A black cat costume for kids comes together from four pieces: a black base, pointed ears, a tail, and a painted nose and whiskers. Our Girls Black Cat Costume packs the first three into one set, a plush black jumpsuit with the tail attached plus a cat-ear headband, in five sizes from 3-4 years to 12-14 years. A little face paint adds the fourth.
Girls lead our cat costumes: of the cat-costume orders on our US website from April 22 to October 20, 2026, nearly three in four were for a girls' costume. So girls come first here, and women second. For more animals, browse our kids animal costumes or our kids Halloween costumes guide.
What do you need for a black cat costume?
You need a black base, a pair of pointed ears, a tail, and a cat nose with whiskers. Cats and witches go back a long way: in the Middle Ages, many people saw cats as linked with witches and the devil, according to the Smithsonian, and it's unclear exactly where the superstitions about black cats and bad luck came from (Smithsonian).
What each of our girls' sets puts in the box:
| Costume | Base | Ears | Tail | Also in the pack | Sizes |
|---|---|---|---|---|---|
| Girls Black Cat Costume | Plush black jumpsuit | Headband | Attached to the jumpsuit | Nothing extra | 3-4 years to 12-14 years |
| Girls Glitter Black Cat Dress Costume | Short-sleeved black dress | Headband | Attached to the dress | Glittery skirt overlay | 4-6 years to 12-14 years |
| Girls Purple Kitty Cat Costume | Long-sleeved purple dress with a cat-face print | Headband | Detachable | Purple leggings | 3-4 years to 7-9 years |
None of the three packs includes face paint, tights, or shoes. Black tights or flat shoes finish the jumpsuit, our model wears the glitter dress with black tights and sneakers, and the purple set brings its own leggings.
Jumpsuit or glitter dress: which girls' cat costume suits her night?
Pick the full-length plush jumpsuit for a long walk on a chilly night, and the glitter dress for a party, a school costume day, or a girl who loves to twirl. Both packs include ears and a tail, so her plans and the weather decide it.
The plush jumpsuit for a chilly walk
The Girls Black Cat Costume is a black plush jumpsuit in 100% polyester that covers her torso, arms, and legs, with the tail attached, so there is no separate piece to drop halfway down the street. It has elastic cuffs, and a cat-ear headband completes the shape.
Halloween costumes are usually lightweight, so plan for layers on a chilly night (Franciscan Health). The American Academy of Pediatrics notes that several thin layers keep kids warm and dry (AAP), so a thin long-sleeved top and leggings underneath help on a cold night; measure her over them before you pick a size. Prefer a onesie? We also have a Girls Black Cat Onesie Costume.
The glitter dress for a party or school day
The Girls Glitter Black Cat Dress Costume is a short-sleeved black cat dress with a glittery skirt overlay, sparkly fur trims, an attached tail, and a cat-ear headband. It is stretchy 100% polyester with an elastic waist, so she can move. Add black tights and her own sneakers, the way our model wears it. The pack has small parts, so it is not suitable for children under 3.
Is there a cat costume for girls who want some color?
Our Girls Purple Kitty Cat Costume and Girls Pink Striped Cat Costume give a girl cat ears and a tail in color instead of all black. The purple set stops at 7-9 years; the pink one covers ages 4 to 14.
The purple kitty, leggings included
The Girls Purple Kitty Cat Costume is a long-sleeved purple dress with a cat-face print, leopard-print accents, frilly mesh trims, and glitter details. Purple leggings, a detachable tail, and a cat-ear headband are all in the pack, so it is a full outfit from ears to ankles, in 3-4, 4-6, and 7-9 years.
For pink, the Girls Pink Striped Cat Costume pairs a striped dress with leggings, a fuzzy cat-ear headband, a detachable striped tail, arm warmers, and fingerless gloves.
What size cat costume fits a 5-, 8-, or 10-year-old?
A 5-year-old usually takes the 4-6 years size, an 8-year-old the 7-9 years size, and a 10-year-old the 10-12 years size, because our girls' cat costumes are sized by age band. Check her measurements against the size guide on the product page first; the American Academy of Pediatrics advises making sure a child's costume and shoes fit well (AAP).
- Girls Black Cat Costume: 3-4 years, Small (4-6), Medium (7-9), Large (10-12), and Extra Large (12-14), with elastic cuffs.
- Girls Glitter Black Cat Dress Costume: 4-6 years, 7-9 years, Large (10-12 years), and XL (12-14 years), with an elastic waist.
- Girls Purple Kitty Cat Costume: 3-4, 4-6, and 7-9 years, so a 10-year-old picks the jumpsuit or the glitter dress instead.
Every costume goes through over 30 measurement checks. The jumpsuit's elastic cuffs help it fit different arm and leg lengths within each size.
What do women wear for a black cat costume?
Women wear a black catsuit with a cat-eye mask, or a black dress with ears and a tail added. Cats aren't just for kids: last year, in the NRF's 2025 Halloween survey, 1.6 million US adults planned to dress as one, tied for third behind the witch and the vampire (NRF).
Our Women's Black Cat Bodysuit Costume is the catsuit route: a stretch bodysuit in 100% polyester with a leather-look finish, an adjustable belt with a working buckle, 3/4-length pointed gloves, and a cat-eye mask on an elastic strap. It comes in four sizes, Small to XL. For the dress route, our black dress costume guide builds a cat over a dress you already own, and our adult cat costumes guide covers more grown-up cat styles. For other ideas, see our favorite Halloween costumes for women.
Can a mom and daughter match as black cats?
Mom and daughter match easily as black cats, because the black base ties two different cat costumes together. Three pairings we like from our range:
- Sleek and cozy: the women's black cat bodysuit with the girls' plush black cat jumpsuit.
- Party pair: a black dress with ears for mom, the glitter black cat dress for her.
- A whole litter: add the purple kitty for a younger sister (3-4 to 7-9 years); her ears and tail keep her in the family.

How do you keep a black cat costume visible after dark?
Add reflective tape and carry a light, so an all-black look stays easy to spot. The American Academy of Pediatrics favors bright, reflective costumes, notes that motorists may have trouble seeing trick-or-treaters, and recommends adding glow-in-the-dark elements, reflective tape, or striping to costumes and trick-or-treat bags (AAP). Safe Kids Worldwide suggests glow sticks or flashlights to help kids see and be seen by drivers (Safe Kids Worldwide).
- The tail: both black sets have the tail attached, so wrap a short strip of reflective tape around the end, where it swings.
- The back: add one stripe across the shoulders of the jumpsuit or the back of the dress.
- The bag: stripe the candy bag too, and give her a glow bracelet or a small flashlight to carry.
How do you paint a cat nose and whiskers?
Paint a small black triangle on the tip of the nose, then three whiskers fanning out across each cheek, with a few dots where the whiskers start. Use face paint made for skin: the FDA says color additives in face paints must be approved for cosmetic use, advises trying a dab on the arm for a couple of days to check for a reaction, and notes that some paints are labeled not for use near the eyes (FDA). Take it off the way the label says.
