38 Baby Halloween Costumes That Are Frightfully Cute (and Actually Easy to Put On)

With their round little bellies, babies practically are pumpkins already! This baby pumpkin Halloween costume comes with an adorable hoodie and striped tights. The whole set looks comfy enough that your little one might actually wear it for more than five minutes. The zipper makes it incredibly easy to put on and take off, too. Parents say it’s warm and roomy enough to comfortably layer underneath — ideal if the weather gets cold where you live.

Keeping things low-key for your baby’s first Halloween? This Halloween pajama set offers two looks in one — perfect in case of an accidental blowout. The skeleton "costume" is a black bodysuit with a white bone pattern on the front. Snaps at the legs and neck make it easy to put on and take off. Bonus: Both this and the striped pumpkin-print suit can be reworn throughout the season as cozy pajamas. Parents say the fabric is soft and high quality and love that it comes in a preemie size.

I mean, it doesn’t get more appropriate than dressing your baby as Baby Yoda (or Din Grogu, if you’re caught up on The Mandalorian). Although there are many Baby Yoda costumes on the market, parents love that this option is easy to put on and take off a wriggly baby. It also comes with non-slip booties to keep their feet warm during the fall.

Make It a Family Costume: There’s an abundance of Star Wars Halloween costumes, making it easy to get the whole family involved. You and your partner can go all out with Mandalorian and Ahsoka costumes, or keep it low-key with these Mandalorian and Ahsoka sweatshirts.

There are an overwhelming number of Disney costumes for kids, especially when it comes to princesses. However, many of them come with accessories that aren’t suited for babies, which makes these dresses a popular choice. Made from super-soft cotton, this pullover-style baby bodysuit has a snap closure for easy dressing and diapering. Parents praise the costume for its quality and true-to-size design, noting that it could be worn beyond Halloween. They also appreciate the variety, with 21 designs inspired by Disney’s most popular leading ladies. 

Superheroes are a popular Halloween costume choice, but they often involve capes or masks — two big no-no’s for babies. These Avenger-themed bodysuits are a perfect alternative. Parents love the high-quality cotton-polyester blend and appreciate the three-snap closure for quick diaper changes. They do wish matching pants were included, but those are easy enough to buy separately. Each pack comes with three options — Captain America, Spider-Man and my personal favorite, The Hulk — so you’ll have backups in case of a blowout or just the urge for a mid-day costume change.

Pay tribute to Simone “GOAT” Biles (or Suni, Jordan and the rest of the Golden Girls) by dressing your baby in this American-flag leotard. I bought this for my budding gymnast and appreciate that it sparkles without the use of super-annoying glitter or rhinestones. The suit is super soft and stretchy, so your baby will be very comfortable. Pair it with Hanes’ navy blue sweatpants and a zip-up jacket, and you’ve got a gold-medal costume. You can also skip the leotard completely: dress your baby in the warm-up suit and a medal, and crowds will still cheer.

The Barbie buzz hasn’t died down since last year, and Etsy has the cutest costumes for your baby Barbie. My personal favorite is this neon set that pays tribute to the iconic rollerblading scene from the 2023 film. The leotard is fully lined, so you don’t have to worry about it irritating your baby’s skin. The pink shorts have plenty of stretch and can be worn long after Halloween. Though it's a splurge, you can also buy individual pieces to save money. And if you have a Baby Ken, there’s a version for him too.

My daughter wore this adorable A League of Their Own baby costume for her first Halloween, and it was perfect! The three-piece costume is true to size and made of a soft jersey knit that has some decent stretch. Sewn-on patches make it clear what team your baby is playing for, while printed-on buttons ensure there are no small parts for your little one to choke on. There’s also an option for parents of little Jimmy Dugans. 

There may be more “authentic” baby Harry Potter costumes out there, but those are often pricier and more difficult to put on a wriggly baby (not to mention the cap attachments could be a safety hazard). This cotton baby sleeper, however, offers a perfect nod to The Boy Who Lived, with its screen-printed scarf and Gryffindor crest. The ankle-to-chin side zipper makes dressing a breeze, while the five-snap closure allows for quick diaper changes. Plus, you get a bonus sleeper!

Make It a Family Costume: Transform your entire family into Hogwarts students with Gryffindor robes for boys, girls and adults. 

Who could resist a baby dressed as Elmo? This costume may be simple in design — a zip-up jumpsuit and hood — but it boasts several details that make it worth the money. Parents appreciate that the jumpsuit's feet are non-slip, giving new walkers a little more grip. Bonus: The long-sleeved, fluffy costume is guaranteed to keep your little one warm on a cold October night.

If Songs for Littles is the soundtrack of your life, then a Ms. Rachel costume is an obvious choice. While there aren’t any official Ms. Rachel Halloween costumes, it’s super easy to create. Just grab a pink t-shirt and a pair of denim overalls (like this set from Carter’s), and your baby is ready! You can also add the iconic pink headband, but some babies aren’t fans of hair accessories.

Blippi is another TV star who makes a perfect baby Halloween costume. All you need is this Blippi dress-up set, which includes his iconic accessories: a clip-on bow tie, adjustable suspenders, glasses and a blue-and-orange cap. Pair it with a blue button down and gray pants, and you have a complete costume. 

If my daughter could have spoken as a baby, she probably would have insisted on dressing as Bluey. This iconic Australian Heeler makes for a great costume choice, thanks to its simplicity and comfort. The super-soft jumpsuit — complete with a tail — features button closures for easy dressing and diaper changes. It also comes with a headpiece that has velcro straps, ensuring it won't irritate or hinder your child’s movement.

Make It a Family Costume: Bluey is nothing without her Mum and Dad, so get in on the fun with these adult Chilli and Bandit costumes. 

Looking for a spooky costume that's more sweet than scary? You'll love this adorable white bodysuit, which features a ghost face on the tummy and a matching hat with “Boo!” emblazoned on the brim. It's designed like a standard romper, with long sleeves to protect your baby’s sensitive skin and snaps along the inseam for easy diaper changes. Parents say it mostly fits true to size (though it may run slightly big on younger babies), and the fabric, while thin, is nice and soft. However, some parents noted that the fabric flares between the snaps, exposing some leg skin — so consider adding a layer underneath if you live in a colder area.

This cow costume is udderly adorable! Your baby will stay warm and cozy all night thanks to the soft, flannel material. The jumpsuit also includes a hood for extra warmth and to complete the cow look (though if your child doesn’t want to wear it, people will still get the idea). The double zipper extends to the back, making diaper changes super quick. Parents also note that the roomy fit makes it perfect for layering underneath, especially for those living in colder climates.

Perfect for wannabe cowgirls and cowboys, this set has everything you need for a classic costume. Made from ultra-soft cotton, the overalls feature a bold brown cow print that stands out from the denim-clad cowbabies you'll see on Halloween. The overalls also have fringe on the pants and button closures for easy diaper changes. The set includes a hat and a red bandana-style scarf, though I recommend skipping the bandana for safety. For extra warmth, I also suggest adding a shirt underneath.

Your baby will be ready to rescue Princess Peach and battle Bowser in this adorable bodysuit, designed to look just like a certain plumber’s iconic overalls and cap. Choose red for a Mario theme or green for a Luigi-inspired version. The short-sleeve bodysuit features snaps at the crotch, making diaper changes a breeze. Parents love the attention to detail and report using it not only for Halloween but also for themed birthday parties and birth announcements. Just be sure to layer up if it’s cold on Halloween. Some parents also mention that it runs a bit big.

Speaking of Princess Peach,  You won’t need a trip to the Mushroom Kingdom to find this cute Princess Peach baby costume. The short-sleeve dress looks just like the one Peach wears, thanks to tulle lace details at the waist and underskirt. It also comes with a diaper cover and a headband with a soft attached crown. Your little one will look every inch the princess! Just add tights and a long-sleeve bodysuit underneath if you live in colder climes.

Take your baby’s first Halloween to infinity and beyond with this iconic Buzz Lightyear costume. The set includes a polyester spacesuit with Velcro tabs on the back for easy dressing, along with gloves and a purple cap. The suit is roomy, allowing for layers on a chilly night. What parents really appreciate, though, are the soft, removable wings, which can be attached using the provided self-stick fabric tabs.

This adorable Mike Wazowski baby costume is sure to be one of the cutest on your Instagram feed.

Nothing stinky about this costume choice! Parents praise the black-and-white bodysuit for being soft and comfortable, with a zipper back that makes dressing easy. (It also has snap-button closures along the inseam for quick diaper changes.) Faux fur accents on the tail, headpiece and belly give the costume a plush look. The headpiece features pink-lined ears, adding to its authenticity, along with the paw-like boot covers. For a final touch, the tail attaches to the back with a hook-and-loop fastener, so you can easily remove it when your child needs to sit in a car seat or stroller.

For a cute take on the classic witch costume, look no further. This polyester baby witch dress comes with a matching hat and pants, so no need to buy extra items. One thing to note is that the shirt is attached to the dress, rather than a separate element so you can only put it on as one piece. Parents say it’s adorable and a good value, although many found the hat to be too small to stay on baby’s head.

For a low-key yet adorable costume, try this one inspired by the beloved children's book Where the Wild Things Are.

Your little one will look t-rexcellent in this dinosaur costume. The zip-up jumpsuit features “spikes” along the head and back for a more authentic look. Unlike other dinosaur costumes with separate headpieces, this version has an attached hood for added comfort. The hood has sewn-on eyes and a flap with sharp teeth for a terrifyingly cute appearance. Made of soft, cozy fleece, it provides plenty of warmth while remaining surprisingly lightweight, so your child won’t become a sweatosaurus.

The dinosaur suit is available in five colors: dark green, green, light green, pink and yellow. If your child isn’t in their Jurassic era, the jumpsuit also comes in several animal styles, including a koala, giraffe and tiger.

Show off the mini unicorn you’re raising in this colorful, cute ensemble. Parents love that this unicorn costume comes as a sweatshirt and pants set rather than a jumpsuit. Not only does that make diaper changes easier, but it also means you can repurpose the pants. Plus, the super-soft sweatshirt will keep your magical creature toasty and warm. The set also includes a wand, Velcro-attached wings and a unicorn headpiece. Some parents have mentioned that their little ones didn’t love the hood, but even without it, the costume remains truly magical.

There are buttons along the side if you prefer to put it on like a jacket. Just be sure to grab a pair of pants unless you want their legs to be cold.

You’ll want this adorable baby mermaid costume to be “part of your world” this Halloween.

Plus, each piece features ruffle details to make the mermaid look really pop. But the swimsuit isn’t the only noteworthy feature. The set also includes a slip-on skirt with fins at the bottom, and a zipper that allows the feet to be exposed for easy “walking” or covered to keep baby warm. A matching headband pulls the look together perfectly.

Pay tribute to the caffeine that kept you going during the newborn days with this simple yet superbly crafted coffee costume. Available in short-sleeve or long-sleeve styles, the bodysuit mimics the side of a Starbucks cup — complete with boxes to mark if your “short order” contains flavor shots, syrup, or milk. (There’s also a decaf option, but I’m sure you’re not checking that.) The costume includes an adjustable band that acts as the "cardboard" cup sleeve. For an additional fee, you can add a hat, pants, or both to complete the look.

You’ll be saying, “Thank you, thank you very much,” to this baby Elvis costume. Dress your little one as “The King” with this Halloween outfit, which includes a shiny onesie, pants, matching booties and a special hat. Parents also praise the fabric for being soft and high-quality. If you're unsure about sizing, it's best to order a size up.

No cowardly lions here! The adorable plush bodysuit has a zipper on the back and snaps on the legs for speedy diaper changes.

Since the romper is sleeveless, you’ll want to pair it with a long-sleeve bodysuit, as well as black leggings or tights, to keep baby warm.

This Ghostbusters baby costume is perfect for Halloween. A zipper down the front is not only on-theme, but helpful for getting it on and off. This sweet dress comes with a special headband and four name tags to complete the look.

Make baby’s Halloween out of this world with this adorable astronaut suit. This costume has snaps along the inseam that make for quick diaper changes and grippy socks to help them walk on the moon (or, you know, around the house). Some parents say the costume can be see-through, so you may want to pair with a regular onesie. Others recommend wearing real shoes instead of booties when going outdoors, since they’re fairly flimsy.

Future firefighter, coming through! This outfit — a traditional long-sleeve bodysuit with leg snaps — couldn’t be easier to get on and off. If you’re planning a longer outing, this no-frills outfit is a cute and comfy choice that your baby will happily wear for hours.
