Group fancy dress works best when everyone picks from the same theme without matching outfits exactly. These twelve costumes cover superhero squads, character line-ups and a few inflatable crowd-pleasers, so a group of any size can coordinate in minutes.
How we chose: we favour costumes that come in a men's and women's version, or work for anyone regardless of size, so a mixed group can shop from one theme. Each pick links to its product page and shows what it is best for and a rough price band, so you can choose fast.
Superhero squad
Supergirl
A red and blue jumpsuit with the House of El crest, easy to match with a Superman or Wonder Woman in the group.
Wonder Woman
The classic red, gold and blue costume that anchors a DC group photo whatever else people wear.
Superman
A padded muscle-effect jumpsuit with cape, built to pair with the group's Supergirl or Wonder Woman.
Light-up skeleton
A glowing bone-print jumpsuit that reads as its own thing in daylight and lights up once the group heads out at night.
Character line-up
Ghostbusters (kids)
A boilersuit with an inflatable proton pack, so the youngest members of a family group get their own Ghostbusters look.
Ghostbusters (adults)
The matching adult boilersuit and inflatable backpack, easy to multiply across as many group members as you need.
Mario and Luigi
A bodysuit and cap set covering both brothers, so two people in the group can peel off as their own pairing.
Where's Wally
The red and white stripes make this one instantly readable in a group photo, and it works for any gender.
Funny inflatable crew
Inflatable T-Rex
A blow-up dinosaur suit that turns one person into the group's built-in punchline, no coordination required.
Inflatable ride-on horse
A blow-up horse and rider costume built for two, ideal if part of the group wants their own side act.
Inflatable shark duo
A two-pack blow-up shark costume that works as a stand-alone joke or slots into a beach or ocean theme.
ABBA disco set
A 70s dress, wig and accessories kit built for a foursome, perfect if part of the group wants a disco theme instead.

Frequently asked questions
What is the easiest way to plan a group fancy dress costume?
Pick one theme with room for different roles, such as a superhero team or a set of characters, so everyone has a distinct look without needing to match exactly.
How many people does a group costume need?
Anywhere from three upwards works. Themes like a superhero squad or character line-up scale easily because you can keep adding a new character.
Can group costumes work for mixed sizes and genders?
Yes. Most of these picks come in separate men's and women's versions, and the inflatable options are one-size, so a mixed group can shop the same theme.
