Overalls are one of my favourite costume bases because the bib is a ready-made canvas. It's a flat panel right at chest height where a patch, a logo or a belly shape sits exactly where people look, and the straps hold up wings, tails and tool belts without any extra harness. Change the shirt underneath, the hat and one prop, and the same pair turns into a plumber, a farmer, a frog or a ghost. They're also comfortable enough for a school parade or an evening on the porch with the candy bowl, and most of the looks below scale from kids to adults with small changes. Here are thirty ways to use the pair you already own.
Fitting the Overalls Before You Add a Single Patch
Every costume below starts with a pair of overalls, and fit decides how comfortable the night will be. A few checks before you decorate save a lot of fiddling later.
- Set the strap length with your costume shirt on. A thick flannel or sweatshirt underneath takes up more room than a tee, and straps that were fine in July pull the crotch up in October.
- Check the side buttons. Overalls with buttoned side openings are far quicker to get in and out of, which matters more than you'd think for small kids at a school party.
- Look at the bib height. A tall bib gives you more space for logos and bellies, while a short one leaves more of the shirt showing, which helps for Mario, Rosie and the striped characters.
- Leave a little ease. Most of these looks want relaxed overalls, and a slightly loose pair hides a thermal layer underneath on a cold night.
If the straps keep sliding off your shoulders, a short piece of ribbon or elastic stitched between them at the back, about shoulder-blade height, holds them in place. It's a two-minute fix that works on kids' and adults' pairs alike.
1. Mario Costume With Blue Overalls
Mario is mostly colour, so the red has to be a true bright red and the overalls a clear blue. The cap is the piece I'd make rather than buy: cut a white felt circle, add a red felt M, and stitch it on with a tight blanket stitch so the edges don't lift after an evening of being pulled on and off. A soft costume mustache needs a skin-safe adhesive; the sticky strip it comes with rarely lasts past the first snack. White gloves and brown boots finish him. Carry a light foam mushroom or a coin, and wear a thermal under the red shirt if you're outdoors.
2. Luigi Costume With Blue Overalls
Luigi uses the same overalls with a green shirt and a green cap carrying a white circle and a green L. He's taller and leaner than his brother, so I'd pick a slimmer fit here and leave the baggy pair for Mario if you're dressing as the duo. A slim mustache and neat brows do the face. White gloves and brown boots or cushioned brown sneakers finish it. A toy flashlight is a nice nod for people who know his ghost-hunting games, and a green foam shell works too.
3. Minion Costume With Denim Overalls
With a Minion, the goggles are the costume; everything else is supporting colour. I make them from two clear plastic cup bases or jar lids painted silver, glued to a strip of elastic, which is lighter than the chunky shop versions and easier to see through. A yellow long-sleeve top, classic blue overalls, black gloves and black shoes are the uniform. Poke a few short black pipe cleaners through a yellow beanie for the sprouting hair. Yellow face paint is optional; on a warm night it creases and transfers onto the beanie, so a yellow eyeshadow wash is the easier route. It's a great costume for groups.
4. Scarecrow Costume With Patchwork Overalls
The scarecrow is where faded, worn overalls finally earn their keep. I hand-stitch patches to the knees and bib with big, visible running stitches in a contrast thread, since uneven, obvious stitching is the whole look. Raffia at the cuffs is softer on skin than real straw, and I tuck it under the cuff edge with a few stitches so it doesn't poke wrists. Put a plaid shirt underneath and a floppy straw hat on top. Draw a stitched smile and a triangle nose with brown liner. A checked scarf adds warmth, and trim the raffia short so you're not leaving a trail across someone's carpet.
5. Farmer Costume With Denim Overalls
Farmer is the costume I point people to when they want zero sewing. Relaxed denim overalls, a red plaid flannel, brown work boots and a straw hat or weathered cap are all closet pieces. Roll the sleeves twice, tuck a bandana into the bib pocket, and hang a pair of work gloves from one strap. A small basket of fake vegetables tells people it's a farmer and not just a weekend outfit. Leggings or a thermal underneath keep you warm outside, and the loose overall fit hides the extra layer.
6. Bob The Builder Costume With Overalls
Bob the Builder needs the yellow hard hat and the checked shirt; the overalls just have to be a medium wash. A toy hard hat sized for adults is usually cheap plastic that perches on top of the head, so I line the inside with a strip of foam weatherstrip tape until it sits level and stays put. Fill a costume tool belt with foam or rounded plastic tools, and skip a real toolbox, which gets heavy within an hour. Rosy cheeks and defined brows give the friendly cartoon face. A rolled-up paper blueprint is the lighter prop, and the little ones at the door will know exactly who you are.
7. Rosie The Riveter Costume With Denim Overalls
Rosie works because of contrast: dark indigo denim, a lighter chambray shirt and that red polka-dot bandana. Roll the sleeves past the elbow and press the roll so it stays crisp. The bandana should be folded into a long band, knotted at the top of the head with the ends tucked, which looks right only if your hair is pinned up first into curls, victory rolls or a high bun. Arched brows, winged liner and red lipstick give the 1940s face. Brown work boots or plain flats. The bent-arm pose is the prop most people actually need.
8. Train Engineer Costume With Striped Overalls
Hickory stripe is the fabric that makes a train engineer read, so this is the costume worth thrifting a striped pair for. Wear them over chambray or red plaid, and add a matching striped cap, a red neckerchief and work boots. Clip a pocket watch chain to the bib button with a split ring so it can't slip out when you bend. A cardboard ticket or a light lantern makes a good prop; if you bring a whistle, save it for outdoors. A thermal underneath handles a cold platform, or a cold porch. The same outfit works for a whole family in matching stripes.
9. Mechanic Costume With Black Overalls
Black or charcoal overalls look like real workwear straight away, which is why the mechanic is one of the quickest costumes here. Put a grey tee or red work shirt underneath and add work boots and a canvas utility belt. Removable fabric tape is fine for the name patch for one night, but on denim it peels at the corners as you move; two or three hand stitches at each corner hold it until you snip them. A few smudges of grey eyeshadow on the cheek and forehead suggest grease without real grime. Carry a foam wrench or a shop rag, not actual tools.
10. Painter Costume With White Overalls
White overalls take fabric paint well, and for a painter, real splatters look better than anything stuck on. If you'd like to keep the overalls for regular wear, cut felt drips in several colours and safety-pin them on from the inside instead. Put a striped or solid long-sleeve shirt underneath and wear canvas shoes you don't mind getting marked. A paper painter's cap sits well over a messy bun. A few streaks of face paint on one cheek, a clean dry brush and an empty bucket finish it. Hang a folded drop cloth from the bib pocket.
11. Gardener Costume With Green Overalls
A gardener is a good fit for green overalls in olive, sage or forest. I'd pair them with something printed underneath, like a floral blouse or a striped tee, so the overalls don't merge into one block of green. Waterproof ankle boots and a floppy sun hat are the practical pieces. The deep bib pockets are the fun part: stuff them with silk flowers, felt leaves and empty seed packets so they spill over the top. A light watering can is the prop, and garden gloves hang from a strap. Leave real soil and plants at home.
12. Pumpkin Farmer Costume With Orange Overalls
Orange overalls are less common in shops, and if you can't find a pair, dye a light denim pair or patch a blue pair with orange fabric. Over a cream plaid shirt or a dark green turtleneck, with brown boots and a straw hat, it reads as a pumpkin farmer rather than a road worker. I stitch felt leaves to the bib and twist green pipe cleaners into curling vines that wrap around the straps. A tiny pumpkin painted on one cheek is enough face. Carry a basket of foam pumpkins that doubles as a candy bucket.
13. Cow Costume With White Overalls
Cow spots on white overalls should be irregular and different sizes, so cut them freehand from black felt. Removable fabric tape will hold them for a short party, but for a long night of sitting I'd tack each spot with a few stitches; tape lifts where denim creases at the hip and knee. A fitted black long-sleeve shirt underneath, black sneakers, an ear headband with soft horns and a few eyeliner spots on the face finish it. A rope tail tacked to the back waistband shouldn't reach the floor. Pick a foam bell if a clanging one would annoy people.
14. Black Cat Costume With Black Overalls
Black denim overalls make a cat costume far more comfortable than a bodysuit, and you can sit cross-legged on the floor in them. A black turtleneck underneath, opaque socks and cushioned ankle boots are the base. Stitch the tail to the back waistband through a few layers so it can't be pulled off by a curious kid. Ears, a drawn nose and whiskers, and winged liner do the face. Black gloves with felt paw pads sewn on keep your hands warm outdoors. A strip of reflective trim on the bib pocket helps if you're out after dark.
15. Bumblebee Costume With Yellow Overalls
A bee in yellow overalls flips the usual colours: the overalls are yellow, and the stripes come from the shirt. A fitted black-and-yellow striped top underneath, black leggings and black boots or sneakers are the base. Wings should be small and fastened to the straps with elastic loops so they ride with your shoulders instead of flapping behind. Antennae on a headband and a tiny bee on one cheek finish the face. If the bib looks too plain, add two or three wide black felt bands across it. A honey-pot prop or a bunch of silk flowers is plenty.
16. Frog Costume With Green Overalls
The frog's eyes are the part I spend time on. Make them from two felt-covered foam half-balls glued to a headband, and set them high on the head; anything lower bounces into your line of sight. Green overalls over a sweatshirt in a different green shade give the frog some depth. A pale green or yellow felt oval stitched to the bib makes the belly. Green sneakers, striped socks and a small curved painted smile at the mouth corners finish it. Webbed felt cuffs over the hands are optional, and a plush lily pad is the obvious prop.
17. Garden Gnome Costume With Red Overalls
Red overalls make a gnome look different from the usual tunic version. Put them over a blue or green long-sleeve shirt with striped socks and brown boots. The tall red felt hat should be soft enough to bend; I stuff only the bottom few inches with fibrefill and leave the tip floppy, which also stops it catching on doorframes. Adults can wear a soft white beard, or skip it for rosy cheeks and a round nose. Felt mushrooms and silk flowers in the pockets dress the bib. It's a natural costume for a backyard group with gardeners, frogs and bees.
18. Clown Costume With Colorful Overalls
Baggy, bright overalls are the ideal clown base, and the looser the fit, the better the silhouette. Red, blue, yellow or patchwork pairs all work over a striped long-sleeve shirt. I'd skip the giant clown shoes and wear bright socks with clean high-tops, since oversized shoes are a trip hazard on stairs. A curly coloured wig or high pigtails, a small red nose, round blush and a simple curved smile keep it friendly. Sew a few pom-poms to the bib so they bounce when you walk, and add a bow tie. Avoid masks and scary makeup.
19. Loonette Costume With Red Overalls
Loonette is a lovely one for anyone who grew up with her show. Loose rust-red overalls over a black-and-white striped shirt, striped tights and black flats or Mary Janes are the outfit. The dark curly wig goes into two high pigtails with colourful ties, and the small blue bowler hat pins between them with two crossed bobby pins through the brim. A round red clown nose, rosy cheeks and white gloves finish her. Since the overalls are baggy, keep the shirt and tights fitted so the cartoon proportions come through. A small cloth doll is a sweet extra.
20. Chucky Costume With Striped Overalls
Chucky in overalls keeps the doll recognisable without any of the horror makeup. Blue overalls with colourful toy-themed patches, a bright striped long-sleeve shirt and red sneakers are his look. A short orange wig in a messy bob is easier than temporary copper hair colour, which tends to rub off on collars. Add freckles and strong brows, and leave out scars and blood entirely. Carry a toy box or building blocks instead of anything sharp. Stitch the patches on flat rather than using stiff iron-ons on the bib, so the overalls still bend when you sit.
21. Pearl Farm Girl Costume With Denim Overalls
The Pearl farm-girl look depends on the blouse as much as the overalls. A cream blouse with puffed sleeves or a small collar under medium-blue denim gives the period shape, and a slightly high-waisted vintage pair of overalls makes it stronger. Neat braids tied with pale blue ribbons are the hair. Defined lashes, rosy cheeks and red lipstick give it polish. Brown lace-up boots and neutral socks finish it, and a basket of fake corn or silk flowers keeps the prop light and not frightening. A cardigan on top handles a cool night without hiding the blouse.
22. Wreck-It Ralph Costume With Brown Overalls
Wreck-It Ralph is about scale: everything should look a size too big. Brown overalls over an orange-red plaid shirt with the sleeves rolled unevenly, a wide fabric belt, and the biggest brown boots you can walk in. Boot covers cut from brown fleece and elasticated over your sneakers are a comfortable cheat. Messy, upright dark hair, thick brows and a broad nose contour give the face. Oversized foam gloves look right but slide off easily, so tack a strip of elastic inside each cuff. A cardboard gold medal on a ribbon is his prop.
23. Mabel Costume With Denim Short Overalls
For Mabel, the sweater is the costume. Knit or sweatshirt, it should be bright and oversized with a handmade-looking motif like a rainbow or shooting star; I cut the design from felt and stitch it on with big, cheerful stitches so it looks like she made it herself. Denim short overalls go over it, with colourful tights, white ankle socks and flats or sneakers. Long brown hair with a wide headband, pink blush and a glossy lip. A plush pig is the prop people recognise. Decorate the bib with pins that have locking backs.
24. Vintage Doll Costume With Corduroy Overalls
Corduroy overalls give a vintage doll a softer, nubbly texture than denim, and rust, mustard, burgundy or forest green all suit it. A white blouse with a round collar and puffed sleeves underneath, knee socks and Mary Janes are the outfit. Curls or pigtails with velvet ribbons. Paint the face with round blush, drawn lower lashes and a small rose lip. The wind-up key is the detail people notice; I cut it from two layers of cardboard glued together, paint it, and pin it to the back waistband so it doesn't flop. Hand-tack lace trim to the bib for a night.
25. Woodland Elf Costume With Brown Overalls
A woodland elf in brown or moss overalls looks earthy and storybook, especially over a cream peasant blouse or a fitted forest-green shirt. Striped tights or textured socks and soft brown ankle boots keep it comfortable. Removable ear tips, a leafy headband and a few tiny silk flowers in loose braids make the elf. I sew felt leaves and acorns to the bib pockets with several stitches each, since glued felt pops off the curve of a pocket. Golden shadow, freckles and a touch of green near the temples. A small lantern or a rolled paper map is the prop.
26. Flower Pot Costume With Brown Overalls
The flower pot is a clever one because the bib is literally the top of the pot. Stitch a row of silk flowers along the top edge of the bib, wiring the stems flat so the heads stay below your chin. A green long-sleeve shirt and green tights or pants underneath play the stems and leaves. A light brown foam band wrapped at the hips suggests the rim; secure it with hook-and-loop tape so you can take it off to sit. A leafy headband and petal shapes painted around one eye finish the face. Carry a small watering can.
27. Strawberry Costume With Red Overalls
For a strawberry, red overalls need seeds and leaves. Cut small teardrop seeds from pale yellow felt; fabric adhesive holds them for an evening, but I'd stitch the ones on the knees, which flex the most. A green felt collar cut in a leaf shape around the neckline is the detail that makes it read as fruit. Green socks with red sneakers, a leafy headband over a bun, pink blush and a tiny strawberry on one cheek finish it. Skip full red face paint, which feels heavy and smudges. A basket of foam berries is the prop.
28. Lumberjack Costume With Denim Overalls
The lumberjack is the warmest costume on this list, so it's my pick for a cold, outdoor night. A red-and-black buffalo plaid flannel under dark overalls gives strong contrast, and thick socks, lace-up boots, a knit beanie and work gloves are all practical too. A soft beard is optional; warm blush and filled brows work without it. Add a faux-shearling vest if it's really cold. Carry a cardboard log or a bundle of foam firewood instead of anything with a blade. The overalls leave room for a thermal underneath.
29. Country Music Singer Costume With Overalls
A country singer costume is where overalls get some sparkle. Flared or fitted pairs work over a western blouse, a gingham top or something with shine. I'd add rhinestone trim to the bib with a few stitches rather than glue, since glued stones pop off denim as soon as it creases. Embellished ankle boots, a bright neck scarf and big curls or a high ponytail under a cowboy hat finish the look. Carry a toy microphone or a cardboard guitar on a fabric strap. Build your own singer from familiar details instead of copying one real performer.
30. Overall Wearing Ghost Costume
This is the gentlest ghost I know, and it's built on pale blue or faded white overalls over a white long-sleeve shirt. Wispy strips of white tulle stitched at the straps and pockets drift as you walk; keep them short enough not to tangle. A long white or silver wig and pearl-white makeup with grey eyeshadow replace the sheet, so you can see properly all evening. White sneakers, grey socks and a loose white scarf finish it. A sign reading 'Friendly Farm Ghost' tells people what you are with a smile.
Patches That Hold Up to Sitting, Kneeling and Climbing
Denim is tough and forgiving to work on, which is why so many of these costumes add patches, logos, spots or seeds. How you attach them depends on where they go and whether you want the overalls back afterward.
On the bib
The bib barely moves, so almost anything works here. Fabric tape and fabric glue hold for one night, and iron-on patches bond well because cotton denim takes a hot iron happily. Iron-ons are permanent, though, so use them only on a pair you've given over to costumes. For a pair you want back, a few hand stitches at each corner of a felt patch are enough.
On the knees and hips
These spots crease every time you sit or bend, and tape and glue lift there first. I stitch anything on the legs all the way round. One mistake I see often: when sewing a patch onto a leg, slide a piece of cardboard or a magazine inside the leg first, so the needle can't catch the back layer and stitch the leg closed.
Undoing it all on November 1
Hand stitches snip out in minutes and leave only tiny holes that close up in the wash. Tape residue comes off denim with a little dish soap and a soft brush. Glue is the one that stays, so keep it for felt-on-felt jobs like hats and props rather than the overalls themselves.
One Pair of Overalls, Thirty Different Shirts
Most of the work in these looks is done by what goes under and on top of the overalls: the shirt colour, the hat and one prop. Classic denim covers plumbers, farmers, builders and scarecrows, and coloured pairs open up frogs, bees and strawberries. Check your closet and a thrift store before buying, and keep a reel of thread and a needle handy, since a few hand stitches hold patches better than tape and snip out the next morning. Choose the version you can walk, sit and stay warm in, and the overalls will do the rest.
