For a bat costume you wear black, then add the two shapes that turn black clothes into a bat: wings and pointed ears. Our Women's Fluffy Bat Dress Costume puts the ears on a hood and the wings under each arm in one dress, and our Bat Wings and Ears Headband Set adds both to any black outfit you already own, with wings that open to about 35 inches across.
In the four weeks to October 8, 2026, of the US Google web searches for a bat costume or outfit that showed our store (searches for Batman and other characters, LEGO, and pet costumes excluded), 51% named women or adults, 16% named girls, and 6% named kids, boys, toddlers, or babies; 27% named none of those groups. So this guide goes wearer by wearer, women first. Not set on a bat yet? Our Halloween costumes range and best Halloween costumes guide hold the other looks.

What do women wear for a bat costume?
Women wear a black dress with bat ears and wings built in, or a black outfit with a pair of wings added. The Women's Fluffy Bat Dress Costume is the first kind: black fleece with an oversized hood, attached padded bat ears, attached bat wing details under each arm, and a zip-up front. It comes in six sizes, S to 3XL, so plus sizes are in the range.

The wings for any black outfit
The Adult Black Bat Wings are black felt over a bendable wire frame, about 35 inches across when fully opened. Adjustable elastic shoulder straps form a harness that fits most adults over layered costumes. They come on their own, made to go over a cape, a hood, or a black dress you already own.
Want the ears in the same pack? The Bat Wings and Ears Headband Set pairs plush ears on a headband with poseable wire wings, one size designed to fit most adult frames.
What makes a costume read as a bat?
Pointed ears and wings with a scalloped edge help a costume read as a bat, not just a black outfit. A bat's wing resembles a modified human hand, with a flexible skin membrane stretched between each long finger bone (National Park Service, how bats fly), and a scalloped costume wing is a nod to that finger-and-membrane structure. Ears are the second signal. Townsend's big-eared bat has ears that average a third of its body length (National Park Service, Lava Beds bat species). Big ears are an easy way to make a bat costume read clearly.
How do you shape and wear bat wings?
Loop the straps over each shoulder so the wings sit across your upper back and your hands stay free. The wire frame lets you reshape each wing into a wide spread or a deeper swoop.

Spot clean the wings with a lightly damp cloth, reshape the wire by hand afterward, and store them flat or gently opened so the frame keeps its shape.
What finishes an adult bat look?
Black boots or tights, dark lips, and a smoky eye finish an adult bat look. The FDA advises testing makeup on the arm of whoever will wear it at least 24 to 48 hours ahead, and checking that its colors are FDA approved for that use, which matters most around the eyes (FDA, Halloween safety tips).
What do girls wear for a bat costume?
Girls wear a bat dress with a matching headband, or a velour witch dress with a bat-detailed witch hat.
- The purple dress: the Girls Purple Bat Costume is a layered purple dress with a moon and star print, attached black bat wings, and a matching headband in the pack. Sizes are 3-4 years, S (4-6 years), M (7-9 years), and L (10-12 years).
- The bat witch: the Girls Red Bat Witch Costume and the Girls Gray Bat Witch Costume are crushed velour dresses with an ombre bodice and a layered skirt, plus a bat-detailed witch hat. They run from toddler (3-4 years) to extra-large.
If she would rather be something other than a bat, our girls Halloween costumes guide has other looks.
Which bat costume suits a baby, toddler, or little kid?
A plush onesie suits babies, toddlers, and little kids: the hood lifts off easily for naps and car rides, and the wings detach. Our Boys Bat Onesie Costume is built that way.
The plush onesie, wings and hood included
In the pack: a soft-touch black bodysuit with a bright green printed belly, matching foot covers with anti-slip grip, detachable bat wings with Velcro fastenings, and a removable hood with 3D ears and a plush tuft. It is 100% polyester with elastic cuffs, and it comes in four sizes from 6-12 months to 4-6 years.

All of our kids' products are safety tested by accredited labs. For a toddler who would rather not be a bat, our toddler Halloween costume guide has other looks.
What is the full-body bat costume for kids?
The full-body bat costume for kids is our Kids Vampire Bat Morphsuit, a full-body animal costume in high-detail all-over printing. The pack is the one suit.

The all-over print, built to move
It is 91% polyester and 9% elastane with 4-way stretch, the inner seams are cover-stitched, and a quick-release Velcro hood comes off whenever your child needs it to. Sizes are Small, Medium, and Large, picked by your child's height rather than age.
If your child wants a vampire rather than a bat, our vampire costume guide covers that look.
Can you dress a family or a couple as bats?
Yes: wings and pointed ears are the shared signal, so different bat costumes still read as one set.
- A bat family: wings for the adult, the full-body suit for an older child, and the onesie for a toddler.
- A bat and a vampire: wings or the fluffy dress next to a vampire look; our vampire costume ideas for women and best couples Halloween costumes help you pair them.
- A bigger crew: bats join any night theme next to vampires and witches; our group Halloween costume ideas have more.

Every costume goes through over 30 measurement checks. The women's dress runs S to 3XL and the Morphsuit is sized by height, so check the size guide on the product page before you order. The fabric pieces below are hand wash and air dry, never the washing machine; the wings are spot clean only.
