Matching family Halloween costumes do not have to be identical, which is a relief once the family spans a toddler and a six-foot adult. One theme carried across every age does the job, and the picks below run $25.95 to $55.95 a costume. Our kids' range and our adult range are built to two separate size charts, so on this one the theme was never the hard part. The sizing is.

Do matching family costumes have to be identical?
No. A family reads as matching when everyone is in on the same joke, not when everyone is wearing the same cut at four different sizes. The tradition is younger than it looks, too: in a 2025 Yahoo/YouGov survey of 1,770 US adults, 87% said they never did a family Halloween costume as kids, so most parents planning one this year are inventing it rather than repeating it. That is permission rather than pressure. There is no family-costume rulebook to break, and nobody at the door is checking your group against the one their own parents made them wear.
An alien pick-me-up for the adult
The Alien Costume Inflatable Pick Me Up ($55.95) is a one-size inflatable built for adults from 5'4" to 6'4". A built-in fan inflates it in seconds and keeps it full for up to 4 hours on 4 AA batteries, which covers most of a party before the batteries need a swap. The gag is a little green alien hauling you off with your legs dangling underneath, and the gag is the only thing this costume has to share with anyone else in the family.
The same joke, scaled down for the kids
The Alien PMU Inflatable Kids ($55.95) runs the same built-in-fan design sized for kids roughly 5 to 11 years old, inflating in about 60 seconds and holding for over 4 hours. Put it next to the adult version and you get one character pulling the same stunt at two different heights, which is the shot everybody ends up taking. Whether the two costumes came off the same pattern is nobody's first thought, and they did not.
How do you match a family that spans toddlers to adults?
Match a multi-age family by color, not by size chart. Put the kids in one color from the same line, then let the adults pick a color that pairs with it, since a toddler and a parent were never going to fit the same costume anyway. Our kids' and adult Morphsuit ranges are sized separately on purpose: kids' by height in Small, Medium, and Large, adults by their own chart. Every costume goes through over 30 measurement checks. Then do the boring part: measure each person once, keep the numbers somewhere you will find them again, and buy against that rather than the age printed on a label.
A solid color for the kids' half of the group
The Kids Blue Morphsuit ($25.95) covers Small, Medium, and Large by height, in 4-way stretch fabric with a hook-and-loop hood. Put the siblings in this one color, then have each parent pick a solid Morphsuit from the adult range in a color that answers blue rather than copying it. The family is obviously together in the photo, and nobody spent the evening in a costume cut for somebody else's body.
Is it safe to wear a bulky costume while walking kids after dark?
Give the inflatable the porch and the photos, and wear a stretch-fabric Morphsuit for the walk between houses. Both are great costumes; the Morphsuit is the one built for moving around in the dark, with nothing between you and the curb. A JAMA Pediatrics study of US pedestrian deaths found Halloween evening fatality risk 43% above a normal evening, ten times higher for children aged 4 to 8, peaking around 6pm. The other fix costs nothing: a second adult walking curb-side any time somebody in the group is in a costume that narrows what they can see.
What's the easiest way to plan a family look without buying one costume for everyone?
Pick the theme first, then cast it: one person per version of the same idea, rather than one costume bought four times. Asked to choose one route for a family with a wide age gap, we would take the shared color every time, because a color has no size chart and a character sometimes does. The shared joke, like the two alien pick-me-ups above, is the one to run when the whole family is in on the same bit. Our 3 person and 5 person Halloween costumes guides do this for same-generation groups, and our group and family Halloween costumes guide covers any headcount. Come back here when the group spans generations, because then it is sizing, not headcount, doing the work.
Frequently asked questions
How do you do matching Halloween costumes as a family?
Pick one theme and scale it across ages instead of buying one identical costume in every size. Two that work: the alien pick-me-up illusion in both an adult and a kids' size, or one color across the kids' Morphsuits with the adults in colors that pair with it. Either way the family matches without anyone squeezing into a design built for a different body.
Do matching family costumes have to be identical?
No. Coordinating by theme or color works just as well, and it sidesteps the fact that one design rarely fits comfortably all the way from a toddler to an adult. The same character at two scales, an adult and a child in the same alien pick-me-up costume, matches as clearly as two copies of one outfit.
How much do matching family Halloween costumes cost?
$25.95 to $55.95 a costume across the picks here. Two alien pick-me-ups, one adult and one kid, is $111.90 for the pair. The kids' solid Morphsuit is $25.95 a child, with each parent's adult solid Morphsuit on top of that.
How do you wash matching family costumes after Halloween?
None of these are machine-washable. On either alien pick-me-up, take the fan and battery pack out first and sponge-wipe the suit instead of submerging it, then let it dry all the way through before you deflate it for storage. The kids' Morphsuit takes a cold hand wash and dries flat rather than on a hanger. Do all of it the week after Halloween, not the week before the next one.
