The best group Halloween costumes 

Ready to dive in? Here are ten group costume ideas that are bound to help you and your mates stand out. 

  1. Hocus Pocus 

Up first, we have the idea of transforming you and your pals into the iconic Sanderson Sisters: Winifred, Sarah, and Mary. Think corsets, flowing cloaks, and mismatched vintage fabrics. Oh, and don’t forget that each member of the witchy trio has her own signature colour. Winifred wears green, Mary wears red, and Sarah spooks in purple! 

For props, make a spellbook and grab some broomsticks, then have someone hold the iconic black flame candle. 

  2. Stranger Things 

How about stepping into the spooky town of Hawkins this October 31st? Whether you channel Eleven with her knee-high socks and signature bloodied nose, or rock a retro Hawkins High jacket like Steve, the Upside Down offers plenty of costume inspiration. 

From deadly Demogorgons and menacing Mind Flayers, to vintage windbreakers and walkie-talkies, the show blends the supernatural with a splash of 80s nostalgia. 

  3. The Wizard of Oz 

Bring a touch of fun to the party by dressing up as Dorothy and her friends for an instantly recognisable costume. Here’s what you’ll need to bring these iconic characters to life: 

  • Dorothy: A blue gingham dress and ruby red shoes. 
  • Scarecrow: Straw accessories, patchwork clothing, and a floppy hat. 
  • Tin Man: Silver clothes, shoes, and a funnel hat. You can easily DIY this with some cardboard and silver spray paint!  
  • Cowardly Lion: Faux fur ears, tail, and creative lion-inspired face paint.

While you won’t be scaring anyone with this group costume, it’s Halloween, so anything goes, right?

  4. Harry Potter 

Step into the wizarding world and dress up as your favourite characters from Hogwarts! Here are some essentials you’ll need for your magical makeovers: 

  • Harry: A wand, glasses, and the iconic lightning bolt scar. 
  • Hagrid: A huge overcoat, beard, and pink umbrella. 
  • Voldemort: White face paint, a black cloak, and Nagini snake prop.  
  • Hogwarts students: Get your wands, potion books, and house colours at the ready!

If you’ve got a bigger group, you could throw Hedwig and Dobby in the mix too. And if there’s still not enough costumes to go around, a few of you might have to take one for the team and show up as Muggles. 

  5. Ghostbusters 

When it comes to group Halloween costumes, it doesn’t get more iconic than the ghost-catching crew from Ghostbusters. Grab some matching beige jumpsuits, add name tags, and go as the legendary team this Halloween! You could make some DIY proton packs from boxes and tubing if you’re feeling crafty, and don’t forget to pick up some walkie-talkies to finish off the look. 

  6. Scooby-Doo

For a fun, nostalgic Halloween costume, throw it back to a childhood classic with Scooby Doo. For Velma, you’ll need an orange turtleneck, a red skirt, and her iconic glasses, and for Daphne a purple dress and green scarf will do. Eager to go all out? Add Scooby snacks, magnifying glasses, and a DIY mystery machine for the ultimate group photo op. 

  7. Music legends 

Get everyone to pick their favourite music icon and form the ultimate supergroup for one night only. Whether you’re into country or classic pop, there’s a legend for everyone to embody: 

  • Elvis: Slicked-back hair, sideburns, and an iconic flared jumpsuit.
  • Bowie: Lightning bolt makeup and glam-rock fashion. 
  • Dolly Parton: A blonde wig and rhinestone everything! 
  • Elton John: Oversized sunglasses and all the feathers and sparkle you can find. 
  • Stevie Nicks: Flowy black layers, lots of lace, and mystical, witchy vibes. 

  8. Spooky circus

Next on our list of group Halloween ideas we have a spooky circus theme. Think haunted carnival meets horror with a twisted troupe of terrifying clowns and creepy jesters. You’ll need bold stripes, Harlequin diamonds, top hats, tailcoats, and more. And for a mystical touch, have someone carry a crystal ball and fortune-teller cards. 

  9. Haunted fairytale 

Why not give some fairytale characters a spooky makeover this Halloween? We’re thinking a blood-stained Little Red Riding Hood and a ghostly Snow White, not forgetting Cinderella with a torn blue dress and broken crown. You could add in an evil stepmother for dramatic effect, then tie everything together with storybooks, cracked mirrors, and wilted flowers. 

  10. Classic ghosts 

Looking for group Halloween costumes that are super low effort? Keep it simple this year and rock up as a squad of ghosts. Just find some white sheets, cut out some eyeholes, and you’re good to go. For an extra touch of spookiness, have everyone carry a flickering LED lantern (ominous vibes without the obvious fire hazard). Budget-friendly and super easy to pull off, this costume is a guaranteed winner. 

Whether you’re hosting a Halloween party at home or planning a spooky night out, hopefully you’re now feeling confident that you can absolutely nail the group costume!
