Best Group Halloween Costumes: 7 Compared on Headcount and Sizes

The best group Halloween costumes give every person a character from the same story, so the group reads as one costume from across the room. A group of four or five friends is easiest to cast as the Scooby-Doo gang or the Ghostbusters, a young family gets the most from Bluey or Super Mario, and an office team of five or six fits the emotions of Inside Out.

Each theme below is built around one officially licensed core costume from Rubie’s or Disguise, and each entry lists how many people the theme covers, the matching characters sold to complete it and the sizes on offer. For solo, couples and pet ideas, see our guide to the best Halloween costumes.

1. Rubie’s Scooby-Doo Adult Costume: Best for a Group of Five

Scooby-Doo gives five people a part each: Scooby, Shaggy, Fred, Velma and Daphne. Rubie’s builds the anchor costume as a zip-front velour jumpsuit with a character hood showing Scooby’s face, an attached tail, a teal collar with an “SD” tag and paw covers on elastic straps. This listing is the men’s Standard size, which Rubie’s rates for up to a 44-inch jacket, and a men’s plus version is sold separately.

Rubie’s makes Shaggy, Fred and Velma, the human side of Mystery Inc., in matching adult cuts. Shaggy (shirt, pants, wig and a self-adhesive goatee) and Fred (shirt, pants, wig and scarf) come in the same men’s Standard size, and Velma (top, skirt, wig and glasses) is a women’s one size designed to fit up to size 12. For Daphne, Fun Costumes sells an officially licensed purple dress, scarf and headband set in plus sizes 1X to 5X, with an optional wig bundle.

What it does well

• Plush jumpsuit, hood, tail and paw covers in one zip-up piece.
• Shaggy, Fred and Velma come from the same maker in matching adult sizes.
• Velma’s one-size cut fits up to size 12.

What to know before buying

• Standard tops out at a 44-inch jacket; bigger builds need the plus listing.
• Rubie’s notes the Shaggy and Fred wigs may need styling and fluffing, and Velma’s socks are not included.

2. Rubie’s Ghostbusters Costume With Inflatable Proton Pack: Best for Adults and Kids Together

The Ghostbusters are a four-person team in one shared uniform, which makes this the simplest theme to cast across ages and builds. The Rubie’s version is a tan zip jumpsuit with Ghostbusters logo patches, a printed “No Ghosts” sleeve and customizable name tags, plus an inflatable proton pack that straps on. This listing is a men’s Standard, rated for up to a 44-inch jacket, and Rubie’s sells an adult plus-size version with the same inflatable backpack.

The four names for the tags are Venkman, Stantz, Spengler and Zeddemore. Rubie’s kids’ costume uses the same jumpsuit and inflatable pack in XS, Small (4 to 6), Medium and Large, so a parent and child can match exactly. A fifth and sixth person can go as Slimer or the Stay-Puft Marshmallow Man, both sold as adult costumes.

What it does well

• One uniform for everyone, so the group matches without coordinating outfits.
• Kids’ sizes XS to Large share the jumpsuit and inflatable pack design.
• Name tags let each person pick a Ghostbuster.

What to know before buying

• The proton pack is inflatable rather than a rigid prop.
• Standard fits up to a 44-inch jacket; larger adults need the plus listing.

3. Rubie’s Dorothy Costume: Best Wizard of Oz Group Costume for Mixed Ages

The Wizard of Oz fits four people as written, Dorothy, the Scarecrow, the Tin Man and the Cowardly Lion, and a fifth and sixth can join as the Wicked Witch of the West and Glinda the Good Witch. The Rubie’s Dorothy is the classic look: a blue gingham dress with an attached white blouse and puff sleeves, plus two matching hair bows. Toto in a basket is not included, but Rubie’s sells it as a separate accessory for kids or adults.

This listing covers Teen, One Size, Large and Plus, so a teenager, an adult or a plus-size Dorothy can all order from one page. Rubie’s also makes men’s Scarecrow, Tin Man and Cowardly Lion costumes, both witches, a Tin Man heart clock and a Cowardly Lion badge of courage for kids or adults, and a girls’ Dorothy in Small, Medium (8 to 10) and Large, so a child can take the lead role in a family group.

What it does well

• Teen, One Size, Large and Plus on one listing.
• Rubie’s sells all four main characters plus both witches.
• A girls’ Dorothy lets a child play the lead.

What to know before buying

• Toto in a basket is a separate purchase.
• The Scarecrow, Tin Man and Lion costumes are men’s cuts, so check the chart for anyone else in those roles.

4. Disguise Mario Costume: Best Super Mario Group Costume for Gamers

Disguise’s official Nintendo Mario costume is a one-piece blue jumpsuit with a foam hat bearing the M emblem and an adhesive mustache, and the listing suggests pairing it with Luigi, Peach or Bowser for a group look. That makes Super Mario the most flexible theme here: it works as a Mario and Luigi duo and grows to six with Peach, Bowser, Yoshi and Donkey Kong.

Disguise sells an official adult Luigi with hat and mustache, a Princess Peach dress and crown in women’s sizes such as Small (4 to 6), an official Yoshi hooded jumpsuit for adults and a deluxe Donkey Kong costume, and a men’s plus-size deluxe Bowser with an inflatable shell covers the villain. This Mario listing comes in Medium and X-Large, and Mario also leads our ranking of the best-selling video game franchises.

What it does well

• Scales from a two-person costume to a group of six.
• Official Nintendo license with the hat and mustache included.
• Disguise makes Luigi, Peach, Yoshi and Donkey Kong to match.

What to know before buying

• Only Medium and X-Large on this listing.
• The mustache attaches with adhesive rather than an elastic band.

5. Disguise Sadness Deluxe Costume: Best Inside Out Group Costume for Work

Inside Out turns a team into Riley’s emotions: Joy, Sadness, Anger, Fear and Disgust from the first film, plus Anxiety, who arrives in Inside Out 2. Disguise sells all six as costumes in adult sizes, and every emotion is a distinct character, which makes this the strongest pick for an office or classroom group where everyone wants their own look. Pixar’s sequel also introduced Ennui, Envy and Embarrassment, which gives a group of nine a character each.

The anchor is the Sadness Deluxe Adult costume: a printed turtleneck tunic, blue leggings, character glasses frames and a blue wig with an adjustable cap, in women’s Small (4 to 6) through XL (18 to 20). Disguise also sells Joy as an adult dress with a blue wig, Fear and Anger as men’s classic adult costumes, Disgust as a classic child/adult costume and Anxiety as a deluxe adult jumpsuit with a character headpiece. Makeup is not included, so anyone painting their face blue should patch-test it first.

What it does well

• Six licensed emotions from one maker.
• Sadness comes with the wig and glasses frames.
• Four women’s sizes, from 4 to 6 up to 18 to 20.

What to know before buying

• Blue face makeup is not included.
• Fear and Anger are men’s cuts while Sadness and Anxiety are women’s, so mixed groups need two size charts.

6. Disguise Bluey Bandit Costume: Best Family Halloween Costume With Toddlers

Bluey is the clearest family Halloween costume for a household of four: Bandit, Chilli, Bluey and Bingo. The listing for the Disguise Bandit costume says as much, suggesting it be paired with the brand’s Chilli, Bluey and Bingo costumes for a complete family costume. Bandit is an adult one-size hooded jumpsuit with his character art on the hood, his spots throughout and an attached tail.

Chilli is the matching adult hooded jumpsuit in Small (4 to 6), Medium (8 to 10) and Large (12 to 14). The kids are sized for little ones: the Bluey toddler costume, a jumpsuit with a detachable tail and a soft headpiece with felt ears, comes in 2T, 3T to 4T and 4 to 6x, and the Bingo costume comes in toddler sizes including 2T.

What it does well

• Disguise pitches Bandit, Chilli, Bluey and Bingo as one family costume.
• Toddler sizes start at 2T.
• Chilli comes in three women’s sizes.

What to know before buying

• Bandit is one size only, and Disguise advises checking the size chart.
• The Bluey toddler listing stops at 4 to 6x, so older kids need a different listing.

7. Rubie’s Michelangelo Costume: Best Ninja Turtles Costume for Four Friends

Four friends, four turtles. The Rubie’s Michelangelo costume, an officially licensed Nickelodeon item, comes with a jumpsuit with attached shoe covers, an orange eye mask, elbow and knee pads and a stuffable shell. Rubie’s sells Leonardo, Raphael and Donatello in the same adult men’s line, so all four turtles come from one maker.

A fifth and sixth person can play April O’Neil, sold as a women’s adult costume, or Shredder, whose men’s deluxe costume comes with a cape and mask. This Michelangelo listing comes in One Size and Extra-Large and is hand wash only. Because the mask covers only the eyes, the rest of each turtle’s face stays uncovered.

What it does well

• Four matching turtles from one maker.
• An eye mask instead of a full face mask.
• Pads and a stuffable shell are included.

What to know before buying

• Hand wash only.
• Weapons are not part of the set.

How to Size Group Halloween Costumes for Adults, Kids and Plus Sizes

Sizing is where group costumes go wrong, because a group often mixes brands, and each brand labels sizes differently. Rubie’s rates a men’s “Standard” for up to a 44-inch jacket, which matches the 44-inch chest of a men’s Large on the Rubie’s size charts, while Disguise labels women’s sizes by number ranges such as 4 to 6 and 18 to 20. Rubie’s also warns that costumes run smaller than regular clothing.

The Rubie’s charts give these chest measurements:

• Men’s: Small 37 in, Medium 41 in, Large 44 in, XL 47 in.
• Men’s plus: 2X 50.5 in, 3X 54 in, 4X 58 in.
• Women’s: XS (0/2) 33.5 in, Medium (8/10) 37.5 in, XL (16/18) 44 in, XXL (20) 46 in.
• Women’s plus: 0X (14W) 44 in up to 5X (32/34W) 64 in.
• Kids (unisex): XXS/XS for ages 3 to 6, S/M for 7 to 10 and L/XL for 11 to 16, with L/XL covering 62 to 67 inches tall and 100 to 120 pounds.

To cut down on returns, work through the group in this order:

1. Measure each person’s chest and waist over the clothes they will wear underneath.
2. Match every costume to its own brand’s chart, not to their usual clothing size.
3. Size up when someone falls between sizes; Rubie’s says form-fitting costumes tend to run small.
4. Check that every character exists in the sizes your group needs before buying the first costume, since not every item comes in every size.

Costume Safety for Groups: Flame-Resistant Labels, Masks and Visibility

Federal rules already apply to these costumes: the federal flammability standard for clothing textiles covers fabric “ready for use in an article of wearing apparel, including garments and costumes finished for consumer use.” Fabric that burns rapidly and intensely, a flame spread in under 3.5 seconds for a plain surface fabric, falls into Class 3 and may not be used for clothing.

The Consumer Product Safety Commission’s Halloween guidance adds these checks for every costume in the group:

• Flame Resistant label: look for it on costumes, masks, beards and wigs. It does not mean an item cannot catch fire, but that it resists burning and should go out quickly once away from the flame.
• Cut: avoid flimsy materials, big baggy sleeves and billowing skirts, and keep hems short enough not to trip over.
• Visibility: choose light, bright costumes or add reflective tape, and give trick-or-treaters flashlights.
• Masks: face makeup is the safer choice; if someone wears a mask, it should fit securely with eyeholes large enough for full vision.
• Accessories: swords, knives and similar props should be soft and flexible, which matters for a group of turtles.
• Hats and shoes: tie hats and scarves on securely and wear well-fitting, sturdy shoes.

For face paint, such as the blue skin on Sadness, the FDA recommends testing the makeup on the wearer’s arm 24 to 48 hours ahead and checking that its colors are on the FDA list of approved color additives. The FDA also warns that decorative contact lenses sold without a prescription are illegal. And if you carve a pumpkin for the porch, keep it away from landings and doorsteps where costumes could brush a candle flame, or light it with a battery-powered candle instead.

Which Group Costume to Buy

For four or five adult friends, the Rubie’s Scooby-Doo or Ghostbusters costumes are the safest bets: the gang and the team each have a clear cast, and Rubie’s sells the matching pieces in the same adult sizes. Ghostbusters also has kids’ sizes from XS, so it is the better of the two when children are joining. A group of exactly four can split the Ninja Turtles, with April O’Neil or Shredder for anyone extra.

Families with toddlers should start with Bluey, the only theme here whose maker pitches its four costumes as one family costume, with toddler sizes from 2T, while families with older kids have more room with Super Mario or The Wizard of Oz, which runs from girls’ sizes to adult Plus. For a work group of five or more, Inside Out gives everyone their own character from Pixar’s two films.

Frequently Asked Questions

What are good group costumes for 4 people?

The Ghostbusters (Venkman, Stantz, Spengler and Zeddemore), the four Ninja Turtles, the Bluey family (Bandit, Chilli, Bluey and Bingo) and The Wizard of Oz (Dorothy, the Scarecrow, the Tin Man and the Cowardly Lion) each have exactly four main characters.

What is the best family Halloween costume with a toddler?

Bluey is the easiest: Disguise sells Bandit and Chilli for adults and Bluey and Bingo in toddler sizes such as 2T. The Bandit listing itself suggests pairing the four as a complete family costume.

How do you choose sizes for a group costume?

Measure each person’s chest and waist, then compare them with the size chart of the brand that makes their costume, since Rubie’s and Disguise label sizes differently. Rubie’s advises sizing up when in doubt because form-fitting costumes tend to run small.

Are Halloween costumes flame resistant?

Costume fabric must meet the federal flammability standard for clothing textiles, which bars dangerously flammable Class 3 fabrics. The CPSC still advises looking for a “Flame Resistant” label, which means the item resists burning and should go out quickly away from a flame, not that it cannot catch fire.
