With Halloween slowly approaching, it’s time to prepare some elaborate outfits. However, you know what people say— the more, the merrier! Round up your squad and give these best group Halloween costume ideas a try.

1. K-Pop Demon Hunters

If you need a recognizable three-person Halloween costume, the K-pop Demon Hunters’ Rumi, Mira and Zoe are a definite must. Their character designs are absolute bangers, whether it’s from their first performance or their Golden outfits. Plus, it’s still pretty popular, with the movie having garnered 628.2 million views since its premiere as of June 1, 2026. 

2. Powerpuff Girls

Another three-person option is to have the Powerpuff Girls! While they only ever really have one outfit, you can do a reinterpretation of what they would look like in real life. As long as you stay true to the classic pink, green and blue, you’ll surely end up recognizable. And if you have extras, you can tag in villains like Mojo Jojo and HIM in. 

3. Totally Spies

Childhood heroes Clover, Sam and Alex are iconic in their colorful bodysuits and studded heart belts, making it a fantastic addition. If you’re four or five in the group, you can have one cosplay as Britney in a blue bodysuit and Mandy in a purple bodysuit, respectively. 

4. The Ghostbusters

Who you gonna call? Ghostbusters is simply a classic group Halloween costume idea, no matter how many people are in the group. While the suits and gear make it obvious enough, you can get a few ghostly balloons to add gravitas and help people connect the dots.

5. Addams Family

If you’re spending Halloween with the family, consider the Addams Family! The characters are pretty simple to dress up for. For instance, Wednesday Addams only needs her braided pigtails, a black dress and a white-collared shirt. With Morticia Addams, a black dress with bell sleeves and a moody lipstick is all you really need. 

6. The Classic Horror Movie Killers

If you’re seeking a five-person Halloween costume, assemble the most iconic slashers known to television. Imagine going down the street to see Michael Myers, Freddy Krueger, Leatherface, Jason Voorhees and Ghostface? Petrifying. 

7. The Spider-Man Multiverse

If you want a more feel-good option where people will actually rejoice when seeing you, choose a superhero. Or multiple versions of the same superhero. There are so many Spider-Man variants to choose from, from Miles Morales’ Spider-Man to Tom Holland’s Spider-Man to even Spider-Gwen!

8. The Greek Gods and Goddesses

Greek gods and goddesses deserve the spotlight, especially with how you can definitely modernize their overall look. Like, imagine an Aphrodite in a white coat with rose petals all around her, or an Artemis with a fur top? Stunning. 

9. The Stranger Things Squad

Stranger Things has many iconic costumes, from the Scoops Ahoy costume to the Hellfire Club T-shirt. Even Eleven’s pink dress and blonde wig are a total moment. Assemble the squad and let people take their picks. 

10. Scooby-Doo Group

Another well-loved yet always welcome Halloween group costume is the Scooby-Doo gang. Velma and Daphne get so much love, but Fred, Shaggy and Scooby are also more than memorable and relatively easy to cosplay with the right clothing pieces. 

11. The Wicked Team

There’s so much love for Glinda and Elphaba ever since the movie adaptations came out, making them a fun group costume idea alongside Fiyera, Nessarose and Boq. However, if you need more options, you can also introduce Dorothy and crew just like how Wicked: For Good did.

12. The Winx Girls

The Winx are such a vibe, especially with so much media like shows and games still coming out for the newer generations. Round up your five favorite girls and take your pick of which of the six each one should dress up as on Halloween. 

13. The Disney Princesses

If there’s more in the group, consider pivoting to the Disney princesses. There are many more options, especially with the newer ones like Rapunzel and Moana. Couples can also take their pick between couples like Tiana and Naveen or Cinderella and Prince Charming.

14. The Family Madrigal

Encanto’s Madrigal family had so many fun character designs that were certainly recognizable. Choose your favorites and round up your own family to cosplay them. You could also just call in your siblings to do at least Mirabel, Isabela and Luisa.

15. The Disney Villains

Take an evil turn and look out for Disney villain costumes instead. Whether it’s the iconic Ursula, the evil Maleficent, or the fashionable Cruella de Vil, there’s much to choose from. Just remember to coordinate to avoid any double trouble.

16. The Witchy Coven

Dressing up as witches has forever been great and iconic. However, if you want a little more guidance on what to look for, consider Agatha Harkness’ Coven from the Agatha All Along series. You could even sing the Ballad of the Witches’ Road and wait for the road to pop up. 

17. The Taylor Swift Eras

The different Taylor Swift eras would be the perfect group halloween costume inspiration, especially with how iconic each one is. Each one is color-coded, too, with its own iconic look, like the Lover bodysuit from the concert tour or the Speak Now purple dress. 

18. The Barbie Professions

Another simple but fun idea is to feature different Barbie characters and professions, similar to the depiction in the Barbie live-action film. Aside from being all dressed up, it’s simply a great way to celebrate women. Dibs on becoming President Barbie!

19. The Mean Girls

While October 31 may not land on a Wednesday, you can definitely still wear and flaunt your best pink outfits to channel your inner Mean Girl. If you’re four in the group, it’s perfect to cosplay Regina George, Cady Heron, Gretchen Weiners and Karen Smith.
