Our Picks at a Glance
How To Choose The Best Baby Bat Costume
A bat costume for a baby is really just an adorable piece of clothing with ears and wings attached. The trick is finding one that acts like good clothing: soft against sensitive skin, easy to get on and off, and warm enough for a cold evening. You will be dressing a wiggly, possibly uncooperative human, so every detail matters.
Fabric and warmth level
Before you fall for the photos, check the fabric. Fleece and flannel options give real warmth for outdoor nights, while lighter cotton blends suit indoor parties or warmer climates. Many parents say a mid-weight fabric is the balance — thick enough to keep a baby warm, but not so heavy that they overheat in a warm house.
Sizing and room to grow
Babies grow fast, and most of these costumes run either baggy or a bit small depending on the brand. Look for a style with some extra room, since a loose fit means you can layer a onesie underneath for warmth. Read the size chart carefully and check whether buyers report the sizing runs true, big, or small before you order.
Closure and diaper access
The fastest way to ruin a fun evening is a costume that takes ten minutes to get off for a diaper change. Zippers and snaps win here, especially double zippers that open from the bottom. Velcro is quick but can stick unexpectedly or wear out, and some parents find it harder to manage on a squirmy baby.

In-Depth Reviews
1. ABTSHU Baby Animal Costumes Toddler Halloween Dress Up Outfit
Our pick — over 4.5★ from 950+ verified ratings; the strongest balance of quality and price.
A warm, baggy flannel onesie that survives diaper changes and cold nights without a fight.
Most parents shopping for a baby costume worry about two things: will it keep my baby warm, and will they actually wear it? This flannel and fleece outfit answers both. The flannel-and-fleece fabric is soft on both sides, and the baggy cut leaves room for a layer underneath on cold nights. It’s machine washable, so a post-candy cleanup is no problem.
The double zipper opens from the bottom for quick diaper changes. It opens from the bottom, which makes middle-of-the-night diaper changes fast and easy, and owners mention it holds up well to repeated washing. Sizing runs the full gamut from 1-3 months up to 4-5 years, and the fit is accurate enough that an 18-24 month size worked for a 14-month-old with a bit of room to spare.
The trade-off is warmth: cozy for cold nights, but a few buyers in warmer climates found it too toasty. That is a compliment in most places, though. “Definitely a little big on my 8 month old but stayed on fine, he didn’t fight it at all, and it was sooo adorable,” customers note.
What wins parents over
- Quality is the most-praised trait, with owners consistently impressed by the stitching and fabric
- Double zipper makes diaper changes genuinely easy
- Fleece-lined warmth that works for cold outdoor nights
- Baggy cut lets you layer underneath without a squeeze
The trade-offs
- Runs a touch big, so size down if you want a snug fit
- Too warm for mild-climate areas
- Zipper can be tricky for little fingers to manage
Reach for this if: you want a warm, durable, machine-washable costume that will last through multiple wears and washes.
Look elsewhere if: you live somewhere warm or need a lightweight option for an indoor party.
2. FANCYINN Infant Baby Black Bat Orange Cloak Romper with Big Ear Hat
A cotton onesie-and-hat duo that keeps babies cool, comfy, and camera-ready.
If your Halloween plan is mostly indoor photos and a short walk around the block, this cotton romper is a smart pick. The cotton is breathable and cool, with one parent planning to reuse it as a nightgown. It comes as a two-piece set: a long-sleeve romper with snaps and a separate bat hat with big ears.
At 5.64 ounces, it’s one of the lighter options here, which is exactly what you want for a baby who runs warm or for a party in a heated house. The cotton is thicker than a basic tee but still breathable, and the snaps are easy to manage for quick changes. It’s a simple, classic look that photographs beautifully.
The catch is the hat: ears flop and it runs big. The ears tend to flop down, and the hat itself runs big — a common refrain across reviews. It still does the job, but if you want crisp, upright bat ears in every photo, you may need to adjust or roll the hat. “Super easy onesie and classic costume. Hat was a tad too big but did the job,” reviewers point out.
Cool and comfy: breathable cotton is ideal for indoor events, and the snaps make changes simple.
Floppy factor: the ears do not stand up reliably and the hat runs large, so size down and plan to fiddle.
Best for: parents who want a lightweight cotton costume for indoor parties or warm climates.
Think twice if: you need a warm outdoor costume or crisp upright ears for photos.
3. Weixinbuy Toddler Baby Halloween Costume Bat Style Hooded Coat
A fleece sweatsuit that moonlights as real winter outerwear long after Halloween passes.
This bat costume is a hooded coat and pants set made from soft, warm fleece — essentially a wearable sweatsuit with bat ears and wings sewn on. Parents love that it functions as actual cold-weather clothing, not just a one-night costume. Buyers describe it as “basically just like a soft sweat suit,” and many say their kids wore the jacket on its own all winter.
The zipper front makes it as easy to put on as any regular jacket, and it’s warm enough for outdoor trick-or-treating without a coat underneath. The design is a hit with toddlers who want to move — the soft fleece doesn’t restrict crawling or walking. It’s available from 9 months up to 6 years, and the sizing generally runs true with a little room to grow.
The zipper can stick, with one parent unable to unzip it after getting it on. It’s a minor annoyance rather than a dealbreaker, but worth knowing before you buy. The design is so popular that the wings were a hit, even if the interior can feel a bit rough against bare skin for some.
Why it earns its keep
- Warm fleece works as real winter wear beyond Halloween
- Zipper front is easy on and off, like a regular jacket
- Pants are wearable with other shirts after the holiday
- Available in a huge range from 9 months to 6 years
Watch out for
- Zipper can stick and sometimes gets stuck on the way off
- Some find the interior fabric a bit scratchy
- Fits a touch small for some toddlers
Grab it if: you want a costume that doubles as a winter coat and gets worn for months, not one night.
skip it if: you need a lightweight option or your toddler hates zippers.
4. Waghaw Baby Bat Costume My 1st Halloween Outfit Pumpkin Newborn Bodysuit
A soft, stretchy bodysuit designed specifically for a newborn’s very first Halloween.
This one is built for the tiniest trick-or-treaters. The material feels like a soft pajama t-shirt — stretchy, comfortable, and not scratchy at all — which is exactly what you want against a newborn’s sensitive skin. Parents report babies stay comfortable and fuss-free in it, which is the highest compliment a baby costume can earn.
The long-sleeve bodysuit pulls over easily and has a matching hat with bat ears. It fits most newborns well, though a few note it runs a tad big. It’s warm enough for a quick outing, but most parents agree you’ll want blankets or a layer for a truly cold night — the fabric is soft and cozy, not thick.
“This baby bat costume is really cute and well-made. The material is soft and warm, not too thick, fits my newborn nicely, and was easy to put on,” shoppers say. The recurring gripe is the ears: they are floppy and don’t stay up on their own. It’s still cute, but if upright ears matter to you, keep looking.
Newborn-ready comfort: soft, stretchy fabric that babies don’t fight, plus easy pull-on styling.
Floppy ears: the hat’s ears don’t stay upright, and the fit runs a touch big for some newborns.
Choose this for: a newborn’s first Halloween photo session or a quick, comfy costume moment.
Pass if: you want the hat ears to stand up crisply or need serious cold-weather warmth.
5. AGQT Baby Bat Costume Boy Girls Halloween Outfit with Hat
A thicker-than-expected cotton set that was made for picture-perfect moments.
This costume was practically designed for the camera. Parents report it was “great for a photoshoot with my 3 month old,” and the thicker cotton material means it photographs well without looking cheap. It works for sizes 0-24 months, and the soft, stretchy cotton is comfortable enough that babies don’t get fussy wearing it.
The material is thicker than most buyers expected, which is a pleasant surprise for chilly Halloween evenings. It pairs easily with black leggings or tights for a complete look, and the fit is generally true to size with a bit of room. The hat is included, but be prepared for the same floppy-ear issue that shows up across most bat costumes.
The ears don’t stay up on their own, and the fit runs bigger than the size chart suggests. For a photo session where you can position the hat just right, these are non-issues. For an all-night wear, you might find yourself adjusting.
Photoshoot ready: thick, soft cotton that looks great in pictures and keeps babies comfy.
Ear disappointment: the hat’s ears flop down on their own, so plan to position them manually.
Buy it for: a Halloween photoshoot or a short, picture-heavy outing where you can adjust the hat.
pass on it if: you need ears that stay up all night or a snug, true-to-size fit.
6. Infant Vampire Bat Costume Soft Minky Fleece Hooded Wings
A plush, huggable Minky fleece costume with shimmering wings and embroidered facial details.
If you want the most luxurious-feeling bat costume on this list, this is it. Made from 100% soft polyester in a Minky fabric, it feels like a stuffed animal you can dress your baby in. The pink plush belly, inner ears, and scale fabric on the wings create a visual effect that stands out in photos and gets compliments all night.
The hood comes with embroidered facial features, soft-sculpted ears, and teeth — details that make it look far more premium than a basic onesie. The hook and loop fastener on the side front makes dressing easy, and the fabric is warm and thick, ideal for cooler climates. One parent called it “not as thick as I thought it would be,” which was a pleasant surprise for worried-about-overheating families.
The trade-offs are real, though. The hood runs big, the arm sleeves run short, and the fit is snug with no stretch. A few buyers found loose threads around the Velcro, and one reported a seam hole after an hour of wear. It’s adorable and warm, but quality is somewhat inconsistent for the price point.
The plush payoff
- Minky fleece is incredibly soft and huggable
- Detailed hood with embroidered face, ears, and teeth
- Thick and warm for genuinely cold nights
- Shimmering wings add a premium touch
Reality checks
- Hood runs big and arm sleeves run short
- Snug fit with no stretch — size up if between sizes
- Some quality concerns like loose threads and seam wear
- Velcro closure is a bit awkward for quick changes
Worth it for: parents who prioritize softness and photo-worthy details over durability.
Not for: families who need a reliable all-night costume or easy diaper access.
7. California Costumes Bite Sized Bat
A jumpsuit-and-hood set with detachable wings built for toddlers who love to flap.
This one understands what toddlers actually do in a costume: flap their wings. The Bite Sized Bat features a separate jumpsuit and hood, with wings that detach for comfort when the flapping gets old. Parents report kids love the wing action — one grandmother said her granddaughter “loved flapping the wings” all evening.
The headpiece has big, wonderful ears with an under-the-chin Velcro strap that keeps it in place, which is a thoughtful detail most bat hats lack. It’s easy to put on with Velcro in the back, fits well over warm clothes underneath, and kept one toddler warm on a cold Halloween night. The comfort level is high enough that kids don’t fight it.
The wings limit arm movement, and the back Velcro closure drew one parent’s “horrible” review. The wings are the star of the show, but they restrict mobility, so expect some toddler frustration if they want to reach for things. It’s adorable enough that most families accept the quirk.
Why toddlers love it
- Detachable wings kids can flap and play with
- Under-chin Velcro strap keeps the hat in place
- Comfortable, roomy fit over warm layers
- Gets constant compliments and attention
Keep in mind
- Wings limit arm movement significantly
- Back Velcro closure is not great quality
- Hat runs a bit big for some toddlers
Reach for this if: you have a toddler who wants to be an active bat and loves playing with wings.
Look elsewhere if: you need free arm movement or a sturdier closure than Velcro.
8. Infant Girl Bat Halloween Costume Baby Pink Vampire Bat Hooded Bodysuit
A pink hooded bodysuit with wings that fits true to size and keeps babies warm.
This all-in-one costume nails the pink bat aesthetic without sacrificing function. The long-sleeved bodysuit comes with attached wings and a hood, designed for infants aged 0-3 months. It’s made from durable polyester that stands up to baby play while keeping its shape and color through machine washing and low tumble drying.
The fit is the standout feature here — parents consistently report it runs true to size, which is rare in the costume world. It fit a 3-month-old perfectly and a 10-month-old comfortably on the roomier side. The material is thick enough to keep a baby warm on a cold Halloween, and the hood covers ears well. Just note it doesn’t come with tights or pants, so you’ll need black bottoms to complete the look.
The wings look adorable when baby raises their arms, and the all-in-one design makes diaper access easy — a feature parents genuinely appreciate. The one caution is sizing: the 0-3 month size fits average 2-3 month babies but runs too big for true newborns. And the wings can make carrier use a bit awkward if you’re babywearing.
What stands out
- True-to-size fit that parents can rely on
- Thick, warm material for cold Halloween nights
- Machine washable and durable for repeated wear
- Adorable pink wings that photograph beautifully
Consider this
- Runs too big for true newborns despite the 0-3 month label
- Does not include pants or tights — buy black bottoms
- Wings can make carrier use awkward
Pick this if: you want a reliable, true-to-size pink bat costume that’s warm and durable for a 2-10 month old.
it’s not for you if: you have a brand-new newborn or need a complete outfit with pants included.
Understanding the Specs
Fabric and warmth
The fabric is the single biggest factor in whether your baby stays happy. Fleece and flannel hold warmth well for outdoor nights but can overheat a baby indoors. Cotton is breathable and cool, making it ideal for warm climates or indoor parties. A thicker cotton or mid-weight fleece is the balance for most families — warm enough for a quick outing without being suffocating.
Closure type
How the costume opens matters more than you’d think. Zippers, especially double zippers, make diaper changes fast and easy. Snaps are reliable and simple but slower. Velcro is the quickest to fasten but can stick to unexpected things and wears out faster. Consider how many diaper changes you’ll do in a night and choose accordingly.
Sizing and fit
Baby costume sizing is notoriously inconsistent across brands. A “0-3 months” label can mean very different things. Look for baggy styles that leave room for layering, and check buy reports on whether a size runs true, big, or small. When in doubt, size up — a slightly loose costume is more comfortable and lets you add a warm layer underneath.
Ear stability
The most common complaint across every bat costume is floppy ears. It’s a design challenge — soft, safe materials don’t hold a pointy shape well. If upright ears matter for your photos, look for hats with wire support or under-chin straps. Otherwise, embrace the flop; it’s still adorable and far safer for a baby.
