Best Kids Costumes of 2026

The stand-up collar is what makes this look like a costume rather than a black dress with a bat print, and it's also the piece most likely to let the outfit down: the collar on this one has a habit of flopping forward instead of standing. Even so, we think it's the best-made garment in this group. The fabric has real body, the bodice is detailed rather than printed, and it isn't see-through — rarer than it should be in kids' costumes.

Sizing takes a little thought. The small is cut for roughly a six-to-eight, with enough room that a tall nine-year-old can wear leggings and a long-sleeve tee underneath without the dress pulling across the shoulders. If your child is at the top of the size or tall for their age, go up; the fabric has some stretch and the length is more forgiving than the shoulders.

The cameo choker does most of the character work, which matters if your kid tolerates a costume but not face paint. The flared sleeves and the lace-up detail on the bodice are the parts that read from across a school gym, and the whole thing looks like something a villain would actually wear. It's a costume for a kid who wants to look properly sinister in the parade rather than adorable in a photo.

Mario is where we start when a kid hasn't settled on anything, because the character reads instantly — hat, mustache, jumpsuit — and this is the officially licensed Nintendo costume rather than a lookalike. The mustache is also the first practical problem: it arrives as a separate piece with no adhesive, so it either gets trimmed and stuck on by you or, more likely, spends the night in the bag while your kid runs off as Mario anyway. We don't hold that against it. The rest of the outfit does the work.

Fit is where this holds its place as our default. It runs true to size through most of the range, and the cut leaves room for a T-shirt and leggings underneath — which is what you want on a night that starts cold and ends in a warm gym. Sleeves run a little long, easy to roll. What counts for us is that it goes on without a fight and stays on through a party, and this one does.

The fabric is thin, and for a school parade or a warm party that's the right call: it's the reason a kid doesn't overheat and start stripping in the middle of a classroom. What keeps this one in rotation is everything after Halloween. It gets worn to the store in November, and it comes through repeated washes still looking like Mario.

What it isn't is a premium costume. Up close it's a printed jumpsuit, and it won't be handed down to a cousin. What it is: the costume a preschooler puts on in the morning and forgets they're wearing, which is the thing we care about most in this category.

What's in the box makes the case for this one: a full costume plus a headpiece, a belt and a set of prop accessories, so a kid who has been promised a ninja gets a ninja with something to hold. The headpiece and belt are what pull it together — without them you have a blue outfit, with them you have a character.

Fit lands about where it should through the middle of the range, with enough slack for a long-sleeve tee and leggings when the forecast turns. The legs tie at the ankle, which looks right and is mildly annoying for a kid still working out bathroom trips, so factor that in. Where this one surprised us is durability: it goes through the wash and comes back out, and these get handed down rather than worn out.

Sizing runs a touch small, and the accessories are one size across the whole range, so a bigger kid can end up with a headpiece that doesn't quite sit. Set against that, it's the most complete costume in this group for the money, and the one we hand to a kid who wants to disappear into character for a whole day rather than pose for a photo.

The helmet is what makes this a football uniform instead of a jersey and a pair of pants, and it's better than a costume helmet has any right to be: molded, padded inside so it doesn't grind against a forehead, and light enough that a kid keeps it on for the length of a party. The jersey and pants underneath are costume-grade — thin and printed, and fine for what they are.

Sizing is the weak point, and it's the one thing to plan around. The size bands run small for plenty of kids, and the helmet is the piece that decides whether the whole thing works, because a helmet that swallows a head is worse than a jersey that's a little loose. Measure height and head, order against the chart rather than the age, and go up if your child lands between. Do that, and this is the most convincing sports costume in the group.

The jersey is thin under pads and a helmet, and less fine on a cold night without something underneath. What sells it anyway is how far past Halloween it goes: this becomes the uniform for every Sunday of the season, and it holds up being worn that way. You pay for the helmet and for a costume that gets a dozen wears before December, which is a different calculation from a one-night outfit.

The dragon gets the biggest reaction from other kids of anything in this group, and it earns it: wings, a tail, a scaled print and a mask that reads as a dragon rather than a lizard. The fabric is soft and doesn't itch, and the details are good enough that it doesn't look like a supermarket costume in photos.

The wings and tail attach with Velcro, and that's the weak link. The wings are heavy enough to pull the Velcro loose on a running kid, and the tail can drag the back of the suit out of shape. It's manageable — check both before you leave the house and expect to press them back on once or twice — but out of the box, plan on reattaching something before the night is done.

The mask has its own problem: the strap is the first thing to go, and once it snaps the mask becomes a prop rather than something wearable. Fit is true through the middle and runs small at the top, and the tail is heavy enough that a smaller kid feels it pulling with every step. This is a costume for a kid who will wear the whole creature, not just the wings.

None of this is hidden from a kid. They see the wings and the tail on the front of the package and that's what they want, and a plain printed dragon suit will disappoint them. We choose this one for exactly that reason, and we accept the maintenance that comes with it: for a four-to-seven-year-old set on being a dragon, the fuss is worth it.

Violet is a specific kid's specific choice. If your child wants to be the invisible one from The Incredibles, this is the licensed version of that suit, with the belt attached and a fabric eye mask in the box, and it reads instantly to anyone who has seen the film — which is the entire reason to pay for a licensed costume rather than improvising one from clothes you already own.

Sizing runs big, and that's useful rather than a fault: a seven- or eight-year-old fits the 4-6x with room, and on a five-year-old it's loose rather than baggy. The pull-on cut has no closures to fight with, and there's space for leggings and a long-sleeve tee underneath, which is how you'll want it on a late-October night.

The fabric is thin — noticeably thinner than the vampire or the Mario suit — and thin plus a kid who plays hard is how seams start to go. The neckline is where these give first. Machine washing is allowed, which is more than some costumes here offer, and a cold wash and a low dryer gets the most out of it.

Licensed, roomy enough to layer and machine washable, it's the sensible choice for a family doing a group costume, and the least fussy licensed option here for a younger kid. It won't survive three years of dress-up the way the ninja does, but it gets you through Halloween and a decent stretch of November.

Glow-in-the-dark is the entire pitch here, and it works — with a catch. The suit and gloves soak up light and glow for a while; the mask doesn't glow at all, and a costume that has been sitting in a closet all day won't light up on its own. A stretch under a bright lamp before you leave the house is the difference between a glowing skeleton and a grey one.

Sizing is generous, which is why this works on a range of kids: roomy through the middle, big enough for a husky kid without a fight, and wide enough to wear pajamas underneath — worth planning for, since the fabric is thin. The mask has wide eye openings, which sounds minor until you've watched a child navigate a dark sidewalk in something they can barely see out of.

There's nothing premium here. It's a printed suit with a mask and gloves, and it will pill and fade long before it becomes an heirloom. But glow-in-the-dark does something none of the other costumes in this group do on a dark street, and it does it with the least fuss. For a kid who wants to be scary rather than a specific character, this is the one we hand over.
