide margin — it only works as a trio, so round up two friends before the good sizes sell out again.
2. Elphaba & Glinda — Wicked: For Good
With the second film now streaming, the green-gown-and-witch-hat versus pastel-pink-and-tiara pairing is an easy, instantly recognizable duo costume. The “For Good” era adds subtle purple-and-silver streaks to Glinda’s look if you want to signal you’ve seen the sequel specifically. See our full guide to where Wicked: For Good is streaming if you need a refresher on the look before you shop.
3. Agamemnon, Odysseus & Athena — The Odyssey
Christopher Nolan’s mythological epic has made ancient-Greek armor one of this year’s most-searched group themes. Gold breastplates, capes, and a simple laurel crown go a long way, and it scales from a solo warrior look to a full trio if you can rope in two more people for Odysseus and Athena. Our take: the most flexible costume here — do it alone, as a pair, or as a group without changing the core pieces.
4. Wednesday Addams
Still one of the most reliable costumes two seasons into Netflix’s series: a black dress with a white Peter Pan collar, tightly braided pigtails, and a flat, unimpressed expression do all the work. No props required, which makes it one of the few genuinely low-budget options on this list.
5. Joanne & Noah — Nobody Wants This
For a couples costume with more personality than the obvious picks, go with podcaster Joanne and rabbi Noah from the show’s just-arrived third season: a casual blazer-and-jeans look paired with a simple dark suit and a yarmulke communicates the pairing instantly to anyone who watches the show, without needing a single matching prop.
6. Cyclops & Jean Grey — X-Men
The red visor and yellow-and-blue uniform remain one of the most recognizable comic-book silhouettes around, and Jean Grey’s look pairs naturally alongside it for couples who want something more comic-accurate than this year’s film costumes. Our take: best for anyone who already owns the pieces from a past con or costume box — buying both looks new gets pricier than most entries on this list.
7. Sabrina Carpenter
A sparkly mini dress, exaggerated winged eyeliner, and a bouncy high ponytail get you most of the way to a recognizable Sabrina Carpenter look without needing an exact outfit match. It’s forgiving enough to build from pieces already in your closet, which keeps it near the top of easy, budget-friendly picks this year.
8. Charli XCX “Brat”
Lowercase text on a plain, bright lime-green top (or just a lime-green background held up as a prop) is the entire costume, and most people will recognize it instantly. This is our pick for Easiest Last-Minute Costume — you can realistically put it together in under 20 minutes with things you already own.
9. Shane Hollander — Heated Rivalry
For the sports-drama crowd, a simple hockey jersey over practice gear nods to the show’s rival-rink romance without requiring anything you can’t grab from a sporting-goods store. Pair it with a partner in a rival team’s jersey for an easy, low-effort couples angle.
10. A Red-Carpet Glam Look
Not every costume needs a specific character. A metallic slip dress, statement jewelry, and oversized sunglasses channel the general “celebrity arriving at a premiere” energy that’s been all over entertainment feeds this awards-adjacent season — an easy option if nothing character-specific appeals to you but you still want to dress up.
Best Group Costume & Easiest Last-Minute Pick
If you’re coordinating with friends, the HUNTR/X trio is our top group pick — it’s the single most talked-about costume of the season, officially licensed, and immediately recognizable even to people who haven’t seen the film. If you’re starting from scratch the night before, the Charli XCX “Brat” look is the fastest, cheapest option on this list and still reads instantly at any party.
