The National Retail Federation's 2026 Halloween survey of 7,889 consumers, conducted September 1 to 9, found that 74% of consumers plan to celebrate, and it lists dressing in costume (50%) among the top ways consumers mark the occasion. We sorted the themes by what each person wears, not by this year's loudest movie.
Know your headcount already? Our guides for 2 people, 3 people, 4 people, 5 people, and 6 people pick sets of that size. Pairs start from our couples costume guide, and our group and family costumes page holds the whole range.

What can you order for each theme?
Pack contents and size ranges below come from each product page.
1. Color squad: one solid color per person
Each person takes one solid color, and the group reads as a set at any headcount. The Kids Pink Morphsuit is a full-body spandex suit, 91% polyester and 9% elastane, with four-way stretch and a hook-and-loop hood. Small fits most children aged 4 to 6, Medium 7 to 9, and Large 10 to 12. The pack is the suit and nothing else.
Between April 22 and October 11, 2026, 23 of the 91 orders recorded on our US website that held three or more items (about one in four) included a Morphsuit of any kind, solid or printed, against 502 of 5,459 orders overall (about one in eleven). Adults pick from the solid color Morphsuits, kids from the kids solid color Morphsuits.
2. Plumber duo: one retro look, two builds
The Men's Purple Plumber Brother Costume is a purple jumpsuit with an attached shirt, gloves, a faux mustache, and a hat carrying an initial. It comes in men's Large and X-Large only, in a relaxed fit that layers over a base layer or light clothing.
The partner can go inflatable. The Mens Inflatable Red Plumber Hero Costume is one size fits most adults. Its fan is built in and runs off a battery pack, and you supply the 4 AA batteries.
3. Ninja clan: kids and adults in one theme
The Boys Gold and Black Ninja Costume with Backpack includes a hooded jumpsuit with an integrated mask, matching gloves, a backpack, two toy swords, two toy daggers, and two foam throwing stars, in four sizes from Toddler through Large. The Boys Silver Dragon Ninja Costume is an all-in-one jumpsuit with an attached hood, a detachable face cover, a weapon backpack holder, toy swords, daggers, and throwing stars, and gloves, in Toddler through Large (3 to 12 years).
For adults, the Women's Black Silver Dragon Ninja Playsuit Costume includes an overskirt dragon panel, leg straps, a hood, a choker, and a separate mask in Small through 3XL. The Women's Black and Red Ninja Costume runs Small through X-Large. The rest are on our ninja costumes and kids ninja costumes pages.
4. Power Rangers team: one color per kid
In a Power Rangers team, the color decides the character. The Boys Mighty Morphin Blue Power Rangers Morphsuit is a full bodysuit in 91% polyester and 9% elastane, with a zip-up back and a hook-and-loop hood. The Boys Mighty Morphin Red Power Rangers Morphsuit and the Kids Black Mighty Morphin Power Rangers Morphsuit complete a trio. All three come in Small through Large, and the Blue and Black pages say to allow extra room or size up if your child is between sizes.
Our kids Power Rangers costumes and Power Rangers costumes pages list the rest of the team.
5. Inflatable herd: every person a different shape
The Astro Jetpack Inflatable Kids costume is one size designed to fit most children and includes an inflatable suit with an attached rocket pack, a fan unit, and a battery pack. The Eggplant Inflatable Costume is one size fits most adults. You buy its 4 AA batteries separately to power the fan, which is built in.
Both product pages say hand wash only, with the batteries or battery pack taken out first. Browse the adult inflatable costumes and kids inflatable costumes for the full set.
6. Onesie squad: one comfort-first family
A onesie squad suits a family that spans ages: nothing to power, nothing to assemble. The Girls Black Cat Onesie Costume is a plush all-in-one jumpsuit with an attached tail and a glittery ear headband in sizes for ages 4 to 14, and the page says to remove the headband before washing. The Boys Dalmatian Puppy Onesie Costume has a spotted bodysuit, a floppy-eared hood, a detachable tail, and paw foot covers. It comes in just three sizes, for babies and young children.
Adults join in the Adult Turkey Onesie Costume: a jumpsuit, a hood, wings, and boot covers, sized by height from 155 cm to 200 cm (about 5 ft 1 in to 6 ft 7 in).
7. Pick-a-category crew: nine or more people
From nine people up, name a category instead of a character and let each person choose a costume inside it. Nobody needs the same pack, so sizes and budgets stay personal. Start from decade costumes, pirate costumes, movies and TV costumes, or sports costumes, and keep one shared color or prop to tie the group together. Our group costume guide sorts picks by budget, and our scary group costumes guide covers the horror side.
How does a crew plan and order group costumes?
Between April 22 and October 11, 2026, fewer than 2% of orders recorded on our US website (91 of 5,459) held three or more items. We suggest a theme where every person can order their own piece.
- Count heads. A firm headcount tells you which row of the table applies.
- Fix the theme before anyone shops. Post the theme and the color or character each person has taken in the group chat, so nobody doubles up.
- Size from each product's guide. Our costumes are measured across 30+ points, and each page carries its own size guide. Where a page says to size up when you are between sizes, do.
- Order as soon as sizes are settled. Check the delivery estimate at checkout for each order.
- Hand wash afterward. Give fabric costumes a cold hand wash and an air dry, and read each product page's care block before the first wash; the inflatables ask you to take the batteries out first.
Frequently asked questions
What are the most popular group costumes for 2026?
We would put seven themes in front of a crew for 2026: a color squad, a plumber duo, a ninja clan, a Power Rangers team, an inflatable herd, a onesie squad, and a pick-a-category crew. Each scales to a headcount, and every person orders their own piece.
What are the best group costume themes for a large group?
For nine or more people, we suggest a color squad or a pick-a-category crew, because each person wears one solid color or chooses a costume inside one shared category. We would cap an inflatable herd at about ten people.
What are funny group costumes for 2026?
An inflatable herd turns every person into a different oversized shape, such as the Eggplant Inflatable Costume for adults and the Astro Jetpack Inflatable Kids costume for children. For a funny look with nothing to power, try the Men's Purple Plumber Brother Costume on its own.
How do you pick a group costume theme everyone will wear?
Count heads, then choose a theme where each person can pick their own color, character, or costume inside one category. Add one shared element, such as a color or a prop, so the group still reads as a set.
Can kids and adults wear the same group costume theme?
Yes. A ninja clan has kids' packs from Toddler through Large and women's ninja costumes from Small through 3XL, and a onesie squad runs from a baby in a puppy suit to an adult turkey sized by height.
