Good 4 person Halloween costumes come down to one rule the whole group follows, not four people turning up in the same thing. Four is the headcount where you start needing that rule, because four people is four opinions. Friends and family rank third for costume inspiration nationally, per the National Retail Federation's 2025 survey of 8,045 consumers. Below are four routes, $20.95 to $50.45 a head, from an instant franchise team to a family of two adults and two kids.

Four ways to do a 4-person costume, compared
Pick the approach first and the costumes second. Doing it the other way round is how a group of four ends up with three Power Rangers and an argument. The table runs the four routes side by side. Settle sizing before color, because that is what actually splits a foursome: our Morphsuits run Medium to XX-Large, sized by height or by body measurement depending on the style, while the pinstripe gangster suit goes up to 3X-Large. This is real, searched-for ground too: people look up "4 person halloween costumes" on our own site, and until now nothing in our back catalogue answered it directly, just scraps spread across six unrelated pages, none holding more than a third of it.
| Approach | Effort level | Price each | Why it works for four |
|---|---|---|---|
| Franchise team of four | Low, zip and go | $40.95 to $45.95 | A recognizable squad with zero coordinating; everyone just picks a color |
| Any four colors you like | Low, zip and go | $29.95 to $43.35 | Same matched-group effect, not tied to one franchise |
| Everyone in the exact same look | Low to medium | from $50.45 | Sizes run Medium to 3X-Large, so four different builds fit the identical costume |
| Family of four, two adults, two kids | Low, zip and go | from $20.95 (kids), from $29.95 (adults) | One shared idea, sized separately for adults and kids |
What is the easiest way to get an instant team of four?
The easiest instant team of four is a Power Rangers Morphsuit in four different colors, because the costume does the recognizing for you and nobody has to explain the theme at the door. Red and blue are below; pink, green, white, black and yellow round out a seven-color range, so four people take one each and still leave three on the shelf.
Red Power Rangers Morphsuit
The Red Power Rangers Morphsuit ($40.95) is a full-body costume in 91% polyester, 9% elastane with 4-way stretch and a double zip, so getting in and out is quick even mid-party. It is sized by height across Medium to XX-Large, and the printed ranger design is built into the fabric rather than added as a separate mask.
Blue Power Rangers Morphsuit
The Blue Power Rangers Morphsuit ($45.95) adds an attached hooded mask to the same 4-way stretch fabric and double-ended zip, so it comes out of the pack more finished than the red and costs $5 more for it. Sized Medium to XX-Large by height, same as the rest of the range.
Every costume goes through over 30 measurement checks. Separately, our sizing runs by height rather than by a vague letter size, so the broad-shouldered one and the slight one in your group of four each read their own number off the same chart.
What if we want to match without a franchise costume?
Four solid-color Morphsuits do the same job as a franchise team without signing your group up to somebody else's property for the night. Pick any four from the range, no theme required beyond "we all showed up."
Red Morphsuit
The Red Morphsuit ($30.95) is our original full-body suit, 91% polyester and 9% elastane, with double zips and sizing that runs Medium to XX-Large by body measurement. If you are between two sizes, we would size up for easier movement rather than a tighter fit.
Silver Morphsuit
The Silver Morphsuit ($43.35) is the same fabric and fit in a metallic finish, so it reads as a distinct fourth color rather than a repeat of red. It runs the same Medium to XX-Large sizing as the red, and it sits at the top of the solid-color range: $13.40 more than the white.
White comes in at $29.95, and a fourth color off the same range closes the set. Nothing here needs a theme beyond the color itself, which is what makes it the route for four people who decided to dress up two days before Halloween.
What is the move when everyone is a different height or build?
The move for a group with different heights and builds is one costume with the widest size range, not four different ones you hope all fit. A Morphsuit sizes by height, but a tailored costume sizes by body measurement across a wider band, so it is the safer pick when your four are not all the same shape.
Pinstripe Gangster Costume
The Pinstripe Gangster Costume ($50.45) is a 1920s mob-boss look: pinstripe blazer, matching pants with an elastic waist, and a white shirt insert with an attached bowtie built in, so there is nothing extra to buy or lose on the night. It runs five sizes, Medium through 3X-Large, the widest range of any pick on this page, so four people of noticeably different builds can wear the exact same costume and all look like they meant to match.
Buy four in whatever sizes your group actually needs and the costume does the matching for you. This is also the honest answer if one of your four sits above an XX-Large: our Morphsuits stop there, the pinstripe suit carries on to 3X-Large, and we would rather point that person at the thing that fits than sell them a size that will not.
How do you do a group of four with two kids and two adults?
A family of four works best on one shared idea, sized separately for the adults and the kids rather than forced into one size chart. Two adults in a matching Morphsuit color plus two kids in the same color covers the group without anyone in an ill-fitting costume.
Kids Purple Morphsuit
The Kids Purple Morphsuit ($20.95) is sized by height in Small, Medium and Large, with a hook-and-loop hood attachment so the mask comes off fast if your child wants a break from it. Pair it with an adult Red or White Morphsuit for the grown-ups and the whole family reads as one costume in two different size charts.
That is two kids' sizes and two adult sizes in one color, and nothing else to buy. Wash all four the same way afterwards: cold hand wash, air dry, and no washing machine on any of them, kids' sizes included.
Do all four costumes actually need to match?
No. Four people agree faster on one rule than on one costume, and a color family or a shared theme carries a group photo as well as four identical suits do. Our group and family Halloween costume guide goes further into the techniques, including matching on a single shared prop rather than on the outfit underneath it.
If your headcount changes on the night, our 3 person Halloween costumes guide and 5 person Halloween costumes guide apply the identical approach a headcount either side, so a dropped-out friend or a surprise plus-one does not send you back to square one.

Frequently asked questions
What are good group Halloween costumes for 4 people?
A franchise team like four different Power Rangers Morphsuit colors, four solid Morphsuit colors of your choice, four of the same tailored costume in different sizes, or a family set of two adult and two kids' Morphsuits all work well for a group of four. Pick by how much coordinating your group wants to do: a franchise team needs the least agreement, a shared color needs a little, and matching exactly needs the most.
Do 4-person costumes have to match?
No. Four different Power Rangers Morphsuit colors, or four solid Morphsuit colors picked off the same range, both read as one group in a photo, and neither asks anyone to wear what somebody else is wearing. Matching exactly is one of the four routes on this page, not the default one.
How much do 4-person Halloween costumes cost?
Between $20.95 and $50.45 a head, depending on the route: solid Morphsuit colors start at $29.95, the Power Rangers Morphsuit range runs $40.95 to $45.95, the pinstripe gangster costume is $50.45, and kids' sizes start at $20.95. A family of four mixing two adult and two kids' Morphsuits is usually the lowest total cost of the four approaches.
Can two adults and two kids do a matching Halloween costume?
Yes. Pick one Morphsuit color and buy it in two adult sizes (Medium to XX-Large, by body measurement) and two kids' sizes (Small, Medium or Large, by height), rather than trying to fit a child into the smallest adult size. The kids' version adds a hook-and-loop hood attachment so the mask comes off quickly if your child wants a break from it.
