The best bat costume for kids depends on age: a hooded onesie with velcro wings for a toddler, a dress with wings attached for a girl aged 3 to 12, or a printed vampire bat Morphsuit for an older child who wants spooky. For women, our fleece bat dress runs from S to 3XL. Between 13 September and 17 October 2026, about six in ten UK Google web-search impressions our site earned on bat searches named a child, toddler, boy, girl, or baby, so we start with kids.

Which bat costume suits which age?
Each of our bat costumes and bat fancy dress add-ons covers a different age band, from a toddler onesie up to a women's 3XL dress. The table below lists who each one fits and what comes in the pack. For the wider Halloween line-up for children, see our best kids' Halloween costumes guide and the full kids' Halloween costumes range.
| Costume | Who it fits | Look | What is in the pack |
|---|---|---|---|
| Boys Bat Onesie Costume | Toddlers and young children, four sizes: B1, T1, toddler, and S | Cute: green belly, orange-lined wings | Bodysuit, foot covers, detachable velcro wings, removable hood with ears |

| Adult Black Bat Wings | Adults, one size fits most | Add-on: wings only | Felt wings on a wire frame with shoulder straps |
What is the best bat costume for a toddler?
A plush onesie with a removable hood suits a toddler well, because the bodysuit pulls on quickly over everyday clothes and the extra pieces come off when they get in the way. Our Boys Bat Onesie Costume is a black bodysuit with a bright green printed belly, foot covers with anti-slip grip, wings that attach with velcro, and a hood with 3D ears that lifts off for naps, car rides, or cooling down. It comes in four sizes, B1, T1, toddler, and S, and the product page suggests a thin base layer underneath for warmth.
Cute is closer to the real thing than it sounds. The common pipistrelle, one of the commonest bats in Britain, weighs around 5 grams, the same as a 20p piece, according to the Bat Conservation Trust. For more toddler and baby ideas, our animal costumes guide for kids and adults covers onesies beyond bats.
Which bat costume suits a girl aged 3 to 12?
A dress with the bat wings already attached suits girls from 3 to 12, because there is no separate wing harness to fit or lose. Our Girls Purple Bat Costume runs in four age sizes, and it is the pick for a girl who wants a starry print as well as wings. For a bat look crossed with a witch, our Girls Red Bat Witch Costume sits alongside it, and our witch costumes guide for women and girls covers that hybrid in more detail.
Girls Purple Bat Costume
Our Girls Purple Bat Costume is a layered purple dress with a moon and star print, black bat wings attached across the back, and a matching headband. It is 100% lightweight polyester with a soft lining inside the bodice and an elasticated waist, in 3-4 years, S (4-6), M (7-9), and L (10-12). Black tights or leggings and boots finish the look; they are not in the pack.
Which bat costume looks spookiest for older kids?
Our Kids Vampire Bat Morphsuit is our spookiest-looking bat costume for children, because the whole suit is printed with realistic bat fur and a bat face over the hood. Real vampire bats do exist: there are three species, all found in Central and South America, according to the Bat Conservation Trust, while bats in the UK eat only insects. For a vampire to stand beside your bat, see our vampire costumes for kids, and our kids' Halloween Morphsuits hold the other printed creatures.
Kids Vampire Bat Morphsuit
Our Kids Vampire Bat Morphsuit is 91% polyester and 9% elastane with 4-way stretch, cover-stitched inner seams, and a quick-release Velcro hood. It comes in Small, Medium, and Large, sized by height: the product page says to choose the size that matches your child's current height rather than their age.
Should a bat costume be cute or spooky?
A bat costume can be cute or spooky, and the right one is the look the wearer asks for. The table runs through 4 looks, from soft and bright to realistic, and each one has wings built in or in the pack. For children, that means a nervous 4-year-old and a 10-year-old who wants to scare their friends can both find a bat.
| Look | Our costume | What gives it that look |
|---|---|---|
| Cute and bright | Boys Bat Onesie Costume | Plush fabric, a green belly printed with little bats, a hood with big cartoon eyes |
| Starry | Girls Purple Bat Costume | Purple tulle layers, a silver moon and star print, a bat headband |
| Cosy and dark | Women's Fluffy Bat Dress Costume | Black fleece, a fluffy hood with padded ears, wing panels under the arms |
| Realistic | Kids Vampire Bat Morphsuit | Printed brown and grey fur, a bat face, wing webbing from arm to side |
What bat costume is there for women?
Our women's bat costume is the Women's Fluffy Bat Dress Costume, a black fleece dress with a fluffy hood and bat wing panels under each arm. It is 100% polyester fleece with a zip-up front, padded ears on the hood, and a dipped hem at the back, in six UK sizes: S, M, L, XL, 2XL, and 3XL, so it covers plus sizes too. If you are between sizes, the product page suggests sizing up for comfort. The fleece makes it a cosy bat fancy dress pick for a chilly Halloween night, and spider-web tights and boots finish the look; they are not in the pack.
Our women's costumes and adult Halloween costumes hold the rest of the range.
Can bat wings and ears make a costume on their own?
Bat wings and an ears headband make a full bat costume on their own when you wear them over black clothes you already own. Both of our wing sets use a bendable wire frame that spans about 35 inches, so you can reshape the wings by hand, and both are one size that fits most adults. They also work for a parent walking beside a child in a bat onesie or dress, and our costume accessories hold capes and masks to add.
Bat Wings and Ears Headband Set
Our Bat Wings and Ears Headband Set pairs black polyester wings on a wire frame with plush ears on a lightweight headband. Adjustable straps hold the wings across your shoulders and back, so they move with you. Wipe it with a damp cloth and reshape the wire by hand after cleaning.
Adult Black Bat Wings
Our Adult Black Bat Wings are black felt over an internal wire frame, about 35 inches across when fully open, with elastic shoulder straps that stretch over layered clothes. Pick these on their own if you already have ears or a hood, or add them to a cape for a vampire look. Store them flat or gently opened so the frame keeps its shape.
What can you wear with a bat costume for Halloween?
Wear black tights or leggings, a warm thin layer, and boots with a bat costume, then add a torch or something reflective so a dark outfit is seen after dusk. RoSPA notes that children wearing dark costumes can be less visible to motorists on poorly lit streets, and it advises adding reflective materials and carrying a torch to see and be seen.
- Underneath: a thin base layer under the onesie or Morphsuit, and black tights or leggings under the dresses.
- On the feet: black boots or trainers; the onesie has its own foot covers with anti-slip grip.
- Face paint: use paints marked as safe for skin and try a small amount on the arm first, a step the US FDA recommends, according to CosmeticsInfo.
- To be seen: a torch or reflective tape on a bag or sleeve.
How do bat costume sizes and care work?
Our kids' bat costumes are sized by age or height, the women's dress by UK clothing size, and the wings are one size for most adults. The onesie comes in B1, T1, toddler, and S, the purple dress from 3-4 to 10-12 years, the vampire bat Morphsuit in Small, Medium, and Large by height, and the fleece dress from S to 3XL. Check the size guide on each product page before you order. All of our kids' products are safety tested by accredited labs, and every costume goes through over 30 measurement checks.
Every fabric bat costume here takes a cold hand wash and an air dry, not the washing machine, and both wing sets are spot clean only. Hampshire and Isle of Wight Fire and Rescue Service advises keeping all fancy-dress costumes away from naked flames, which matters with pumpkin candles on doorsteps.
