Best Group Costume Ideas for Friends in Ireland

When it comes to parties, festivals, or themed events in Ireland, nothing gets people talking like showing up in a group costume. From Halloween nights in Dublin to stag and hen weekends in Galway or even a themed birthday celebration, coordinated group outfits guarantee laughs, attention, and unforgettable photos.

The magic of going as a group is that you can share the effort, pool your creativity, and multiply the fun. If you’re planning your next big event, a Costume Shop Ireland is the perfect place to find ideas and inspiration. Here are some of the best group costume ideas for friends across Ireland, with options to suit every style, personality, and budget.

Classic Film & TV Ensembles

Everyone loves a throwback, and dressing as an iconic screen crew is an easy win.

Harry Potter Cast: Wands, robes, and a touch of magic make this a simple yet impressive choice. Think Gryffindor scarves, round glasses, and a lightning bolt scar or two.
Friends: A nod to the ‘90s sitcom still hits home. You can recreate Monica’s chef outfit, Joey’s “How you doin’?” vibe, or Ross’s leather pants fiasco.
Stranger Things: Retro ‘80s looks with scrunchies, denim jackets, and Hawkins High School tees are perfect for a bigger group. Add a Demogorgon mask for bonus points.

Irish-Themed Group Costumes

If you want to show some national pride while standing out, why not go for an Irish-inspired theme?

Leprechauns: A group of mischievous leprechauns with green hats, shamrocks, and maybe a pot of gold prop will always be a crowd favourite.
Riverdance Crew: Black costumes, wigs with curls, and dramatic Irish dance poses will get you laughs and admiration alike.
Irish Myths & Legends: Dress up as figures from Celtic folklore like Cú Chulainn, banshees, or faeries. This works brilliantly if you’re attending themed events around Samhain or Halloween.

Pop Culture Favourites

If your group wants something that feels modern and instantly recognisable, pop culture has plenty of options.

Squid Game Contestants: Green tracksuits and numbered shirts are easy to find and instantly identifiable. Add a guard in a pink jumpsuit with a mask, and you’ve nailed it.
Barbie & Ken Multiverse: With the Barbie movie still fresh in people’s minds, a group of Barbies and Kens in different outfits from cowboy Ken to rollerblade Barbie, will be a massive hit.
Taylor Swift Eras: Each friend dresses as a different Taylor Swift era, from country girl with cowboy boots to “Reputation” in black sequins.

Funny & Punny Group Costumes

For those who prefer humour, pun-based costumes are unbeatable in an Irish pub setting.

Ceilí of Condiments: Each mate dresses as a different sauce bottle, ketchup, mustard, mayo—perfect for a light-hearted night.
Snap, Crackle, and Pop: Great for a trio, with cereal box props to match.
Irish Weather Forecast: One friend is “sunny”, another “rainy”, another “windy”—together you’re a live Irish weather report (with guaranteed rain).

Easy & Budget-Friendly Options

Not every group has the time or money to invest in elaborate costumes. Luckily, there are plenty of quick wins.

Tourists in Ireland: Hawaiian shirts, oversized maps, selfie sticks, and socks with sandals. Easy to pull together and hilarious in a crowd.
Farmyard Animals: Onesies are cheap, comfortable, and available everywhere. Bonus: perfect for colder Irish nights.
Emoji Crew: Cardboard cut-outs of your favourite emojis strapped to your clothes make for a creative, budget-friendly choice.

Tips for Nailing Group Costumes in Ireland

Weather Proofing: Remember, Ireland’s weather can be unpredictable. If you’re planning to wear your group costume outdoors, say for a Halloween street event, make sure your outfits work with coats, umbrellas, or layers.
Plan Early: Popular costumes sell out quickly in Irish shops around Halloween and major festivals. If your group has its heart set on a theme, don’t leave it too late.
Add Props: Props like fake pints of Guinness, shamrocks, or themed accessories can really pull the look together.
Coordinate Colours: Even if everyone’s outfit is different, sticking to a consistent colour palette helps your group look united.

Final Thoughts

Group costumes aren’t just about the laughs, they’re about bonding, creativity, and creating memories that will last long after the party ends. Whether you want to lean into Irish pride with leprechauns and legends, keep it classic with TV favourites, or go modern with pop culture trends, there’s a group costume idea here for every set of mates.

So, next time you and your friends are heading out in Ireland for Halloween, a themed pub crawl, or a festival, get creative, coordinate your outfits, and enjoy the spotlight. After all, the best part of a group costume isn’t just the clever look, it’s the shared fun that comes with it.
