7 Unique Group Costume Ideas for Your Next Halloween Bash
Group costumes fail for one reason: somebody cannot find their piece. The theme is great, four people are in, and the fifth person spends two weeks hunting for a costume that does not exist in their size. So this list is built differently. Every theme here is one we can outfit from stock, for kids and adults and sometimes the dog, so the whole group can order from one place and show up looking like they planned it.

1. The Marvel team
The easiest group theme because everyone gets a different hero and they all still match. Spider-Man, Captain America, Black Panther, Iron Man, Deadpool, Scarlet Witch, Ghost Spider, and Shuri are all in stock across kids and adult sizes, and there are half masks and gloves for anyone who wants in without a full suit. Even the dog has a Captain America costume. Start at Marvel licensed costumes.
2. Star Wars bounty hunters
The Mandalorian, Boba Fett, Darth Vader, stormtroopers, Ahsoka, and Princess Leia, with Grogu for the smallest member of the group. Kids' value versions include a jumpsuit and molded mask and are hand wash cold; adult Qualux versions add padding and detail. Browse Star Wars licensed costumes to line up sizes for everyone.
3. The food truck
Our most-photographed group theme. Everyone is a menu item: hot dog, taco, pizza slice, banana, chicken sandwich, bucket of fried chicken, beer stein. The Adult Banana on Hanging Display Card is the default for anyone undecided at $31.99 at time of writing, and couples sets like hot dog and bun or taco and lime split neatly between two people. Tunics fit over clothes, so this theme is also the warmest. See it all in Food and Beverage costumes.
4. The Belcher family from Bob's Burgers
A group of four or five who like the show can do this for very little. The Tina Costume includes the dress, foam wig, and glasses ($18.99 at time of writing), the Louise costume has the green dress and pink bunny ears, and there is a Linda spice rack prop. Bob is a white T-shirt, an apron, and a mustache; Gene is a yellow shirt and a keyboard. Officially licensed, and our Bob's Burgers collection has the details.
5. Super Mario Bros.
Mario, Luigi, Princess Peach, and Yoshi cover a group of four with room for a Toad in a mushroom hat. The Boy's Mario Costume includes the jumpsuit, red hat, and self-adhesive mustache, Luigi comes in boys' and toddler sizes, and Peach is available from toddler to women's XXL with a matching accessory kit of gloves and crown. It is one of the few themes where kids and adults can be the same characters.
6. Among Us crewmates
For the gaming crowd, a row of inflatable crewmates in different colors is instantly recognizable and very funny in person. The Adult Inflatable Crewmate Costume is lightweight, runs on a battery fan (4 AA batteries not included) that keeps you cool, seals with elastic at the ankles and arms, and fits heights from 5' 10" to 6' 6". Buy one per person in different colors and let someone be the impostor.
7. The Minecraft server
Steve, a Creeper, an Enderman, and an Ender Dragon make a blocky, kid-friendly group. The Kids Minecraft Steve Pop-Out Costume uses a lightweight wire frame for the square look, adults can wear the Steve vacuform mask over a teal shirt and jeans, and the Creeper headpiece unfolds into a complete cube that fits over your head. Everything is in our Minecraft collection.
Making the group work
- Pick a default. Every theme needs a costume for the person who cannot decide. Banana. Crewmate. Stormtrooper.
- Check sizes before announcing the theme. Our collections filter by age group, so confirm the theme covers everyone first.
- Order together. One order over $99 ships free with standard shipping, and peak-season processing takes 24 to 72 hours, so place it at least two weeks out.
- Take the group photo early, before anyone takes off a headpiece.

Frequently Asked Questions
What is the best group costume theme for mixed ages?
Star Wars and Marvel cover the widest range of sizes in our store, from toddler to adult, with dog costumes too. A food truck theme also works for every age because tunics fit over regular clothes.
How do we handle a group member who cannot decide?
Choose a default costume for the theme before you start, such as a banana for a food theme or a crewmate for a gaming theme, so undecided members have an easy answer.
Are inflatable costumes hot to wear?
The inflatable crewmate costume has a built-in battery fan that keeps air moving, and the product page describes it as lightweight and comfortable. It needs 4 AA batteries, which are not included.
When should a group order Halloween costumes?
At least two weeks before the party. Peak-season processing takes 24 to 72 hours, ground shipping typically arrives 3 to 5 business days after shipping, and popular sizes sell out.
