Costume Ideas for Groups of 4: Three’s a Crowd, Four’s a Party [Costume Guide]

"What are you gonna be for Halloween?" It's a hard enough question to answer for yourself sometimes, but it can be nearly impossible to decide when you are looking for Halloween costume ideas for friends, or perhaps a family of four. But you have to think of all the advantages that go with a group costume: awesome photo opportunities that are sure to be good enough for a picture frame (or Facebook profile picture), you'll be a shoo-in for costume contests, and you'll never lose your friends or family at a crowded Halloween party. Still not sure what to dress up as? Don't fret, we here at HalloweenCostumes.com have put together an awesome guide to help you find group costume themes with enough characters for a group of four!

Descendants Costumes

The teenagers of Disney's most infamous villains returned in 2019 with Descendants 3. Evil Audrey was added to the lineup, rounding out a perfect group of four costumes. Sure, some of them are villains in the movies, but they're all friends in the end. So why not head to the Isle of the Lost for a Halloween you'll never forget. These Disney Descendants costumes are a hit with the teen crowd!

Frozen Costumes

Elsa took us by storm in 2013 with the release of Frozen. And with Frozen 2 released in 2019, you can bet that storm continues. Join the sensation by going as Anna and Elsa and the rest of the gang with this family Halloween costume idea. We may not know what their next story will be, but you can have an epic journey with these Frozen costumes for four! You can even add the family pet with an appropriately-themed pet costume. How cool is that?

Fortnite Costumes

Fortnite remains one of the hottest games out there, so of course, we've got Fortnite Halloween costumes perfect for groups of 4. Whether you're planning on trick-or-treating as a Skull Trooper or Cuddle Team Leader, HalloweenCostumes.com has you covered. We also have alternate versions of many of these costumes, so be sure to check out our full range of Fortnite costumes. Don't forget to thank the bus driver!

1920s Costumes

There are tons of great historical costume ideas perfect for a group setting, but there's nothing quite like 1920s America. Beneath all the glitz and glamor of the flappers with men in boater jackets on their arms, there was mafia corruption, women striving to find their political voices and children making a living selling the news. There are plenty of 1920s costumes to reflect the times, whether you're looking for sparkly flapper dresses or seedy gangster outfits. Historical costumes like these are wonderfully versatile, as you can use them for Halloween, decade-themed parties and even your child's history class presentations!

Back to the Future Costumes

Great Scott, these Back to the Future costumes make the perfect group of four family costumes. With Doc Brown and Marty, the night is sure to be an adventure no matter the year you're in. As they say, "where we're going, we don't need roads." And you don't need roads to find Back to the Future Halloween costumes online, although they're helpful to get the packages delivered. While this is a great 80s costume idea, there are certainly others fit for a group of 4 fabulous people!

The Wizard of Oz Costumes

Ah, can you think of a more classic movie foursome than the main characters in The Wizard of Oz? (The Wizard of Oz is one of the best group costume themes out there!) Follow the yellow brick road to your Halloween party as Dorothy, Scarecrow, the Tin Man (or Woman), and the Cowardly Lion. Look through more of our Wizard of Oz costumes and decide what works best with your group. Are you looking to create a family group for 4? Is your squad more interested in being as movie accurate as possible? Don't forget, if you're feeling more sinister for the holiday, you could also go as a pack of four flying monkeys.

Alice in Wonderland Costumes

Going in four Alice in Wonderland costumes works perfectly for a group. There's a balance between men and women characters in the story, and they're all equally exciting and crazy, so no one will feel like they got ‘the boring one'. Your group could dress as Alice, the White Rabbit, the Red Queen, and the Mad Hatter. There are more Alice in Wonderland costumes to choose from, too! If your group is a fan of Disney movies, remember that Alice in Wonderland is a Disney movie! Feel free to check out our other Disney costumes if you're looking for more Disney group costume ideas for four people.

Vikings Costumes

Become the legendary Norse hero Ragnar Lothbrok and his crew as you raid England to become a King. The History Channel's Vikings, inspired by the saga of Ragnar, makes the perfect group of four costumes for those looking for a more rugged and dangerous costume idea. Not as familiar with the show? You can still wear Viking costumes and create your own group.

Teenage Mutant Ninja Turtles Costumes

If you're feeling particularly retro this Halloween, you and your group of four might want to consider going as the Teenage Mutant Ninja Turtles. (Admit it, you knew that TMNT would be in a list of costume ideas for 4 people!) This crime-fighting quartet covers all the basic personality types: the leader, the silly one, the geeky one, and, well…the crabby one. (Just make sure that you know who is who between the colors of your masks and pads.) Does this fit your Halloween group? Awesome! Grab a pizza and head out, your group costume idea is set! 

Animal Costumes

Get in touch with the animal kingdom by dressing as a group of cute creatures! Pick your favorite critter and create your own group of 4 costumes. Your mood can dictate how the night goes in this group costume idea: your group of 4 can be sweet and cuddly, or you can bare your fangs in a lion costume and show off your claws. Take a peek at all of our animal costumes to decide which suits you and your group quartet best.

Fantasy Costumes

Fantasy and mythical creature costumes are another one of those great family costume ideas. Think about it, they're alluring and unique. Which is how your family is to you, so it makes perfect sense! You can find everything from baby and toddler to adult plus size costumes, so there's really no excuse to leave this idea sitting around. If you want to make it more of a cohesive group theme, maybe you can think of all those critters that have horns or wings. There's bound to be one group of mythical creatures that your family loves and wishes were real.

Superhero Costumes

A superhero theme can fit so many different superhero groups—The Avengers, the Justice League, the X-Men, Teen Titans and more! Would you like to get a couples' costume? Then you can go out with your best friends and rock the town as a team of superheroes. Is your group a family of famous crimefighters like the Incredibles? Buy a superhero costume online and you might just save Halloween!

Horror Movie Costumes

Horror movies are usually enjoyed around Halloween time, so why not wear a few of your favorite horror movie character costumes as a group? There are plenty of Pennywise costumes, Chucky outfits and Ghostface getups to go around, so you have some flexibility depending on who wants to be which character. You can even don a few zombie costumes if you don't want to be part of any specific horror movie. Don't forget to take lots of pictures to remember all the fun you had on Halloween!

Mean Girls Costumes

"That's so fetch!" We mean these officially licensed Mean Girls costumes, of course. Grab your girlfriends and create the famous Plastics group of 4. Go as their famous sexy Halloween costumes (with one scary one), or grab a bunch of sexy Santas and mimic their Jingle Bell Rock all night long. You'll be ruling the school in no time with these fabulous movie costumes! (Just remember to wear pink on Wednesdays.)

Sports Fan Costumes

Not really interested in movie character themes? Do your favorite movie character costumes end up being A League of Their Own costumes or related to another sport? Is your Halloween group more into going to the stadium than the movie theatre? Perfect! Hit your Halloween party as a pack of athletes. You and your friends could go as racecar drivers, baseball players, boxers, basketball stars, football quarterbacks, golfers, or even a referee. We have a ton of sports costumes to choose from, so everyone can find a uniform from their favorite sport.

WWE Costumes

Want to step into the ring and deliver a crushing move to your biggest rival? Then you should grab some friends and these officially licensed WWE costumes to make the ultimate wrestling group. There's even a WWE makeup kit so you can get the look just right.

Super Mario Costumes

Dress as characters from Super Mario Bros and reenact your favorite party games with your group of four this Halloween! Or better yet, throw your own Mario party for the holiday, complete with a go-kart track in the backyard and a selection of mushrooms and shells to use as party favors!

Sailor Moon Costumes

"In the name of the moon, I'll punish you!" If you're planning on wearing a Sailor Moon costume, you're going to want to remember her signature phrase. Get some gal pals together as Sailor Mercury and Sailor Mars for extra girl power. But if you really want to round out your group of four, you're going to need a Tuxedo Mask. He is Usagi's main squeeze, after all! These anime costumes are perfect for cosplaying at anime conventions as well as dressing up for Halloween outings, so you have more excuses to wear them throughout the year.

KISS Costumes

KISS is one of rock's most famous quartets—which means if you dress up in these celebrity costumes for Halloween, you and your group of four will be the most famous guests at the party! And, we all know KISS's party anthem, which will help you bring excitement to any place you go, all night and every day. Go all out and dress in full, authentic KISS gear to really impress your friends.

Grease Costumes

The perfect group costume for mixing and matching, the characters from Grease allow you to create a great group or family costume. The Pink Ladies and T-Birds jackets make for the perfect combos—and if you don't want to dress as one of them, you can don a Rydell High Cheerleader costume or go as Frenchy or bad Sandy. (Or perhaps find other 50s costumes for a decade-themed party!) Be sure you know some lines from "Greased Lightnin'" and "You're the One That I Want" since you'll be singing all night in these Grease costumes!

Batman Villain Costumes

It's so good to be bad. Few superheroes have as colorful a Rogues Gallery as Batman. From the crazy antics of the Joker and Harley Quinn to the quizzical conundrums of the Riddler, few group costumes will be as recognizable on Halloween. One of the more iconic Batman stories is even called The Long Halloween—so get your crew together and cause some havoc! You can see all of our Batman costumes, hero and villain alike, in our store.

Game of Thrones Costumes

Not all fantasy and fairy tale stories have friendly fairy godmothers and happily ever after endings. If you're more of a dark fantasy fan, perhaps the gritty fantasy world from Game of Thrones appeals to you. There are certainly a great number of characters perfect for having a group of Game of Thrones costumes, and you can even fill in spaces with the kids as dragons or direwolves. This group cosplay idea is also great for adult fans who want to attend a nerdy convention in costume!

The Addams Family Costumes

"They're creepy and they're kooky. Mysterious and spooky. They're all together ooky. The Addams Family!" Do we need to keep going? The Addams family makes a great 'creepy but not too scary' family costume idea for four people. Your family will be the envy of everyone on the block with these group Addams Family costumes.

Hocus Pocus Costumes

We suggest forming a calming circle before freaking out about how cute your girl squad will look in these Hocus Pocus costumes. (After all, these aren't your typical witch costumes.) The Sanderson sisters make a perfect group of three costumes, but you can stretch it to a group of four with a black cat costume, or even a Billy Butcherson costume! Many adult black cat onesies are unisex costumes, so whether your squad is comprised entirely of ladies or if you have a man in the mix, you'll be ready to run amok.

Beatles Costumes

Beatles Costumes

One of the most iconic groups of 4 guys is, of course, the Beatles. (Also known as the Fab Four!) Grab a few of your buddies, wear these iconic gray outfits and make the ladies swoon. You probably won't get mobbed by ladies like the Beatles used to be, but you could still put on a show with some karaoke. These iconic 60s-70s costumes are sure to hit all the right notes!

Spider-Verse Costumes

Spider-fam, Spider-fam! After watching Into the Spider-Verse, you might have been bitten by the Spider-Man bug. Why not get the entire family involved by wearing Spider-Man costumes? Characters like Miles Morales and Spider-Gwen are certainly favorites kids' costumes, so this is one four-person family costume idea that everyone will love!

101 Dalmatians Costumes

While a group of 101 Dalmatians costumes could easily accommodate a gathering of any size, this costume idea works really well for a family of four. Mom makes an excellent Cruella, but you can always mix it up and have toddler costumes paired with your adult costumes, too! Everyone else gets to be dalmatians, unless you can DIY some Horace and Jasper outfits. (We have faith in you!)

Ghostbusters Costumes

Who you gonna call? Ghostbusters! Here at HalloweenCostumes.com, our Ghostbusters costumes come in all shapes and sizes, so any of your family members can be whatever character they want to be. You can even have all four Ghostbuster characters for mom, dad and the kids. (Maybe even throw in the family pet as a ghost?) Once you're all ready in your Ghostbusters outfits, you'll be more than prepared to bust some ghosts!

Scooby-Doo Costumes

The Mystery Machine gang is on the case! Scooby-Doo costumes are great for groups of four people, whether you want to be all 4 of the human characters or have Scooby in your squad instead. Just make sure you solve that mystery! Of course, there are plenty of Scooby-Doo costumes for kids as well as for adults, so you can always turn this group idea into a family costume, too.

Peter Pan Costumes

Your child might not want to grow up, so why not try out this Peter Pan group costume idea? With classic characters like Peter Pan, Captain Hook, Wendy, Smee, Tinkerbell and others, you can feel Neverland-ready on Halloween. Maybe you could even add a crocodile costume to your group, or some pirate costumes to give Captain Hook a full crew. This squad costume is great because it can accommodate a group of any age or gender. There are so many ways to dress up!

Toy Story Costumes

To Infinity and beyond! Toy Story is one of the best and most beloved Pixar franchises, with tons of cool character costumes—including inflatable costumes! Whether you enjoy new characters like Duke Caboom and Gabby Gabby or classics like Buzz and Woody, we have all of the Toy Story costumes your group could want. You know that you're going to make everyone jealous when your gang shows up dressed in these Pixar costumes!

The Price Is Right Costumes

Your group will win big when you wear these The Price Is Right costumes. These unisex costumes are great for any group, and you'll love taking silly pictures with everyone. Sure, your score may not look great, but that can change at any time. No matter which color you end up with, just know that you're all winners when it comes to this funny group Halloween costume idea!

Flintstone Costumes

If you're a couple of couples looking for the perfect double couples costume idea, look no further than these Flintstones costumes! These stone-age neighbors are always competing, but in a fun and friendly way. There are also a few other characters like Dino, Pebbles and Bam-Bam if you'd like to switch things up, too!

Harry Potter Costumes

Create your own magic when you wear any of these Harry Potter robes. (And don't forget costume accessories like wands and glasses.) You can represent any of the four houses! We also have plenty of other Harry Potter costumes for some of your favorite teachers and students. While these book costumes would be great for a group of four, they can accommodate a group of any size. Get ready to attend the wizarding world of Harry Potter as any number of your beloved characters!

Nightmare Before Christmas Costumes

If your family can't decide between spooky and kid-friendly, why not do both? Nightmare Before Christmas is a timeless Halloween movie classic, filled with loveable characters and child-approved spooks. These Halloween movie costumes are also instantly recognizable, so much so that you might get pulled aside and asked for pictures! Don't forget to take your own family photos to share on social. #ThisIsHalloween

Circus Costumes

Be the family circus with our large selection of circus costumes! Whether you're more of a traditionalist or you'd like to mix it up with some dark circus costumes, there are so many roles for your group to play! Choose any one of several ringmaster costumes, strongmen, lions, clowns and more. You can even add the family dog into the mix with a tutu if they're great at tricks!

Space Costumes

There are so many great costume themes and ideas that don't depend on TV and movie knowledge. Take these outer-space costumes, featuring a mixture of astronaut costumes and alien costumes! Maybe your family of 4 went on a space expedition and found alien life, or you're actually a family of aliens trying to blend in with the rest of us Earthlings. You can even do a mix of both to make it more fun. We just hope you invite us on your latest space adventures! 

Fairy Tale Costumes

There are so many storybook characters that would work well for groups of 4 costumes for Halloween. You have the classic Goldilocks and the Three Bears, but you can always add other iconic characters like Red Riding Hood and the wolf. But, you don't have to stop with Little Red Riding Hood costumes and Goldilocks—classics like The Three Little Pigs, Hansel and Gretel and others are waiting for your personal touch.

Universal Monsters Costumes

What do vampire costumes, Frankenstein costumes, werewolf costumes and mummy costumes have in common? They're all part of the Universal Monsters gang! If your family loves to flip on flicks from yesteryear as part of your Halloween festivities, perhaps a Universal Monsters group costume idea is perfect for you. These cryptid creatures fit in perfectly with Halloween festivities, and you can be just a bit creepy without making the neighborhood kids run for cover. Don't forget to grab your vampire fangs, costume makeup and other Halloween essentials to make your costume feel complete!

Care Bears Costumes

Are you looking for warm, cuddly costumes to wear on a chilly Halloween night? There's nothing quite as soft and comfortable as a Care Bears costume. The best part is that there's a ton of characters to pick from, so even your pickiest family member can get the character they want without doubling up. (Or do have multiple—we'd love to see a group of Grumpy Bears!) It's honestly hard to be grouchy when faced with such a cuddly Halloween costume group idea.

PJ Masks Costumes

If you're a parent with young children, there's a good chance that you're familiar with PJ Masks—and your kids may want to wear PJ Masks costumes for Halloween! They'll certainly look cute as Owlette, Catboy or Gekko, but why let your kids have all the fun when you can join in? (After all, what's a superhero without their trusty team?) It's time to be a hero!

Dragon Ball Z Costumes

If you like exercising, screaming at the top of your lungs and having your hair change colors, you were probably already considering finding some Dragon Ball Z costumes for you and your friends. We have quite a few character options available at HalloweenCostumes.com, so hopefully you won't have to fight your friends to wear your preferred costume.

Thor Costumes

If you're looking for Marvel group costume ideas, why not take some inspiration from Thor: Love and Thunder? There's the Jane Foster Thor armor, of course, and Gorr's toga-ish getup. But we also loved the giant screaming goats and that Halloween party flashback. (We are a Halloween costume company, after all!) To reenact those scenes, you'll want to start with a Thor costume. Add a hot dog costume and you'll have the Halloween flashback down. For the scene-stealing goats, rest assured that we carry goat costumes from toddler through plus size, so all you need to work on is the scream. Just remember to take it easy and hydrate or you'll find yourself becoming a little horse instead!

When it comes to Halloween, the sky is the limit! There are so many things you can be in your group of four: animals, zombies, musicians, cops & robbers, dinosaur costumes, the Flintstones, movie characters, bugs, cartoon characters, pirates and more. Another fun idea would be to pick a color and base all your costumes around that, or pick separate colors for a rainbow-themed costume group. Be sure to look through our group costumes to see what else we've come up with and hopefully it'll give you some inspiration. Once you have the perfect group costume set, you can focus on the most important thing: having fun. The more the merrier!
