Toothless is a gift to anyone who sews, because the whole character is one color and a handful of shapes. Matte black body, big green eyes, ear flaps and small fins on the head, broad wings, a long tail and that one red replacement fin: get those right and people will shout his name before you reach the door. That means you can make him at almost any skill level. A black hoodie with felt pieces is an afternoon project; folding wings, lights or a saddle harness take a weekend or more. Below you'll find soft kids' versions, humanized adult looks, couple and family pairings and even a dog. Whatever you choose, plan it around seeing clearly, sitting down and getting through doors.
Sewing a Dragon Tail That Doesn't Droop or Drag
Almost every costume below has a tail, and it's the part that fails most often. A tail sewn straight onto pants pulls the waistband down. One stuffed too firmly swings into people and knocks things off tables. One stuffed too lightly hangs flat and drags behind you. This is how I make one that behaves.
- Cut two long tapered pieces of black fleece or knit, about as long as the wearer's leg and wide enough at the top to wrap around a fist. Sew them right sides together, leaving the wide end open, and turn it out.
- Stuff the tip and middle lightly with polyfill, then stuff the top third a little firmer. A stiff base and a soft tip lets the tail lift slightly and then fall naturally.
- For a tail that curves, slip a strip of plastic boning or a length of soft wire wrapped in tape into the top section before stuffing. Never put wire anywhere near the tip, where a child can grab and bend it.
- Stitch a wide loop of webbing or elastic onto the open end and thread a separate belt through it. The belt carries the weight, so the costume underneath stays put.
- Make each fin from two layers of felt with fusible interfacing in between, then stitch it to the tip. The red fin is the detail people look for, so give it clean edges.
Measure the finished length with the wearer standing in their shoes. The tip should stop a few inches above the ground; anything lower gets stepped on by whoever is behind you.
1. DIY Hoodie Toothless Costume
A black hoodie is the base I'd hand to a first-time costume maker. Wear it with black joggers or leggings so the body reads as one dragon shape rather than a top and bottoms. Cut green eyes, rounded ear flaps and small head fins from felt and stitch them to the hood; a stiff felt or a layer of fusible interfacing on the back keeps the ears from flopping over by mid-evening. Black felt wings can run from the sleeve seams to the back. Pin or sew a lightly stuffed tail to the waistband and add the red fin at the tip. A little green eye makeup or black paint around the eyes, black gloves and sneakers, and you have a warm costume that walks all night.
2. Fleece Jumpsuit Toothless Costume
Black fleece gives you the soft, rounded Toothless shape, and it's warm enough for a chilly October street. Start with a plain black jumpsuit or one-piece pajama suit. For the fins down the spine, I sew small fleece triangles with a little stuffing and stitch them in a row from the hood to the lower back, stopping above the seat so sitting is still comfortable. Large green felt eyes go above the forehead with four soft head flaps. Fabric wings under the arms, and a long stuffed tail with one black fin and one red fin with a simple white mark. Black mittens and fleece-covered slip-ons. Leave the face bare or add a little gray shading on the cheeks.
3. Toothless Costume With Folding Wings
Folding wings are the upgrade that gets a reaction, because they move when you do. Wear a fitted black long-sleeve shirt, black pants and light boots, then build each wing from black fabric stretched over flexible rods such as fiberglass tent poles or thin plastic tubing, and mount them on a backpack-style harness. Wrist loops let the wings open when the arms lift and fold flat when they drop. A black foam headpiece with green mesh-covered eye openings, ear flaps and short fins sits on top, and the padded tail with its red fin hangs below the harness. Matte black makeup on any visible skin. Practice in a hallway first; the wingspan is wider than you'll guess.
4. Light-Up Toothless Costume
Green light behind the eyes is a striking touch at an evening party. Build the base from a black bodysuit or matching black athletic separates. Put small battery-powered green LEDs behind translucent eye shapes on a foam or fabric hood, with a layer of thin white fabric in between to spread the light so it glows instead of showing two bright dots. Keep the battery pack in an inside pocket you can reach. Black wings with faint reflective scale marks, and a stuffed tail with black side fins and one red panel. Green liner, black gloves and nonslip boots. Use cool-running lights only, tape every loose wire flat, and keep the electrics away from rain.
5. Glam Toothless Dress Costume
A black dress turns Toothless into a dressy humanized look while keeping the dragon parts that matter. Pick a fit-and-flare dress you can sit and dance in, ideally with some texture such as sequins, a crinkle knit or a faint scale print. Sheer black wing panels run from the wrists to the waist and spread when the arms lift. A headband with four black fins and two green eye details. Attach the slim tail to a separate belt under or over the dress; hooked straight onto the fabric, it pulls the skirt out of shape. Green shimmer around the eyes, soft black liner and a neutral lip. Black tights, low ankle boots, claw-tip gloves and a red fin finish it.
6. Toothless Tutu Costume
The tutu version is made for kids who love to spin. A black long-sleeve leotard, a layered black tulle skirt and opaque leggings underneath. Soft fabric wings across the back, ending above the wrists so they don't trail over the hands. A black headband or snug hood holds the ears, small fins and oversized green eyes. Attach a light stuffed tail under the tutu with one bright red fin. I'd use green face shimmer around the eyes instead of a mask, since masks block side vision. Ballet flats, sneakers or flexible boots, and soft claw gloves that pull off easily for snacks and classroom crafts. Multiple tulle layers in black can look heavy, so mix in one charcoal layer for depth.
7. Toothless Bodysuit Costume
A fitted black bodysuit gives adults the sleek, aerodynamic Toothless, and it's also the least forgiving base on the list. Layer shorts, a wrap skirt or fitted pants on top if you want more coverage. Scale texture can come from fabric paint stenciled in small overlapping arcs, or pieces of flexible faux leather on the shoulders and outer legs. Never hang wings from a bodysuit itself; the stretch fabric pulls and gapes, so put them on a separate harness. A sculpted foam headband with small fins, ear flaps and green eye accents. A long tapered tail on a sturdy belt. Green graphic liner and soft black contour suggest the face. Fitted gloves and flat black boots.
8. Plus Size Toothless Costume
For a plus-size Toothless, I build around the clothes that already fit well rather than a costume-bag jumpsuit. A black tunic, a stretch jumpsuit or a matching top and pants with plenty of room to move. Carry the tail on a wide harness or supportive belt so its weight sits on the hips instead of dragging at the fabric. Cape-style wings that fall from the shoulders give a dramatic outline without anything tight under the arms. A padded hood with green eyes, ear flaps and soft fins does most of the recognition work. Add scale texture with removable felt patches or fabric paint. Cushioned black boots, light gloves, green shadow with winged liner and a soft pearly highlight.
9. Maternity Toothless Costume
Toothless suits pregnancy well, since nothing about him needs a fitted waist. A black maternity dress or long tunic with soft leggings and cushioned slip-on shoes. Cape wings that fasten at the shoulders, never across the middle. Hang the tail from a loose fabric belt worn wherever it's comfortable, above or below the bump, and keep it light; a tail tugging at the back gets tiring fast. A soft black beanie with green felt eyes, ear flaps and small fins. Green eye makeup and a touch of silver highlight. If you'd like more detail, a removable oval scale panel on the front of the dress adds texture without pressure.
10. Men’s Toothless Costume
A men's Toothless can be built almost entirely from athletic wear, which keeps it comfortable for a long night. A black compression shirt or sweatshirt, tapered black pants and sturdy black boots. Textured fabric or painted craft foam scale panels across the chest and shoulders. Large wings go on a backpack harness so the weight sits across the torso instead of pulling on the neck. A fitted hood with green eyes, four head fins and a broad, rounded snout. A padded tail on a utility belt with the red fin. Black gloves with short foam claws. Keep makeup to black shading around the eyes and a narrow green line on the lids.
11. Humanized Toothless Costume
A humanized Toothless reads the dragon through clothes instead of a creature suit, and it's the one I'd suggest for an adult or teen who doesn't want their face covered. A black mock-neck top, fitted cargo pants, a textured vest and lace-up boots. A short wing-shaped cape or structured shoulder wings. A black headband with small ear flaps and fins, with the wearer's own hair showing. Bright green eye makeup stands in for his eyes, and a red belt panel nods to the repaired tail fin. Fingerless gloves with small claw tips and a detachable tapered tail. Keep the shapes rounded; he's a friendly dragon, and sharp angles make the look feel like a different character.
12. Kids Toothless Costume
For a busy child, the costume has to survive running, climbing and other kids grabbing the tail. A black sweatshirt, matching sweatpants and supportive sneakers. Green felt eyes, small rounded ears and flexible fins on the hood, with no stiff edges near the face. Keep the wings short so they clear doorways and other children. A lightly stuffed tail on an elastic waistband, with a black fin on one side and a red one on the other; I stitch it with a doubled seam at the base, because that's where kids yank. Removable black mittens with fabric claws. Green around the eyes and a few gray scale marks on the cheeks, and reflective trim on the wing edges.
13. Toddler Toothless Costume
Toddlers do best with as little extra as possible. A soft black hooded romper or a sweatshirt-and-jogger set. Sew the felt eyes and flat head fins straight onto the hood so there's no headpiece to lose. Small fabric wings stitched across the shoulders, short and soft enough to sit comfortably under a carrier strap, but take any bulky pieces off for the car seat. Pad the tail lightly and attach it high enough that it never drags. Make the red fin from soft felt rather than foam. Black socks and nonslip shoes. Skip face coverings, and if you use paint, only a little green near the eyes. Then sit them on the floor in it once to see if anything pokes.
14. Baby Toothless Costume
A baby Toothless is mostly about pictures, so softness comes first. A black footed onesie with snaps or a zip. Flat green felt eyes and tiny fabric ears on the hood, placed so they never fall over the baby's eyes. Wings stitched flat to the back like appliqués rather than sticking out. A short stuffed tail with one black and one red fin, attached where it won't get in the way of diaper changes. No face paint, masks, hard foam, loose trims or claws. A soft black cap can stand in for the hood. Lay the baby on a bright padded blanket so the black reads in photos, and take the costume off for sleep, feeds and car rides.
15. Teen Toothless Costume
Teens usually want Toothless without looking like they borrowed a little sibling's costume. A cropped or regular black hoodie, cargo pants, high-tops and fingerless gloves. Detachable wings in black ripstop nylon look sporty and pack flat into a backpack. Green eyes, short ears and flexible fins on the hood, or just a dragon headband. A slim tail on a belt is easy to manage at school or a party. The red fin works as the one bold accent. Green liner, black mascara and a few small scale marks near the temples. Ripstop takes iridescent fabric paint well, so a little shine on the wing edges adds dimension without breaking the all-black look.
16. Last-Minute Toothless Costume
With an evening's notice, the closet and a pack of felt will do it. A black hoodie, leggings or sweatpants, gloves and sneakers. Cut wings, ears, head fins, green eyes and a tail from felt or sturdy poster board. Attach the face pieces to the hood with removable fabric tape or safety pins fastened on the outside, away from the skin. Loose elastic loops hold the wings at the wrists, and the tail attaches to a belt. The red fin is what makes it Toothless rather than a generic black dragon, so don't skip it, even if it's paper. Green eyeshadow and black liner for the face, and no sewing needed.
17. No-Sew Toothless Costume
No-sew is a good way into costume making for anyone without a machine, though glue has habits worth knowing. Start with black sweatpants, a black sweatshirt and plain black shoes. Cut two wings and a tapered tail from thick felt. Glue the tail edges with fabric glue, leave an opening, add light stuffing, then close it. Fabric glue needs a full day to cure, and felt glued in a rush peels apart at the first tug. Use adhesive hook-and-loop strips to fix the tail and wings to a wide belt or simple harness. Make the hood details from craft foam: green eyes, ear flaps, nostrils and flexible fins. Black gloves with foam claws and green cream makeup around the eyes.
18. Cardboard Toothless Costume
Cardboard gives Toothless structure on a tiny budget, and it suits a kid who wants wings that hold their shape. Wear an all-black base with comfortable shoes and gloves. Cut matching wings from corrugated cardboard by tracing one onto the other, round every corner and paint both sides matte black. Wide fabric shoulder straps let the wings sit like a backpack. A cardboard headpiece can have a broad snout, big green eyes and rounded fins, but leave it open around the face for sight and air. Roll the tail from black poster board, or wrap fabric around light paper filling, and add a red fin. Paint gentle gray scales on the wings and tape every cut edge. Cardboard goes soft in rain, so keep a bag handy.
19. Warm Weather Toothless Costume
In a warm climate, a full black fleece suit is miserable within the hour, and black absorbs sun. Go with a breathable black T-shirt, athletic or cycling shorts and light sneakers. Swap the hood for a slim headband with soft ears, small fins and green eyes. Sheer black mesh wings from wrist to waist let air through. Leave the tail unstuffed so it adds no heat or weight, and keep the red fin. Fingerless gloves hint at claws and keep hands cooler. Waterproof green liner holds up to sweat better than cream shadow. Bring water and make every piece easy to take off.
20. Cold Weather Toothless Costume
For a cold outdoor night, the trick is to make Toothless fit over real layers rather than under them. A black thermal shirt, fleece-lined leggings or pants, and an insulated black coat. Decorate the coat's hood with bright green eyes, soft ears and padded fins, using safety pins or a few loose stitches so the coat goes back to normal later. Large fabric wings across the back, clear of the zip. A stuffed tail on a belt worn over the coat, with black and red fins. Black winter gloves already look the part and can take removable felt claws. Waterproof boots with grip. Keep face paint light, and add reflective tape along the wing edges for walking after dark.
21. Toothless Pajama Costume
Pajamas make a cozy Toothless for movie nights, home parties or an easy trick-or-treat. Choose a black long-sleeve top and jogger-style pajama pants with cuffed ankles, since loose wide hems catch under shoes. A soft dragon hood or black beanie with green eyes, ear flaps and short fins. A fleece wing cape that fastens at the neck with a breakaway closure, such as a small hook-and-loop tab, so it pulls free if it snags. A plush tail with the red fin on a fabric belt. Black slipper boots indoors, supportive sneakers outside. Green eye makeup and soft black gloves. Fleece doesn't fray, so the wing cape needs no hemming at all.
22. Toothless Costume With Red Tail Fin
This is the version for anyone who cares most about getting the tail right. Start with a matte black jumpsuit, black gloves and close-fitting boots. Sew wings with curved upper edges and a few lines of scale stitching. Make a long padded tail that narrows toward the floor without touching it; a strip of plastic boning or a light wire inside the top third holds a gentle curve. One side carries a natural black fin, the other the bold red replacement fin with a simple pale emblem. A fitted black hood with green eyes, nostrils, ear flaps and small fins. Green liner and charcoal shading if the face shows. Keeping everything else strictly black is what makes the red fin pop.
23. Alpha Toothless Costume
Alpha Toothless is the glowing version, with pale blue markings along his head, spine and wings, and it's a more ambitious build. Start with a black bodysuit or jumpsuit with matching gloves and boots. Paint or appliqué the blue markings along the forehead, spine, wings and tail; reflective fabric or cool-running blue LEDs give a glow without paint smearing onto everything you touch. Broad articulated wings and a supportive tail harness. A headpiece with green eyes, ear flaps, small fins and blue accents. Blend blue and black around the eyes and add fine light lines on the temples. Keep the lighting light in weight, and add the red fin if you want strangers to name him at once.
24. Mascot Toothless Costume
A mascot-style Toothless is round, friendly and very warm to wear. Use a padded black body suit with a roomy torso, attached shoe covers and oversized claw mitts. Shape a large, light head from upholstery foam, then cover it in black fleece or minky, which stretches over curves without wrinkling; hide mesh openings where you'll look out and where air can get in. Huge green eyes, a broad nose, small rounded ears and a cheerful face. Wide fabric wings and a thick padded tail with one red fin. Keep the feet flat and nonslip, never on platforms. A cooling vest and regular breaks matter more than any detail. Practice walking, turning and sitting before going near guests or children.
25. Toothless And Hiccup Couple Costume
Toothless and Hiccup is the obvious couple costume, and the dragon-and-rider pairing makes both halves easier to read. The Toothless wearer goes in a black hooded jumpsuit with green eyes, fabric wings, claw gloves, black boots and the red-finned tail. Hiccup wears a green tunic, fitted brown pants, a textured brown vest, wrist guards and tall brown boots, plus tousled brown hair and a small crossbody pouch. The link between them is the harness: put matching brown straps around the dragon's shoulders and waist so the two costumes share a material. Keep everything soft and light. For photos, open the wings and have Hiccup stand beside the tail fin, since he built it.
26. Toothless And Light Fury Couple Costume
Toothless and the Light Fury give you a black-and-white couple that works on contrast. Toothless wears a black jumpsuit with green eyes, ear flaps, broad wings, black gloves and the red fin. The Light Fury wears a white or pearly fitted outfit, soft white wings, a tapered tail, blue eye accents and smooth rounded head fins; she doesn't have Toothless's spiky look, so keep her shapes sleeker. Add a little iridescent scale detail to the white costume and matte texture to the black one. White fabric shows every smudge, so pre-treat it with a fabric protector spray if you have one. Matching sneakers or ankle boots, green around one pair of eyes and pale blue around the other.
27. Toothless Family Costume
A Toothless family works best as dragons and riders, so each person gets a costume they like. One adult or child wears the main black dragon with green eyes, wings, gloves, boots and the red-finned tail. Others go as Viking riders in earth-tone tunics, faux-fur-trimmed vests, fitted pants, wrist cuffs and sturdy boots. A second dragon can be the white version with blue eye details, and a baby can wear a simple black or white winged romper. Repeat the same brown harness strapping across the group to connect everyone. Skip heavy helmets and masks for young kids. In photos, put the dragons in front so wings and tails stay visible.
28. Toothless Group Costume
A group of Toothlesses is funnier when nobody matches exactly. One person wears the classic black dragon with green eyes and the red-finned tail, another the Alpha version with blue markings, a third the glam dress with sheer wings, and another the hoodie-and-joggers take. Agree on the shared elements: a black base, visible wings, head fins, claw gloves, sensible shoes and some kind of tail. Then let textures and outlines differ. Green eye makeup on everyone pulls it together. One thing to check ahead of time: blacks vary a lot between fabrics, so compare them side by side in daylight, or the group photo will show five different shades. Put taller wings at the back.
29. Toothless Dog Costume
A Toothless dog costume should work around how the dog moves, not the other way around. Use a soft black vest or harness as the base instead of covering the whole body. Small flexible wings on the back and a short fabric tail near the rear of the vest, both well clear of the legs. Sew the red fin flat onto the tail. Add a loose hood with green eyes and soft ears only if your dog already accepts things on its head; otherwise put the eyes on the harness. Skip paw covers, since they change how a dog walks. Let your dog sniff each piece first, stay with them the whole time and take it all off the moment they seem unhappy.
30. Toothless Costume With Saddle Harness
A saddle harness is a fun detail because it's how Hiccup rides him: a saddle linked by a cable to the tail fin so the rider can steer it. Start with a black padded jumpsuit, claw gloves and flexible black boots. Add large textured wings, leaving room for a brown faux-leather harness to cross the chest and waist. The harness carries a light decorative saddle panel between the wings, and a cord running back to the tail fin sells the story. Attach the padded tail below it with both the black fin and the red replacement fin. A rounded black hood with green eyes, small ears, nostrils and soft fins. Use quick-release buckles, keep straps off the neck, and test it walking, sitting and lifting your arms.
Black Fleece, Lint and Getting Seen After Dark
An all-black costume has two problems that only show up on the night. First, black fleece and felt pick up every bit of lint, pet hair and glitter in the house, and it all shows in flash photos. I keep a lint roller in the bag and give the costume one last roll at the door. Washing fleece inside out on a cool cycle, with no towels in the same load, keeps it from pilling.
Second, a black dragon is very hard for drivers to see. Reflective tape or reflective trim along the wing edges and down the tail costs very little and disappears into the design in daylight. A small clip-on light on a child's treat bag helps too. If the costume has a face-covering headpiece, I'd still leave the eyes and the lower face open, since side vision matters far more crossing a dark street than at a party.
Do the Green Eyes on the Hood or on the Face?
Felt eyes on the hood are the easy answer for kids, because they stay put and need no makeup. For adults, green eyeshadow and a sharp liner give a more expressive Toothless, and you can do both. Put the hood eyes high enough that they sit above the forehead, not over the wearer's own eyes, so the costume reads from a distance and the wearer can still see the curb.
Black Base First, Red Fin Last
Every Toothless here starts the same way: a comfortable black base, then green eyes, rounded head fins, wings, claws and that red tail fin. A hoodie version is a beginner's afternoon; folding wings, lights, scale texture and a saddle harness are bigger builds for confident makers. Kids and pets need soft, light pieces that never block their sight or slow them down. Adults have room for glam, humanized, mascot, couple and group takes. Whichever you make, put it on and walk around the house in it before the night, then fix whatever pulls, droops or pokes.
