Most girls I dress for Halloween want two things at once: to look like the character and to keep moving all evening. The thirty ideas below run from classic witches and storybook heroines to animals, fantasy looks, bright colour costumes and grown-up jobs, and each one is planned head to toe with clothes, hair, makeup, shoes and small accessories. A good number come together from her own wardrobe, a thrift run or a few craft supplies, and the rest can start from a shop-bought piece you adapt. I keep the layers soft, the shoes practical and the props light, because a school parade, a party and a trick-or-treat walk are three different tests. There's a fairy, a detective and plenty in between, so a quiet six-year-old and a dramatic ten-year-old can both find hers.
Wings, Tails and Capes That Last Past the School Gate
Most kids' costumes don't fail at the clothes. They fail at the add-ons: a wing strap slips off a shoulder, a tail gets sat on, a hot-glued star drops off the hat by the third house. I attach everything that sticks out with three questions in mind. Will it stay on when she runs? Can she take it off herself? Could it hurt anyone in a crowd?
- Wings: elastic straps that cross at the back hold far better than two simple loops. Try them on over the warmest layer she'll wear, because a coat changes the fit.
- Tails: fix them with a snap or elastic loop at the waistband, never sewn to the leggings. She will want to sit, and a tail she can unclip is a tail that survives the night.
- Capes: use shoulder tabs or hook-and-loop at the collar, not ties at the throat, and cut them above the knee so they can't slide under her feet on stairs.
- Headbands: a bobby pin through each side stops ears and horns sliding forward. Thin, padded bands hurt less behind the ears over a long evening.
- Glue: hot glue turns brittle in cold air and lets go, so for anything worn outdoors I stitch, or use fabric glue that has cured overnight.
Give every piece a gentle tug before she leaves the house. If it comes off in your hand, it will come off on the walk.
1. Girls Classic Witch Costume With Purple Cape
A witch is the costume I suggest most for a girl who doesn't like scary, because the purple keeps it friendly. Start with a knee-length black dress, or a black top over a soft tulle skirt, then add purple-and-black striped tights, a velvet cape and buckled ankle boots she can actually walk in. The wide-brim pointed hat is what makes it read as a witch from down the street, so check it before anything else: many are cut for adults and slide over the eyes, and a strip of felt inside the band or a thin elastic under the chin fixes that. Loose waves or two low braids stay neater than a ponytail under the hat. Purple eyeshadow, rosy cheeks and a little cosmetic shimmer are plenty. On a cold night, a fitted black shirt and leggings disappear underneath, and a few stars stitched to the brim make the hat hers.
2. Girls Sparkling Fairy Princess Costume
Fairy princess costumes go wrong in the wings more often than the dress. I look for translucent wings on a soft elastic harness, not the stiff wire kind that pokes the back of the neck after an hour. Underneath, a pale dress with a lined skirt is kinder than bare tulle, which scratches the legs, and white tights add warmth without fighting the pastels. A ribbon-wrapped wand, sparkly flats and a small flower crown finish her. A braided half-up style holds the crown best. Washable glitter gel along the part looks magical but travels, so expect to find it on pillows for a few days. Keep the face light with pink cheeks, a touch of shimmer and tinted lip balm. If the dress is too formal for walking, a leotard and tulle skirt does the same job and lets her sit, dance and carry a treat bucket without fuss.
3. Girls Black Cat Costume With Tulle Skirt
This is the costume I'd send a nervous parent toward, because almost every piece is already in a drawer. A long-sleeve black top, black leggings and a layered tulle skirt make the base; a soft cat-ear headband, a flexible fabric tail and black sneakers do the rest. Two high ponytails sit just behind the ears and help the headband stay put. For the face I use skin-safe face paint for a small black nose, three whiskers each side and a gentle winged eye, and I keep the lines thin, because thick black paint smudges onto everything once a child rubs her nose. A collar with a lightweight felt tag is a sweet extra. All-black disappears at dusk, so reflective ribbon on the skirt hem or treat bag matters more here than in most costumes. Skip rigid tails; they whack other kids in a crowded classroom.
4. Girls Wednesday Addams Costume With Braids
Wednesday works because the shape is so simple: a modest black dress with a crisp white collar and cuffs, opaque black tights and flat lace-up shoes. The braids carry the character, so give them time. A clean center part and two long, tight braids read from across a playground. For shorter hair, a dark wig with the braids already in gives the same outline, though inexpensive ones shed and tangle at the nape, so brush it gently with a wide comb before she wears it. Keep makeup low-key with a pale foundation effect, softly defined brows and muted pink lip balm. A small black book is a better prop than a toy cello case for most kids, since the case gets put down and forgotten. I'd pick a dress with a little stretch so she can slouch in her chair, which is very much in character anyway.
5. Girls Dorothy Costume With Red Shoes
Dorothy is a fan-made costume I like for younger girls because every piece is soft. Layer a blue gingham pinafore over a short-sleeve white blouse with puffed sleeves, then add white ankle socks and red glitter flats. Those shoes are the detail people look for, and flats mean no heels to wobble on. Glitter shoes shed on carpets, so a light coat of clear sealer the night before helps hold it. A center part and two low braids tied with blue ribbons finish the hair, and rosy cheeks with tinted lip balm are all the makeup she needs. A wicker basket lined with blue fabric doubles as her treat holder, and a small plush dog peeking out tells everyone who she is before she says a word. When October turns cold, a white cardigan goes over the blouse without breaking the look.
6. Girls Alice In Wonderland Costume With Blue Dress
The blue of Alice's dress matters more than anything else, so I match the shade first and add the rest after. A knee-length short-sleeve dress with a clean white apron over the front, white tights, black Mary Janes and a black ribbon headband make this fan-made version. Blonde hair can stay straight or take a soft curl. For other hair colours a blonde wig gives the familiar outline, but have her wear it around the house first, as some kids can't stand the itch at the hairline. Light pink blush and lip balm are enough. A small plush rabbit or a toy pocket watch is easy for little hands to hold. Tie the apron with a double knot at the back and trim the strings if they hang below the hem. It's a tidy costume, which suits school celebrations and library events where messier looks feel out of place.
7. Girls Little Red Riding Hood Costume
The red hooded cape is the whole costume here, so that's where I'd spend. Underneath, a white blouse with a red or gingham knee-length dress, opaque tights and flat black boots keep her warm and practical. Hoods are the problem: a deep one blocks side vision, so I pin it back a little or choose one that sits on the crown of the head. Soft curls or two low pigtails tuck under it neatly. Rosy cheeks and a natural lip colour suit the outdoorsy feel. A small wicker basket lined with a checked napkin beats an oversized prop and holds treats or her gloves. Pick a cape that ends between waist and knee and closes with a snap. Long ties at the throat get tugged by friends, and they're not something I want near a child's neck.
8. Girls Mermaid Costume With Iridescent Skirt
A true fishtail skirt is the classic mermaid mistake for kids, because she can't climb a step in it. I build this one on an iridescent, scale-print stretch skirt that flares below the knee, with sea-coloured leggings underneath and a lavender or aqua long-sleeve top above. Metallic sneakers beat flats if she'll be walking several blocks. Loose waves or a bubble braid suit the character, and a temporary colour extension clips in with no dye involved. Pearly face stickers and a little blue eyeshadow with shimmer suggest the sea without covering her face; stickers lift with sweat, so press them on only after any lotion has soaked in. A shell headband and a light foam starfish wand finish her. Check the hem while she's in her shoes, and a cropped sheer blue cape adds movement while keeping her hands free for games.
9. Girls Rainbow Unicorn Costume
Unicorn requests come every year, and the trick is a horn that stays upright. A padded horn on a headband with soft ears is far better than a mask, and I slide a bobby pin through the band at each side so it doesn't tip forward. The base is a white sweatshirt dress, or a white top with leggings for an active kid. Over that go a rainbow tulle skirt, pastel leg warmers and white sneakers. A high ponytail with clip-in colour strands is fun; washable hair chalk works too, but it rubs onto collars and car seats, so I save it for kids in darker tops. Pastel eyeshadow, rosy cheeks and small cosmetic stars near the temples are plenty, and a detachable yarn tail rounds it out. If the night is cool, a white jacket replaces the sweatshirt and nothing else needs to change.
10. Girls Rainbow Costume With Cloud Details
This one makes a good no-sew project to do with her. Layer a multicoloured tulle skirt over a white long-sleeve top, or start with a striped rainbow dress if you already own one. For the skirt, I knot strips of coloured tulle around a wide elastic waistband; cut each strip twice the finished length and fold it over the elastic, and the fullness doubles. Small felt clouds stitched near the shoulders or waistband stay put better than glued ones, which peel once the fabric flexes. White tights, rainbow socks and clean white sneakers go underneath, two high buns with colourful ribbons go on top, and light blue eyeshadow with pink cheeks and tiny cosmetic dots finishes the face. A cloud-shaped treat bag is a handy prop. Trim any ribbon that hangs past the knee so it can't catch on her shoes.
11. Girls Monarch Butterfly Costume
Wings are the first thing I measure on any butterfly. They should be no wider than her arm span, or she'll clip classmates and door frames all afternoon, and the elastic shoulder straps need to sit snug without rubbing under the arms. With that settled, the rest is quick: a black leotard or fitted long-sleeve shirt, black leggings, an orange tulle skirt and a soft antenna headband, plus black sneakers or ankle boots for outdoor walking. A smooth bun or two small space buns sit nicely under the antennae. Orange eyeshadow, a thin line of black liner and a few white cosmetic dots around the eyes echo the white spots on a real monarch's wing edges, which is the detail grown-ups notice. A small flower wand is a light, harmless prop.
12. Girls Bumblebee Costume With Striped Dress
Stripes do all the work on a bee, so even a plain black shirt reads once the bands are on. If you can't find a black-and-yellow striped dress or sweater, cut wide yellow felt bands and attach them with removable fabric tape. I tack the ends with two stitches, because tape alone lifts at the sides after a few hours of wriggling. Wear it over black leggings with yellow socks, black sneakers, translucent wings and a padded antenna headband. Two high buns echo the antennae. Keep the face sunny with yellow eyeshadow, rosy cheeks and a touch of shimmer, and let her carry a honey-pot treat bucket or a light flower. Keep the wings compact for doorways and crowded events. A black cardigan adds warmth without hiding the stripes.
13. Girls Ladybug Costume With Red Tutu
A ladybug is the easiest costume for a child to make her own, because she can place the spots herself. Pair a black long-sleeve top and black leggings with a red tulle skirt, then add small red-and-black wings and a soft antenna headband. Round black felt spots go on the skirt. Glue barely grips open tulle, so I use a quick running stitch or removable adhesive dots on a lining layer, and the clothes go back to everyday wear in November. Black ballet flats or sneakers keep it comfortable. Pigtails tied with red ribbons look sweet, and red blush, a fine line of liner and tiny black dots at the outer eye corners finish the face. A green felt leaf or flower-shaped treat bag is the prop I'd pick.
14. Girls Woodland Fox Costume
Fox costumes look cosy, and that's the point: this is one of the warmest choices on the list. Start with a rust-coloured sweater dress or an orange hoodie with brown leggings, then add a cream felt chest panel, a fluffy fabric tail, pointed ears and brown lace-up boots. The chest panel is where homemade versions fall flat. Cut it as a soft V and stitch it on rather than gluing, so it moves with the knit. Soft waves or side braids sit well under the ears. Washable face paint gives a small black nose and delicate whisker dots, and orange blush blended high on the cheeks hints at fur. A fabric leaf garland makes a light prop. Attach the tail with a snap or elastic loop at the waist so she can unclip it before sitting down at a desk.
15. Girls Astronaut Costume With Silver Boots
Astronaut is a full-coverage costume, which makes it one of my picks for a cold walk. A white utility-style jumpsuit, or a matching white sweatshirt and joggers, gets space-themed fabric patches, a silver belt and metallic boot covers over white sneakers. Iron-on patches hold far better than stick-on ones on fleece. A low bun or braids fit under a lightweight helmet or padded headset. I avoid sealed helmets entirely, because they muffle hearing and fog up, and a child who can't hear a car isn't safe on the street. Silver eyeshadow and small star stickers make the face fun. A compact backpack decorated as a life-support pack is my favourite prop, since it carries her treats too. Reflective tape on the sleeves and legs adds detail and gets her seen at dusk.
16. Girls Mad Scientist Costume
The lab coat is the only piece most families need to find, and a thrifted adult-size one is often the cheapest route. Roll the sleeves twice and cinch the waist with an adjustable belt so it doesn't swamp her. Underneath go a bright T-shirt and patterned leggings, with colourful rubber gloves, safety-style glasses and closed-toe sneakers. A frizzy gray-and-white wig gives the wild hair, though gently teasing her own hair works too and itches less. Bright eyeshadow and a small streak of gray face paint on one cheek suggest an experiment gone sideways. Plastic test tubes filled with coloured water look great, but tape the caps shut and make sure nothing is glass; a leak down a white coat ends the fun quickly. A clipboard with a cardboard formula chart is the mess-free option.
17. Girls Veterinarian Costume With Plush Animal
A gentle costume for animal lovers, where the plush animal does most of the explaining. Teal or purple scrubs over a fitted long-sleeve shirt and supportive white sneakers make the base. Scrubs run boxy on kids, so size down or take up the trouser hems with a few stitches. A high ponytail or tidy bun keeps hair out of her face, and lip balm with a little blush is all the makeup required. Hang a toy stethoscope around her neck and let her carry a plush dog or cat in a small open-top carrier. A handmade name badge and fabric paw-print patches give it personality. I'd leave heavy bags at home; a light clipboard with a pretend checkup sheet explains the costume at a school parade and is easy to hold.
18. Girls Firefighter Costume With Reflective Stripes
A firefighter costume is built for the outdoors, which is why I like it for trick-or-treating. Black cargo pants and a black or navy long-sleeve shirt go under a tan firefighter-style jacket with bright reflective stripes, and those stripes add real safety, not only decoration. Sturdy black boots or sneakers finish the base. Low braids fit under a lightweight plastic helmet, and I keep makeup natural so her face stays clear and visible. A coiled yellow fabric rope or a small plush rescue dog makes a safe prop. Skip heavy pretend equipment that drags on a small arm. Her chosen firefighter name across the back of the jacket makes it personal; iron-on letters survive the wash, while glued felt ones tend to peel off synthetic jacket fabric.
19. Girls Detective Costume With Plaid Coat
Older girls who find most costumes babyish usually say yes to this one. A plaid cape coat or checked blazer over a white blouse and dark trousers, a matching cap, patterned socks and brown lace-up boots give a smart storybook-sleuth look. A low ponytail or a side braid tucked behind the ears keeps her neat, and natural makeup with softly defined brows is enough. The props are the fun part: a plastic magnifying glass, a small notebook and a pencil, plus a cardboard evidence folder that quietly holds party papers or candy. Magnifying glasses get dropped constantly, so I add a short wrist loop of cord. On cooler nights a sweater slips under the coat.
20. Girls Cowgirl Costume With Denim And Boots
Most of a cowgirl comes straight out of the closet. Pair a checked button-down shirt with jeans or a knee-length denim skirt over leggings, then add a brown vest, ankle boots, a bandana and a western-style hat. The hat is the piece to check. Kids' cowboy hats often sit low and block the view, and a strip of foam tape inside the band makes one snug in a minute. Two braids look polished under it. Peach blush and natural lip balm keep the face simple. A small plush horse or a soft cord rope loop is a safe prop, and a decorative belt with a cardboard star badge adds another western detail. Indoors she can drop the vest and still look the part.
21. Girls Friendly Pirate Costume
I keep pirates friendly for kids by leaning on clothes rather than weapons. A red-and-white striped shirt with loose black cropped pants, or a layered black skirt over leggings, takes a fitted vest, a red waist sash, striped socks and flat lace-up boots. A soft head scarf is comfier than a rigid hat and won't blow off on a windy street. Textured waves or a side braid with small ribbons suit the look, and bronze eyeshadow with rosy cheeks gives a sun-at-sea glow. Carry a rolled paper treasure map or a light cardboard telescope. I'd skip the eye patch on a trick-or-treat walk, since covering one eye wrecks depth perception on kerbs and steps. Gold-coloured buttons and removable patches make ordinary closet pieces look far more detailed than a boxed set.
22. Girls Superhero Costume With Blue Cape
Inventing her own hero is half the fun, and it frees you from licensed costumes. A bright long-sleeve top and matching leggings in her favourite colour get a contrasting knee-length cape, soft wrist cuffs, a fabric belt and supportive high-top sneakers. Let her design the chest symbol and cut it from felt, then attach it with removable tape or a few stitches. A secure ponytail keeps hair off the cape. Colourful eyeshadow and cosmetic stars at the temples replace a mask, a good swap because masks cut side vision. A small foam shield is a safe prop. The cape rule I never bend: above the knee, fastened with shoulder tabs, never tied around the neck.
23. Girls Ballerina Costume With Pink Tutu
Real ballet slippers are slippery on pavement, so for Halloween I swap them for ballet-style flats with nonslip soles. A soft leotard with a layered tutu and opaque tights forms the base. Pull the hair into a smooth bun with a ribbon or a small sparkly comb; a bun net and plenty of pins keep it in place through a long evening. Pale pink blush, a touch of eyeshadow and tinted lip balm give a stage feel without heavy makeup. A ribbon wand makes a pretty prop, and a wrap cardigan comes off once she's indoors. Before the day, sit her down in the tutu and feel the waistband yourself. Scratchy sequins or stiff net against the skin are what make kids miserable by the second house.
24. Girls Pop Star Costume With Metallic Jacket
Pop star suits girls who want sparkle and room to dance. A plain top goes with a sequined skirt, metallic leggings or comfortable wide-leg pants, then a bright cropped jacket, high-top sneakers, fingerless fabric gloves and star-shaped sunglasses. Sequins are the comfort risk: unlined sequin fabric scratches the inner arm and waist, so I only use pieces with a soft lining. A high ponytail with colourful extensions gives the hair height. Shimmering eyeshadow, glossy lip balm and cosmetic face gems make a stage finish, and the gems stay put best on clean, oil-free skin. A light toy microphone or cardboard concert pass makes the prop. For a girl who'd rather be comfy, a sweatshirt and joggers swap in easily, with the jacket and glasses kept on top.
25. Girls 1950s Poodle Skirt Costume
A felt circle skirt is one of the easiest things to sew for a costume, since felt doesn't fray and needs no hem. Cut the waist to her measurement, add a poodle appliqué, and tuck in a white or pastel short-sleeve top. A narrow neck scarf, white ankle socks and black-and-white saddle shoes or simple sneakers finish the 1950s outline. A high ponytail tied with a ribbon is the classic hair, and rosy blush with pink lip balm is enough on the face. A lightweight cardboard record makes the prop, and a fitted cardigan adds warmth that suits the era. I keep the skirt around knee length so stairs, classroom chairs and party games give her no trouble.
26. Girls 1970s Disco Costume With Flared Pants
Flared pants are the heart of a disco costume, and their length decides whether she trips. I hem them to just brush the top of her shoe and choose a stretchy metallic or patterned fabric so she can sit cross-legged. A fitted long-sleeve top, a sleeveless vest, platform-look sneakers with flat soles, oversized sunglasses and a sparkly headband finish the outfit. Real platforms are a turned ankle waiting to happen on a dark kerb, so the flat-soled version is the one I'd buy. Bouncy curls or a big high ponytail give the hair volume. Colourful eyeshadow and shimmer across the cheeks suit the decade. A light cardboard disco ball or toy microphone works as the prop, and a few silver stars on the vest catch the light when she moves.
27. Girls 1980s Aerobics Costume
Of all the decade costumes, this is the one kids can actually run in. Bright leggings go under loose athletic shorts or a fitted leotard, with an oversized off-the-shoulder sweatshirt over a tank top, leg warmers, colourful wristbands and supportive white sneakers. The easiest off-shoulder neckline comes from cutting the ribbed band off an old sweatshirt; fleece knit won't unravel, so it needs no finishing. A high side ponytail with a large scrunchie nails the hair. Blue or purple eyeshadow, pink blush and glossy lip balm finish the face. A small cardboard cassette player is lighter to carry than a foam mat. Layered neon makes the theme clear, and breathable fabric keeps her comfortable at a warm indoor party.
28. Girls Friendly Scarecrow Costume
Scarecrows are cosy and forgiving, which makes this a good costume to build together. Denim overalls go over a plaid shirt, with fabric patches on the knees and pockets, brown boots and a floppy straw-style hat. I tie small pieces of raffia loosely at the wrists rather than tucking real straw anywhere; straw scratches skin and leaves a trail through every house you visit. Braids or pigtails fit under the hat. Orange blush, a painted triangle nose, freckles and short stitched lines near the mouth make friendly scarecrow makeup. A fabric sunflower or tiny plush crow is a sweet prop, and a fitted thermal shirt under the plaid adds warmth without changing the harvest colours.
29. Girls Skeleton Costume With Tulle Skirt
A skeleton stays cheerful when the bones are clean and graphic rather than gory. White felt bones look crisp on a black shirt, but felt glued to stretchy knit tends to pop off, so I stitch around the edges or paint the bones on with fabric paint instead. Black leggings and a gray or white tulle skirt soften the look, and black sneakers with white laces keep the palette consistent. Two buns tied with white ribbon work for hair. Keep the face simple with a small black nose, white highlights and gentle cheek lines in skin-safe face paint, nothing realistic. Glow-reflective tape along the sleeves and legs echoes the bones and gets her noticed in the dark. Test that the paint comes off easily a few days before the night itself.
30. Girls Glam Vampire Costume With Red Cape
A glam vampire is the right amount of spooky for a girl who wants to look a bit grown-up. A black velvet dress or a black blouse with a knee-length skirt, a red-lined cape, opaque tights and flat black ankle boots form the base. Polished curls or a braided crown suit the character. Pale foundation, plum eyeshadow, softly defined brows and a deep berry lip give the theatrical feel without blood or wounds. Berry colour transfers onto cups and sleeves, so blot it and press a little translucent powder over the top. A red jeweled necklace and a small antique-style book are the accessories. Hard plastic fangs often make kids lisp and drool, so I leave them out. Keep the cape above the ankles and fastened securely at the shoulders so she can walk, sit and collect treats safely.
Gentle Makeup for Small Faces, On and Off
Nearly every costume here uses a little face paint or shimmer, and young skin reacts more readily than adult skin. I only use products made for skin, never craft paint or markers, and I patch-test on the inner wrist a day or two before Halloween. If any redness shows up, that product stays in the drawer.
Making it last through the evening
Start on clean, dry skin with no thick lotion underneath. Build thin layers rather than one heavy coat, then press a light dusting of translucent powder over cream paint so it sets and transfers less onto collars and capes. For the youngest kids, keep lines on the nose and cheeks, well away from the eyes. A cotton bud and a small mirror in her treat bag handle touch-ups.
Taking it off at bedtime
Water-based paint lifts with warm water and a mild cleanser. Cream paint comes away more easily if you massage in a little baby oil or cleansing balm first, then wash. Glitter takes patience: dab it off with a piece of tape before any water touches it, or it spreads across the whole face. Finish with a plain moisturiser, especially if her cheeks look pink from rubbing.
One Costume, Three Very Different Events
A school parade, a party and a trick-or-treat walk ask different things of the same outfit. For school, check the rules first, since some schools don't allow masks, toy weapons or face paint, and wide wings struggle in a classroom. Parties are about heat; indoor rooms warm up fast, so a costume with a removable layer, like the fox hoodie or the witch's cape, helps. Outside, she needs shoes she has already worn, reflective tape on dark costumes and a small glow stick to carry. The ideas on this list that handle all three best are the simple ones built on her own clothes.
Let Her Add the Last Detail
Every costume above, from the witches and storybook girls to the animals and career looks, depends as much on comfort and visibility as on the character she picks. A few days before Halloween, I have her walk, sit and climb stairs in the full outfit, then fix whatever bothers her: a long hem, slippery soles, stiff wings, a headband that pinches. Skin-safe makeup, soft props, a warm layer and a strip of reflective tape cover most of what a long evening throws at her. Then hand the final touch over to her. A favourite colour, a handmade badge or a decorated treat bag is what makes a familiar costume feel like her own.
