28 Trendy Group Halloween Costume Ideas for Women That Will Win Every Party

Group costumes are basically the best part of Halloween. You get to coordinate with your favorite people, show up somewhere looking like an actual squad, and skip the stress of figuring out a solo look that has to carry the whole night on its own. If you and your friends are already texting “what are we doing this year,” consider this your idea bank.

Below are 28 trendy group Halloween costume ideas for women that will win every party, whether your crew is three people or twelve, whether you want something cute and colorful or a little more clever. Most of these can be pulled together with pieces you already own, a few thrift store finds, and maybe one Amazon order.

Decades Squad: 70s, 80s, 90s, and 2000s

Each person picks a decade and goes all in. Think bell bottoms and fringe for the 70s, neon windbreakers and scrunchies for the 80s, slip dresses and butterfly clips for the 90s, and low-rise jeans with a rhinestone belt for the 2000s. It’s an easy concept to explain to strangers at the party and gives everyone room to express their own style within the theme.

Spice Girls

This one never gets old because it works for any group size and every personality has a natural fit. Baby Spice in a pastel mini dress, Scary Spice in animal print, Posh in a sleek little black dress, Sporty in a tracksuit and sneakers, Ginger in a Union Jack moment. Thrift stores are goldmines for this one in September and October.

Wizard of Oz Crew

Dorothy in gingham with ruby red flats, plus Glinda, the Scarecrow, Tin Man, Cowardly Lion, and even a Wicked Witch if you have enough people. This is a costume that reads instantly in photos, which matters more than people think when half the night is spent taking pictures anyway.

Bratz Dolls

Big lips, bigger hair, and a whole lot of glam. Bodycon dresses, chunky platform shoes, and heavy eye makeup make this one of the most fun group looks going around right now. It photographs incredibly well under party lighting too.

Flower Bouquet

Everyone wears a different bright color and adds petal-shaped accents, whether that’s a headpiece, a skirt cut into petal shapes, or just a monochromatic outfit in their assigned color. Stand together for a photo and you genuinely look like a bouquet. Simple concept, huge visual payoff.

Barbie and Her Friends

With the Barbie movie still very much in the cultural bloodstream, this one has real staying power. Pink dresses, matching accessories, maybe one person as Ken for comedic balance. Zara and H&M both tend to stock pink pieces heavily this time of year, so shopping is easy.

Mean Girls: The Plastics

Pink on Wednesdays, obviously. Grab a pink top, a plaid mini skirt, and gold jewelry, and you’ve basically nailed it. This costume works because everyone already knows the reference and the lines practically write themselves for group photos.

Fruit Basket

Each friend dresses as a different fruit using color-coordinated outfits and a simple felt or foam headpiece. Strawberry in red with green leaf details, banana in yellow, orange in, well, orange. It’s playful, cheap to put together, and genuinely funny in person.

Power Rangers

Bodysuits or matching colored outfits with a simple mask or helmet accent get the point across without much effort. This is a great pick if your group wants something a little more unexpected than the usual costume rotation.

Charlie’s Angels

Sleek pantsuits, or a mix of a blazer over a bodycon dress, sunglasses, and confident poses. This is an effortlessly cool option if your group prefers something a little more polished than costume-y, and it doubles as an outfit you could genuinely wear out afterward.

Candy Land Characters

Bright, sugary colors and playful accessories like oversized lollipop props or gumdrop headpieces. This idea leans into maximalist styling, which is trending hard right now, and it’s an easy one to make budget friendly with Amazon finds.

Grease Pink Ladies

Satin bomber jackets, cat-eye sunglasses, and high ponytails. This costume has that rebellious-but-cute energy that photographs beautifully, and the pink satin jackets are easy to find secondhand or on Amazon for cheap.

Zodiac Signs

Each friend represents their own sign with color and symbol details worked into the outfit, whether that’s a Gemini in a two-tone outfit or a Leo in gold and animal print. It’s a concept that naturally fits any friend group since everyone already has a sign.

Sailor Moon Scouts

Pleated mini skirts, matching colored bows, and knee-high boots. This anime-inspired look has been trending across social media for a couple of years now and still gets a strong reaction at parties.

Money Heist (La Casa de Papel)

Red jumpsuits and Dali masks make this one instantly recognizable and surprisingly comfortable to wear all night compared to some of the more elaborate options on this list. It’s also one of the more budget-friendly group costumes since jumpsuits are cheap and easy to find.

Disco Ball Squad

Sequined mini dresses in different metallic tones, platform heels, and glittery makeup. This is peak going-out energy and works especially well if your group already loves a night out anyway. Free People and ASOS both carry sequin pieces heavily in October.

The Bee Movie Cast

One friend as a bee in yellow and black stripes, others as flowers, and someone as Barry himself if you want to get literal about it. It’s an unexpected pick that always gets a laugh, especially paired with genuinely stylish outfits rather than a full costume-store getup.

Cheerleaders

Matching color schemes, pleated skirts, and a coordinated top with pom poms if you want to commit fully. This one is easy to shop for since athletic-inspired pieces are everywhere right now, from Amazon sets to Nordstrom’s activewear section.

Mario Kart Characters

Bright primary colors, simple accent pieces like a mustache sticker or a colored cap, and comfortable sneakers. This is a genuinely fun pick if your group wants something playful and nostalgic without a huge shopping trip.

The Bridgerton Ladies

Empire-waist dresses, pastel tones, and elegant hair accessories bring Regency-era glam to your Halloween lineup. This one leans more elevated than most costumes on this list, which makes it a great fit for a classier party.

Skeleton Crew, But Make It Fashion

Black bodycon dresses or jumpsuits with painted-on or printed skeleton details, paired with strappy heels or chunky boots. This is proof that a classic Halloween symbol can still look genuinely stylish instead of costume-y.

The Emojis

Bright yellow outfits with different facial expressions painted or printed on a simple graphic tee or sweatshirt. Low effort, high impact, and endlessly customizable depending on how many friends are joining in.

Playing Cards (Queens of Hearts, Diamonds, Clubs, Spades)

Coordinated black and red or full four-suit color schemes, with a card symbol worked into the outfit somewhere. This is a sleek, graphic option that looks intentional in photos without requiring elaborate sewing or props.

90s Cartoon Characters

Powerpuff Girls, Rugrats, or Hey Arnold, whatever your group grew up watching. Bright solid colors and one signature accessory per character usually does the trick. This taps into the nostalgia trend that keeps showing up across fashion and pop culture right now.

Vintage Pin-Up Girls

High-waisted shorts or skirts, tied-up blouses, and victory rolls or headscarves. This costume has real vintage glamour and works well for a group that wants something retro but still undeniably chic.

Mermaids

Iridescent or ombré dresses in shades of blue, teal, and purple, paired with shell or pearl accessories. Sequin and metallic fabrics are everywhere in stores this season, so this is an easier shop than it sounds.

Museum of Iconic Women (Frida, Rosie the Riveter, Cleopatra)

Each friend takes on a different influential woman throughout history, which gives everyone a chance to bring their own interpretation to the group theme. It’s a costume idea with a little more substance behind it while still being genuinely fun to wear.

Traffic Lights

Three friends in red, yellow, and green outfits, standing together for the obvious photo op. It sounds almost too simple, but that simplicity is exactly what makes it memorable at a party full of more complicated costumes.

Constellations

Black outfits with silver or white star accents, whether that’s face gems, a printed top, or fairy lights sewn into a jacket. This is a striking nighttime costume that photographs beautifully and works for groups of any size.

Whatever direction your group goes, the best group Halloween costumes are the ones everyone actually feels comfortable and confident in, not just the ones that look good on paper. Pick something that fits your friend group’s energy, split up the shopping list so nobody’s stuck doing it all, and give yourselves a trial run a few days before the party so nobody’s assembling a headpiece at 6pm on Halloween night.
