Two fish, two colour stories, and almost no sewing: that's why I keep coming back to Nemo and Dory when someone asks me for a pair costume that reads from across a street. Nemo is orange with white bands edged in black, Dory is royal blue with black markings and a yellow tail, and once those two palettes stand side by side people get the joke before they see a single fin. Most of the versions I put together start from a hoodie, a dress, a tutu or plain leggings, with felt fins and a fish-eye headband doing the character work. Below you'll find solo looks, couples, siblings, family groups, a maternity option and even a pet version. Pick the ones that suit your weather and the people you're dressing, then adjust the layers from there.

Felt Bands That Stay Flat on a Stretchy Hoodie
Almost every Nemo on this list depends on white bands edged in black, and they're the first thing to go wrong. Felt doesn't stretch and a hoodie does, so a band glued flat on the table buckles the moment someone puts their arms up. I measure the garment while it's being worn, then cut each band a little longer than the measurement and attach it in a slight curve so it sits like a stripe on a round body.
Here is the order I work in for a clean result:
- Cut the white band about two inches deep, then cut two black strips roughly a quarter inch wide for the borders.
- Glue or iron the black borders onto the white felt first, flat on a table, so the edges line up neatly before the band goes anywhere near the hoodie.
- Pin the finished band to the hoodie while the wearer has it on, with their arms slightly raised.
- Attach it with large running stitches or a few safety pins from the inside. Fabric glue on knit tends to crack along the band when the fabric stretches.
- Fit fins last, and check that the right fin is the smaller one when the wearer faces you.
Dory is more forgiving. Her black markings can be loose, swooping shapes, and nobody notices if one side differs from the other. Give the yellow most of your attention. It washes out in photos taken at night, so I use a saturated lemon felt rather than pale butter yellow, and make the tail panel bigger than looks necessary in daylight.
1. DIY Nemo Costume With Orange Hoodie

The orange hoodie is where I start almost every homemade Nemo, because it already gives you the colour, the warmth and a hood to hang the face on. Add orange joggers or leggings and plain black sneakers. Cut two white felt bands with narrow black borders and run them around the hoodie and one pant leg; removable fabric tape holds for a party, but on a stretchy knit I'd add a few safety pins on the inside so the band doesn't pop off when the wearer bends. Put orange felt fins under the arms and make the right one noticeably smaller, since that little lucky fin is the detail fans look for. Large felt eyes and a soft fin along the hood's centre seam finish the head. Makeup can stay light: peach blush, a few tiny white dots and a clear gloss. A small blue bucket painted like water, or a plush anemone, gives the hands something to hold in photos.
2. DIY Dory Costume With Blue Dress

A bright blue T-shirt dress is the quickest Dory base I know, and it moves far better than a padded fish suit. Black felt markings go along the sides and a yellow panel near the hem suggests her tail; I cut the yellow slightly wider than feels right, because thin yellow disappears under evening light. Yellow tights or knee socks with blue sneakers carry the colour down to the feet. Put the craft-foam eyes and a small fin on a blue headband so the face stays clear for talking and eating. A ponytail is easiest, though a short blue wig makes her read sooner. Blue liner with a wash of yellow shadow and a little highlighter keeps the makeup cheerful. Tuck a paper memory note inside a shell-covered crossbody bag; it's the prop people ask about all night.
3. Nemo And Dory Couple Costume

For two adults, this is the couple costume I'd recommend to anyone who hates being uncomfortable at a party. The Nemo partner wears an orange sweatshirt and matching pants with white-and-black felt stripes, orange fins and black sneakers. The Dory partner wears a royal-blue top and pants with black side panels, yellow cuffs and bright yellow shoes. Skip bulky masks and give both of you fish-eye headbands, so your faces stay visible in every photo. Orange and blue temporary hair colour pulls the pair together, though it can rub onto light collars, so wear the darker top under it. A little shimmer around the eyes and a shared cardboard wave or soft coral prop finish the scene, and you can still walk, dance and hand out candy all evening.
4. Nemo And Dory Best Friend Costume

Best friends rarely want to sew, and this version doesn't ask you to. One friend goes as Nemo in an orange T-shirt, orange jeans, white striped suspenders and black canvas shoes. The other is Dory in a blue sweatshirt, black leggings, yellow socks and blue sneakers. Pin the lightweight felt fins from the inside of the shirt so the pin heads don't show, or use removable adhesive on fabric you'd hate to puncture. High ponytails with orange or blue ribbon extensions and matching fish-eye clips keep the hair part of the costume. A little coloured liner and a few scale marks near the temples are enough. Shell bracelets, mini bubble wands and ocean-blue treat bags round it off without adding anything you'll want to take off by nine o'clock.
5. Kids Nemo And Dory Costume

Kids give up on costumes that scratch, so I build this pair from soft layers they'd happily wear to school anyway. One child wears an orange long-sleeve shirt, orange sweatpants, white-and-black fabric bands and cushioned sneakers as Nemo. The other wears a blue tunic, blue leggings, black felt patches, yellow socks and secure athletic shoes as Dory. Stuffed felt fins bend when a child sits or tumbles, where cardboard creases on the first hug and then pokes. Beanies with fabric eyes and small top fins add warmth and character at once. If you use face paint, choose a child-safe one and test a dot on the inner arm the day before, then keep it to a few dots on each cheek. Shell buckets and reflective wristbands help you spot your two fish in a crowd of trick-or-treaters.
6. Toddler Nemo And Dory Costume

With toddlers I plan for nappy changes and naps first, and the character second. Orange and blue cotton rompers or two-piece pajama sets are ideal, since they open easily and the colour is already there. On the Nemo outfit, add soft white-and-black stripes and two fins, one small and one larger. The Dory outfit gets yellow ankle cuffs, black side markings and rounded blue fins. Keep fabric glue to removable panels and well away from snaps and buttons, because glue stiffens the fabric right where it has to flex. Soft fish hats should have embroidered or firmly sewn eyes; anything glued on will end up in a mouth. Washable cheek colour is plenty. Add nonslip shoes and give the little tote bags to the grown-up, who'll end up carrying them anyway.
7. Baby Nemo And Dory Costume

For babies, I keep every decoration flat and sewn, because a baby spends the evening being held, rocked and laid down. Nemo is an orange footed romper with white bands edged in black fabric, plus a small padded fin on each side placed where it won't press into the back when the baby lies down or crawls. Dory is a blue romper with smooth black patches, yellow feet and flexible side fins. Stretchy cotton caps with flat fabric eyes and tiny top fins replace wigs and rigid headpieces. There's no need for makeup at all; the orange and blue do the job. If you want more scene, drape the stroller in removable blue fabric with felt bubbles and soft coral, which makes a sweet miniature ocean for family photos.
8. Sibling Nemo And Dory Costume

Siblings usually want to match and stand out at the same time, and this pair lets them do both. The Nemo sibling might wear orange overalls over a striped white-and-black shirt with an orange cap topped by felt eyes and fins. The Dory sibling can wear a blue skater dress or blue overalls with a black top, yellow leggings and a fish headband. Orange high-tops for one and yellow rain boots for the other keep the feet bright and kid-friendly. Ask each child before adding washable face glitter or painted cheek scales; one may love it and the other may refuse, and that's fine. Matching shell necklaces with separate ocean-blue candy buckets prevent the usual argument over whose sweets are whose. On a cold night, slide thermal shirts underneath; the orange and blue still show on top.
9. Parent And Child Nemo And Dory Costume

I always let the child choose first with this one, then build the adult around whichever fish is left. A child's Nemo can be an orange sweatshirt with striped felt panels, orange joggers, a fin headband and sneakers. The adult's Dory might be a blue sweater dress with black leggings, yellow ankle boots and a blue-and-yellow tail cape; if the child wants Dory, simply swap the roles. Keep both faces uncovered and share a little blue shimmer around the eyes so you look like a set. The parent carries a coral-shaped tote with water, snacks and spare layers, which is honestly the most useful prop of the night. It's an easy pair to walk a full trick-or-treat route in, and the photos come out warm and obviously connected.
10. Plus Size Nemo And Dory Costume

Restrictive one-piece fish suits rarely fit well past a narrow size range, so for plus size Nemo or Dory I start with garments that already fit and simply add the character. Nemo can be an orange swing dress or roomy sweatshirt with orange leggings, striped felt panels and cushioned black shoes. Dory can be a blue tunic or relaxed jumpsuit with black side accents, yellow cuffs and supportive yellow sneakers. Place the lightweight fins along the upper arms or shoulders, where they add shape and stay out of the way when you sit. A headband, a few coloured hair clips and soft ocean-toned makeup are all the head needs. Breathable stretch fabric and removable costume tape keep everything flexible. A crossbody shell bag leaves your hands free for drinks, candy or a phone.
11. Last-Minute Nemo And Dory Costume

Short on time? Colour blocking does most of the work, and nothing here needs a needle. The Nemo wearer needs an orange shirt and pants, white tape or felt strips with narrow black borders, and black shoes. The Dory wearer combines a blue shirt with black pants, yellow socks and blue sneakers. Cut quick fins from craft felt and attach them with removable clothing tape. Paper plates or cardstock make large fish eyes that clip onto plain headbands, though they bend in damp air, so keep them indoors if the night turns wet. Orange or blue liner and a few shimmer dots stand in for detailed face paint. Tote bags with paper bubbles finish the pair, and because the two colours are so distinct, people still get it at a glance.
12. No-Sew Nemo And Dory Costume

My favourite trick for a no-sew pair is to keep every character piece off the clothes themselves. Start with an orange tracksuit for Nemo and a blue tracksuit for Dory. Add white-and-black bands to the orange set and black shapes with yellow tail accents to the blue. Cut the side fins from stiff felt and slide them onto elastic armbands instead of sticking them down; they sit straighter and you can adjust them in seconds. Peel-and-stick eyes and small foam fins go on baseball caps. Orange sneakers for Nemo and yellow for Dory keep the feet in the story. Cheek scales drawn with a cosmetic pencil through a scrap of mesh look surprisingly neat. When it's over, peel everything off and the tracksuits go straight back into normal rotation.
13. Nemo And Dory Tutu Costume

Tulle gives this pair bounce, but it also snags on everything, so I keep the tutus shorter than knee length for anyone walking a long route. Nemo pairs an orange top with a layered orange, white and black tutu, orange tights, and black ballet flats or sneakers. Dory wears a royal-blue top with a blue, black and yellow tutu, yellow tights and blue shoes. Flexible fins sit on the shirt sleeves and the fish eyes go on comfortable headbands. A bun or high ponytail tied with orange or blue ribbon keeps the hair from hiding the headband. Shimmer shadow, rosy cheeks and a few hand-drawn scales near the temples suit the playful skirt. Small shell purses hold the essentials. I'd point anyone heading to a dance recital, a school party or a costume night toward this one.
14. Nemo And Dory Onesie Costume

Onesies are the easiest full-body option here, and the hood solves the hair question entirely. Choose an orange hooded onesie for Nemo with white-and-black bands, soft fins and large eyes on the hood. Dory's onesie should be royal blue with black side patches, yellow cuffs, a yellow tail panel and rounded fins. Fleece onesies get hot fast indoors, so wear a thin shirt underneath and you can unzip to the waist when the room warms up. Tuck natural hair under the hood and skip the wig. A touch of blue or orange shimmer on the cheeks is enough makeup. Slippers suit an indoor party, but switch to proper sneakers for anything outside, and share a bubble wand as your one prop.
15. Glam Nemo And Dory Costume

Sequins change the mood completely, and this glam pair still holds onto the character colours. Nemo can be an orange sequin dress with white-and-black waist bands, sheer orange tights and black ankle boots. Dory can be a blue sequin jumpsuit with black panels, yellow cuffs, and metallic yellow heels or flats. Shoulder fins cut from glittered craft foam should stay light and rounded; heavy foam drags a sequin garment off the shoulder within the hour. Style the hair in sleek waves with orange or blue extensions and jewelled fish-eye clips. Luminous base, graphic coloured liner and iridescent scales along the temples suit the shine. Be warned that loose glitter travels onto everyone you hug. Shell-shaped clutches and a few sparkly bubble accessories finish it for an adult party that leans dressy.
16. Casual Nemo And Dory Costume

Not everyone wants to look like a fish all day, and this casual pair hints at the characters with clothes you'd actually wear again. For Nemo, an orange sweater, white jeans with black striped details, orange sneakers and a small fin cap. For Dory, a blue denim jacket over a black top, yellow pants, blue sneakers and a fish-eye headband. One removable felt fin on each jacket sleeve or sweater side is what turns ordinary clothing into a costume. Keep your usual hairstyle and add colourful clips or a streak of temporary hair chalk, which brushes out at the end of the night. Soft orange and blue eye makeup ties the two together. Canvas totes painted with bubbles and coral suit a relaxed office, a campus event or a low-key gathering.
17. Warm Weather Nemo And Dory Costume

In a hot climate, the costume has to breathe or it comes off by the second street. Nemo pairs an orange tank top with orange shorts, white-and-black fabric bands, breathable orange sneakers and a visor carrying the fish eyes. Dory wears a loose blue T-shirt with blue shorts, black side patches, yellow sandals and a light fin headband. Felt fins that sit close to the body won't trap heat the way large foam pieces do. Braids or ponytails with orange and blue ribbon keep hair off the neck. Waterproof liner and only a little shimmer hold up better in humidity, since cream products slide once you start to sweat. Shell-shaped crossbody bags keep both hands free and mean nobody has to carry a bulky prop through the heat.
18. Cold Weather Nemo And Dory Costume

On a cold night, the outerwear becomes the costume, so I build the character onto the coat rather than hiding it underneath. Nemo's look starts with an orange puffer jacket, orange fleece pants, white-and-black fabric bands, insulated boots and an orange knit hat with soft eyes and fins. Dory's uses a blue puffer coat, black snow pants, yellow boot cuffs, blue winter boots and a matching fish beanie. Strap the padded side fins onto the outerwear with removable bands; tape and hot glue both let go in cold air. A long scarf can trail like a tail and keep a neck warm at the same time. Keep makeup to weather-resistant liner and a little cheek colour. Reflective bubble stickers on sleeves and treat bags make a long, dark trick-or-treat route safer.
19. Nemo Dory And Marlin Family Costume

Adding Marlin turns the duo into a family of three that tells the whole story. The child goes as Nemo in an orange hoodie, striped joggers, orange sneakers and a soft fin hat. One adult becomes Marlin in a darker orange sweater and orange pants with wider white-and-black bands and a slightly larger tail; the deeper orange is what separates father from son at a glance. The second adult wears Dory's blue tunic, black leggings, yellow shoes, rounded fins and a blue fish headband. Subtle scale makeup and matching shell bracelets link all three. Decorate a stroller or wagon as a coral reef with blue fabric and flexible felt plants. Every piece here adjusts easily for different ages, sizes, mobility needs and weather.
20. Nemo Dory And Hank Group Costume

Hank is the fun addition for three friends, and the trick is the tentacles. Nemo wears orange with white-and-black bands, side fins and orange sneakers. Dory wears royal blue with black markings, yellow accents and rounded fins. Hank starts with a rust-red sweatshirt and pants, then seven stuffed fabric tentacles on a lightweight belt, red shoes and a beanie with big eyes. Seven is right for him, so count them. I keep each tentacle short enough to clear the knee, because long stuffed tubes tangle around ankles on stairs. Orange, blue and reddish makeup around the eyes with a gentle shimmer gives all three a watery finish. Visitor badges, shell bags or a cardboard aquarium sign add a wink, and the three strong colours look great in group photos.
21. Nemo Dory And Crush Group Costume

Crush brings a third colour, green, and a shell that changes the whole silhouette of the group. Build Nemo and Dory with their usual orange-and-white and blue-and-yellow palettes, soft fins, fish-eye headbands, matching makeup and sneakers. For Crush, start with a green hoodie and brown joggers. A rounded brown shell panel goes on the back; make it from padded fabric rather than a stiff board so it doesn't knock into people when he turns. Green felt flippers along the arms, a turtle-eye cap and green athletic shoes finish him. A little light green face paint on the cheeks suggests the sea turtle without covering the whole face. Shell necklaces and blue bubble wands link the trio. All that sweatwear holds up through a parade or a long night outside.
22. Nemo Dory And Destiny Group Costume

Destiny's size is what makes this trio fun to look at: one small orange fish, one blue fish and one big whale shark. Keep Nemo compact and bright with an orange sweatshirt, striped pants, side fins and orange sneakers. Dress Dory in a blue tunic, black leggings, yellow boots, rounded fins, and a blue wig or headband. For Destiny, a loose blue-gray dress or sweatshirt set covered in white felt dots does the job; I cut the dots in a few sizes because identical circles look like polka-dot fabric rather than a whale shark. Add broad side fins, a wide padded tail, blue-gray shoes and a headband with friendly eyes. Shimmery blue makeup ties the three together. Destiny can carry lightweight cardboard glasses as a nod to her poor eyesight, while the fish hold shell bags. Keep every attachment soft so the group can move safely.
23. Nemo Dory And Bruce Group Costume

Bruce has to look friendly or the joke falls flat, so I keep the shark soft and cartoonish. Nemo wears orange layers with white-and-black stripes and Dory wears blue with yellow and black accents. Bruce begins with a gray hoodie and matching sweatpants. Attach a white belly panel, a soft triangular back fin, flexible side fins and a stuffed gray tail. Rounded white felt teeth along the hood edge, under large cartoon eyes, read as a grin rather than a threat; pointed teeth tip it into scary very quickly. Gray sneakers finish him. Silver shadow and pale blue cheek highlights suit him better than dramatic shark makeup. Bubble props or seaweed garlands tie the trio together for friends, siblings or a small family.
24. Aquarium Tank Nemo And Dory Costume

This is the most structured idea on the list: Nemo and Dory each wear their own little aquarium. Both start with simple orange and blue outfits, the right stripes, yellow accents, fins, fish-eye headbands, makeup and comfortable sneakers. Build the tank frames from foam board or covered cardboard and leave the top, bottom and sides open so air moves and legs can walk. Paint the borders blue and add flexible coral, bubbles and green fabric seaweed. Hang each frame from wide shoulder straps; narrow straps cut in after an hour. Keep anything rigid away from the face and knees, and know that cardboard softens quickly in rain. Give Nemo's tank a small anemone corner and Dory's a few shells. It photographs well and needs no complicated sewing.
25. Sea Anemone Nemo And Dory Costume

A soft anemone skirt gives the duo texture without the bulk of the tank frame. Both people wear full Nemo and Dory outfits first: colour-blocked tops and bottoms, flexible fins, matching headpieces, simple scale makeup and secure shoes. Then tie strips of pink, purple and red tulle onto elastic belts to make coral tentacles around each waist. Keep the strips above the knee; longer ones wrap round the legs with every step. Nemo's belt can carry denser coral, since he lives in the anemone, while Dory's has scattered shells and blue ribbons as if she's swimming past. Tuck hair under the headbands or add short orange and blue wigs. Small ocean-blue bags and bubble wands finish it, and the whole thing stays soft and family-friendly.
26. School-Friendly Nemo And Dory Costume

School rules usually ban masks, props that look like weapons and anything that stops a child sitting at a desk, so this pair is built to pass those checks. Nemo wears an orange polo or sweatshirt with removable white-and-black bands, orange pants, flat shoes and a small fin headband. Dory wears a blue tunic over black leggings, yellow socks, blue sneakers and a rounded eye headband. Keep the side fins short and close to the body; long ones catch on chair backs and backpack straps all day. Coloured liner and a few tiny cheek scales are enough makeup, if the school allows it at all. Swap big props for shell pins, bubble bracelets or a themed tote. Because everything layers over ordinary clothes, it comes off easily after the parade or performance.
27. Work-Friendly Nemo And Dory Costume

At work, I'd suggest the characters through tailoring and keep the obvious costume pieces small. Nemo pairs an orange blazer with a white blouse, black trousers, orange loafers and striped orange-and-white accessories, plus a small clownfish fin pin and a slim orange headband. Dory wears a royal-blue blazer and trousers with a black top, yellow flats and a yellow belt, adding a small blue fin clip and shell earrings. That yellow belt is the detail that makes her readable, so don't skip it. Neat hair and restrained orange or blue liner keep things professional. Structured bags with removable bubble charms finish both. It's a sensible choice for an office that allows costumes but still has meetings on the calendar.
28. Maternity Nemo And Dory Costume

For a pregnant wearer, nothing should press on the waist, and the bump can actually become part of the design. For Nemo, choose a stretchy orange maternity dress and place the white-and-black bands above and below the bump rather than across it, so they don't ride up. Add soft side fins, orange leggings, supportive black sneakers and a light fish-eye headband. For Dory, a flowing blue maternity tunic with black side panels, yellow cuffs, black leggings and cushioned blue shoes. Fins near the shoulders are more comfortable than anything at the stomach. Natural hair with blue or orange clips and gentle shimmer makeup keep it easy. A shell crossbody bag holds essentials, and a light cardigan in the character's colour adds warmth without covering the look.
29. Nemo And Dory Pet Costume

Pets only tolerate costumes that feel like nothing, so a lightweight vest is the only form I'd use here. Choose an orange harness-style vest with white-and-black bands for Nemo, or a blue vest with black markings and yellow trim for Dory. Attach short, flexible fins that can't reach the face or legs. Leave out wigs, makeup, shoes, masks and anything that dangles. If your pet happily wears headgear, use a soft cap with flat eyes for a quick supervised photo, then take it off. Two fingers should slide under every strap, and if the animal freezes, scratches or tucks its tail, the costume comes off. You can wear the matching fish yourself, with coloured clothing, a headband, a little makeup and sneakers, for a pet-and-owner pair.
30. Light-Up Nemo And Dory Costume

Lights do two jobs on this pair: they look like glowing water and they make you visible to drivers after dark. Build both looks from orange and blue sweatshirts, matching pants, felt markings, flexible fins, decorated headbands and secure sneakers. Run cool-touch LED wire around Nemo's white bands and along the yellow edges of Dory's fins, stitching it down every few inches so it doesn't sag. Battery packs go in zipped pockets, and no wire should hang anywhere near the feet. Reflective bubbles on sleeves and treat bags add extra shine. Orange and blue hair extensions, iridescent eye makeup and shell bracelets finish the pair. Test every strand before you leave home, and clip the electrics on so they come off before the clothes go in the wash.
Droopy Fins, Slipping Eyes and Rain
Most fish costumes look fine at the front door and tired an hour later. These are the fixes I'd pack in a pocket, because they save the evening more often than any extra detail would.
When the fins start flopping
Single-layer felt fins droop once they warm up against the body. Cut two layers and sandwich a piece of stiff interfacing or thin craft foam between them, then stitch round the edge. Foam fins hold their shape but crack at a sharp fold, so give them a gentle curve instead of a crease.
Headband eyes that slide forward
Big foam eyes make a headband top-heavy, and it creeps forward until it sits on the eyebrows. Wrap the band in a strip of felt or ribbon so it grips the hair, and set the eyes slightly behind the top of the band rather than in front. Two bobby pins crossed over each side hold it steady on finer hair.
If it rains
Felt survives a drizzle, but paper-plate eyes, cardboard tanks and paper bubbles soften and sag. Have a fabric version of the eyes ready, or wear a clear rain poncho that leaves the colours showing. Damp felt can transfer a little dye onto pale clothing, so let pieces dry flat overnight. Kept in a shallow box, the fins and bands are ready for the same hoodie to be Nemo again next year.
Two Colors, One Small Fin, and a Night Out
Nemo and Dory stretch further than most character pairs: solo looks, couples, best friends, kids, families, groups, pets and expectant parents all have a version above. In every case I'd start with the orange or blue clothing, then add the markings, flexible fins, a headpiece, light makeup and shoes you can actually walk in. Felt, fabric tape, hoodies, dresses and tracksuits keep most versions affordable and easy for beginners. Put visibility, movement, weather layers and secure attachments ahead of extra detail, especially for children and pets. A simple closet version and a lit-up aquarium both land, as long as the right fin is the small one.
