Yoshi is one of the friendliest costumes I know to sew, because he's mostly simple shapes on a soft base. The green dinosaur is the classic, but the games are full of red, blue, pink and yellow Yoshis too, so a group can each take a colour. What makes him read is a short list of parts: a white belly oval, big rounded eyes on the head, red spikes down the back, a red shell, a tail and orange shoes. You can sew those from fleece, cut them from felt or stick them onto clothes you already own. Below are thirty-five versions for adults, kids, couples, groups and even the dog, with notes on where each one tends to come apart.
Felt or Fleece for the Belly and Eyes?
Nearly every Yoshi below uses a white belly oval and two big eyes, and the material you pick decides how long they last. Craft felt is cheap and cuts cleanly, but it pills and stretches out of shape when it's stitched to a soft hoodie that bends all evening. Fleece has a little give, doesn't fray, and moves with the garment, so it's my choice for anything sewn on.
For the eyes, I cut two fleece ovals per eye, sew around the edge leaving a gap, stuff lightly with polyester fiberfill and close it up. Stuffed eyes hold their dome; flat felt eyes on a hood just look like patches. The black pupils can be felt, since they don't move much. If you're gluing instead of sewing, use a fabric glue that dries flexible. Hot glue sets hard, cracks when the hoodie bends and lets go in the wash.
1. Classic Green Yoshi Costume
For the most classic Yoshi, start with a green fleece jumpsuit, or a matching sweatshirt and joggers if you'd rather have two pieces. A big white felt oval goes over the stomach; fabric tape works for a no-sew version, but on fleece I'd add a few hand stitches at the edges, because tape lets go where the fabric stretches. Padded white eyes with black pupils sit on the hood, and soft red spikes run down the back. For the shell, a red cushion covered in fabric and edged in white felt looks right and weighs almost nothing. Orange sneakers or shoe covers, hair tucked under the hood, a light felt tail and a spotted egg finish him.
2. Easy DIY Yoshi Hoodie Costume
A plain green hoodie gets you most of the way there. Glue or hand-sew stuffed white felt eyes onto the hood with black pupils, then a row of red triangle spikes. Green sweatpants and a white fleece belly panel on the front make the body. My favourite trick here is using a small red backpack as the shell, since it holds your phone, keys and candy. Long hair goes in a low braid so the hood still fits. A few green face gems or a line of green liner keep the face fun, and orange sneakers, a detachable tail and a foam egg under one arm round it out.
3. Yoshi Onesie Costume
A ready-made onesie is the cosiest route for a cold night. Look for a green hooded suit that already has a white tummy, a tail, red spikes and eyes; if there's no shell, pin a light red-and-white felt circle between the shoulders. Fleece onesies get hot fast indoors, so I'd wear a thin shirt and shorts underneath rather than a full outfit. Two low braids keep hair tidy under the hood. A tinted balm and a sweep of green shadow are all the makeup it needs. Orange slippers for an indoor party, orange sneakers if you're walking outside, and a plush egg or spotted basket to carry.
4. Women’s Yoshi Dress Costume
For a dress version, a green skater dress with a fitted bodice and a knee-length flared skirt keeps the shape playful. A white oval panel goes on the front and red felt spikes run down the back, with a small round red backpack as the shell so the skirt still swings. Green tights and orange ankle boots or flats carry the colour down. A high ponytail with a green ribbon or a smooth green bob wig both suit it. Green winged liner, peach blush and a glossy lip keep the face fresh. I'd attach the tail to a wide green belt rather than the dress itself, so its weight doesn't drag the back hem down. An eye headband and an egg purse finish it.
5. Glam Yoshi Costume
Sequins turn Yoshi into a party look. A fitted green sequin jumpsuit with a white satin belly and a detachable tail is the base; sequins are scratchy on the inside, so check the seams under the arms before you commit to a whole night in it. A round red mini backpack trimmed with white faux fur or piping becomes the shell. A sculpted green headband with raised eyes and little red spikes keeps your styled hair visible. Pair a sleek ponytail or glossy waves with emerald shadow, black liner and a peach lip. Orange platform boots nod to his feet, and a pearly egg clutch with green spots is the accessory.
6. Sporty Yoshi Costume
If you'll be moving a lot, go sporty. A green zip-up track jacket, matching leggings and a white tank underneath make an outfit you can actually run in. I'd attach the red felt spikes with snaps so the jacket goes back to normal afterwards, then clip a compact shell backpack over them. A green baseball cap with big felt eyes is the head, with your ponytail pulled through the back. Keep the tail slim and fixed at the waistband so it doesn't swing into your legs. Sweat-proof green liner, bright orange running shoes, fingerless gloves and a soft egg shaped like a small ball complete it.
7. Yoshi Overalls Costume
Green overalls are a great base because the white long-sleeve shirt underneath already suggests his pale belly, so there's no panel to sew. Red felt spikes go on the back straps and a round red backpack becomes the shell. A green beanie with padded eyes is the head, and a small stuffed tail clips to the back waistband. Low pigtails or a tucked braid fit under the beanie. Subtle green shadow, rosy cheeks and a plain lip keep it friendly. Orange high-tops bring in the shoes, and I'd turn a white treat bucket into the egg with big green spots, so the prop has a job.
8. Summer Yoshi Costume
On hot days, cut the layers. A green short-sleeve romper with a white fabric belly patch, a slim felt tail and small red spikes is plenty. A round red crossbody bag stands in for the shell. Skip the hood and use a visor or headband with soft eyes instead, because a fleece hood in the sun is miserable within an hour. Two braids or a bun keep hair off your neck. Waterproof green liner over sunscreen and a tinted balm will hold. Orange canvas sneakers or sporty sandals keep it light, and a hollow foam egg is the only prop you need for outdoor festivals.
9. Winter Yoshi Costume
For real cold, build Yoshi on top of winter gear. A green puffer jacket over a thermal top and green leggings or snow pants does the warming, and a white fleece belly panel goes on the jacket with Velcro or snaps so it comes off cleanly. Stuffed red spikes can run along a green knit hat and down the coat, with a red backpack as the shell. Tuck your hair into the hat. Moisturizing products, green mascara and cream blush cope better with cold air than powders. Orange insulated boots, green gloves and a tail stitched above the coat hem keep the outline clear.
10. Red Yoshi Costume
Red Yoshi stands out in any crowd, but it has one problem: the shell disappears into the body. The fix is a thick white border around the circular shell so it pops against the red. For the base, a red jumpsuit, fitted tracksuit or hoodie and pants all work, with a large white belly panel, orange or yellow back spikes and a rounded red tail. Orange sneakers and a red hood or beanie with padded eyes form the head and feet. Keep hair under the headpiece or choose a short red wig. Gold shadow and a coral lip suit the palette, and white gloves plus a red-spotted egg finish him.
11. Blue Yoshi Costume
Blue Yoshi is an easy swap that still looks like him. A royal-blue hoodie and joggers or a blue bodysuit make the body, with a white oval belly and orange-red spikes from the hood to the upper back. A red shell backpack trimmed in white and a stuffed blue tail at the waist finish the back. A hood with raised eyes gives the clearest head shape, though a blue wig and an eye headband also work if you hate hoods. Shimmery blue liner and peach blush tie the face in. Orange sneakers give strong contrast, and an egg with blue spots, or an egg-shaped bag, carries the theme.
12. Pink Yoshi Costume
Pink Yoshi is cheerful on anyone, from small kids to adults in a group. A bubblegum sweatshirt dress over leggings, or a hoodie and jogger set, makes the base, with a white fleece tummy, orange or red spikes and a rounded pink tail. The red-and-white shell gives contrast against all that pink. A pink hood with big fabric eyes suits any hair length, and two buns peeking below it look sweet. Rosy makeup and pink liner are kinder on the skin than full face paint. Orange sneakers or ankle boots and white gloves finish it, with a pink-spotted egg purse light enough to carry all evening.
13. Yellow Yoshi Costume
Yellow Yoshi is bright and easy to find in group photos. Build it on a yellow fleece jumpsuit or hoodie and sweatpants, add the white belly oval and orange or red spikes along the hood and back. A red shell with a wide white edge gives the strongest contrast. One thing I watch on yellow: regular orange shoes blend into the base, so choose a deeper burnt orange to keep the feet defined. Tuck hair under a yellow eye hood, or use a yellow bob wig with a padded eye band. Gold shadow and peach blush keep the face soft. A yellow tail, white gloves and a yellow-spotted egg finish him.
14. Black Yoshi Costume
Black Yoshi is the sleek option, and it's still friendly enough for kids. A black zip-front jumpsuit, or fitted top and pants, takes a bright white belly, red felt spikes and a red shell edged in white. A black hood with raised white eyes and a rounded stuffed nose makes him clear; without the nose, a black hood can look like a generic animal. Keep hair in a smooth low ponytail or wear a short black wig. Silver-green shadow and a muted red lip suit it. Orange combat boots bring colour to the bottom, and a black tail with a black-spotted white egg keeps the monochrome theme.
15. White Yoshi Costume
White Yoshi is unusual and very clean, but on a white base the white belly vanishes, so I use a pale gray belly patch to keep the front readable. A white fleece onesie, jumpsuit or hoodie and pants work as the body, with red spikes and a red shell bordered in white or silver. A white padded tail completes the shape. Tuck your hair away or wear a white wig under an eye headband. Pearl shadow, fine liner and pink blush keep the face fresh. Bright orange sneakers stop it looking washed out. White shows every mark, so choose fabrics you can throw in the washer.
16. Orange Yoshi Costume
Orange Yoshi feels festive without anything scary. An orange hooded jumpsuit with a white oval panel, red spikes, a stuffed orange tail and a red shell with thick white trim make the body. Because orange feet on an orange body disappear, choose golden-yellow sneakers or a deeper rust-orange boot instead. A padded eye hood gives the round head, with a low braid underneath. Copper shadow and peach blush suit the warm base, and white gloves keep the hands from blending in. A foam egg with orange spots can double as a light trick-or-treat container if you cut a lid in the top.
17. Purple Yoshi Costume
Purple Yoshi has bold colour blocking. A purple bodysuit, jumpsuit or sweatshirt and leggings take a bright white stomach and warm orange-red spikes. Position the red shell high on the back, above the tail, so it doesn't get hidden when you turn sideways. A purple hood with padded eyes, or a chin-length purple wig with an eye headband, makes the head. Lavender shadow, black liner and a light berry lip suit it. Orange sneakers or boots brighten the bottom half, and white gloves with a purple-spotted egg finish it.
18. Light Blue Yoshi Costume
Pastel blue is the softest version here. A light-blue hoodie dress with opaque tights, or a sweatshirt and jogger set, takes a white belly patch, coral-red spikes and a pale blue tail. Use a red shell with crisp white trim so the back doesn't fade into the pastel. A light-blue beanie with fabric eyes is the easiest headpiece, with loose curls or low braids. Icy blue shadow and peach blush keep it airy. Burnt-orange sneakers ground the pale palette better than a bright orange would, and a white bag with soft blue spots becomes the egg.
19. Yarn Yoshi Costume
The yarn version is for knitters and crocheters, and it nods to the woolly look of his own yarn-craft game. A green knit sweater with ribbed pants, or a crocheted-look jumpsuit, makes the base, with a cream yarn oval on the stomach and chunky red yarn spikes. For the shell I wrap a round cushion in red yarn and finish the edge with thick white cord. A crocheted green hat with dimensional eyes replaces a hood. Chunky yarn spikes droop if they're too long, so keep them short and stuff them firmly. Knitted orange shoe covers over sneakers, a braided tail, mittens and a yarn-wrapped ball egg finish it.
20. Crafted Cardboard Yoshi Costume
Cardboard Yoshi is a fun weekend build. Start with a green T-shirt and pants, then layer a boxy tunic of painted corrugated cardboard over them, with a white paper belly, flat red spikes and a shell made from stacked cardboard rings. A light headband with folded paper eyes is far easier to wear than a box helmet. Cardboard edges catch on hair and in crowds, so tie hair back and tape over every cut edge. Graphic liner and round pink cheeks suit the flat style. Cover old sneakers with orange paper panels and leave the soles bare so you don't slip. A folded tail and a papier-mache egg finish it, and keep it indoors if rain is likely.
21. Inflatable Yoshi Costume
An inflatable Yoshi gets the biggest reaction for the least effort. Look for a roomy green body with a white belly, red shell, orange feet and a big round head. These suits trap heat, so wear fitted shorts and a wicking top underneath. Secure hair in a low bun so it can't tangle near the fan or zipper. Makeup barely shows, so keep it light. Check that the viewing panel stays clear and that the hem doesn't cover your shoes, and put supportive sneakers inside the inflatable feet. Spare batteries for the fan are the one thing I'd never leave at home. A soft egg on a loop is all the prop it needs.
22. Yoshi Mascot Costume
A mascot-style Yoshi is the full transformation. It needs a padded green body with a white belly, a red saddle-style shell, a rounded tail and big orange shoe covers. The sculpted head should have a broad snout, large eyes, ventilation and soft red spikes. Wear a cooling cap under the head instead of a wig, and skip makeup since nobody sees your face. Thin gloves inside the costume hands help your grip. Practice walking in the padded feet before the day, because your sense of where your toes are goes out the window. In a crowd, bring a friend to guide you, and hold only a light egg.
23. Kids’ Yoshi Costume
For kids, softness matters more than accuracy. A green sweatshirt and elastic-waist pants make the base, with a white felt belly attached with fabric-safe fasteners and soft red fleece spikes on the hood. A small red backpack works as the shell. Keep the tail short and above the knees; anything longer gets stepped on within the first block. Leave their natural hair under the hood, with no tight pins or wigs. Face paint is optional, and a bit of washable green liner is enough. Orange sneakers, white mittens and a foam egg finish it, and I'd tug on every piece to make sure nothing comes loose.
24. Toddler Yoshi Costume
Toddlers need something warm that comes off fast for diaper changes. A green footless romper or zip-front fleece suit with a white tummy patch is the base. Sew soft red spikes onto the hood and upper back, keeping them small and flat so they don't push the child forward in the car seat. A flat felt shell is safer and lighter than a stuffed backpack. Leave hair natural under a loose hood, and skip makeup unless you use a tiny bit of child-safe cheek colour. Orange slip-ons with grippy soles, mittens and a short tail finish it, with a spotted treat bucket so both hands stay free.
25. Baby Yoshi Costume
For a baby, a soft one-piece with nothing loose is the only way I'd do it. A green cotton romper with a white oval tummy, fabric eyes on the hood and small red fleece spikes is plenty. Sew the shell as a flat red-and-white appliqué on the back rather than anything bulky. A tiny padded tail can sit above the diaper. Leave the baby's hair uncovered or use a loose hat that slips off easily, and skip makeup completely. Soft orange booties keep feet warm. For photos, set a plush egg beside the baby instead of in their hands, and take the hood off for naps.
26. Dog Yoshi Costume
Dogs can be Yoshi too, as long as the dog agrees. Start with a comfortable green pet hoodie or light dog shirt, then add a white fleece chest panel, soft red spikes along the back and a flat circular shell attached without tight straps. A small hood with fabric eyes is fine if it never covers the ears, eyes or nose. No makeup, dye or adhesives on the dog. Use their regular harness under or through the costume so the leash stays secure. Paw covers only work for a dog already used to booties. Keep the tail short and flexible, add an egg-print bandana, and take everything off at the first sign of discomfort.
27. Plus Size Yoshi Costume
A plus size Yoshi can be comfortable and fun to sew. A green jersey jumpsuit with a defined waist, or a longline hoodie with stretch leggings, makes a good base. Cut the white belly panel in proportion to the garment and use a soft fleece so it moves with you instead of sitting stiff across the front. Red spikes go along the hood and upper back, with a shell backpack on adjustable straps. A crown braid, curls or a low ponytail work around an eye headband. Green smoky liner and gloss give expression. Pick orange sneakers or cushioned flats for long nights, and an egg crossbody to keep essentials close.
28. Maternity Yoshi Costume
A rounded bump suits Yoshi's shape nicely. Start with a stretchy green maternity dress, or soft green overalls over a white top, and lay a removable white oval over the bump without any belts. A light red shell on the upper back and soft spikes on a green cardigan or hood finish the back. An eye headband is cooler than a full hood if you run warm. Fresh makeup with green liner and cream blush is plenty. Supportive orange sneakers are safer than heels, a small tail sits above the back hem, and I'd only carry the foam egg if your hands are otherwise free.
29. Couple Yoshi And Mario Costume
Yoshi and Mario is the classic pairing. The Yoshi wearer needs a green jumpsuit with a white belly, eye hood, red shell, tail, white gloves and orange sneakers. The Mario partner needs blue overalls, a red long-sleeve shirt, brown shoes, white gloves and a red cap with a white circle on the front. A thick brown mustache can be drawn with washable makeup or bought as a stick-on piece, and I'd test the adhesive on the arm first, since cheap glue can sting on the upper lip. Keep both hairstyles under the headwear. A spotted egg for Yoshi and a cardboard steering wheel for Mario make the scene.
30. Couple Green And Pink Yoshi Costume
Two Yoshis in different colours is the easiest couple costume to sew, because you only make one pattern twice. One person wears a green hoodie and joggers, the other a pink hoodie dress or matching set. Both need white bellies, red shells, soft spikes, tails and orange sneakers, with matching eye hoods or coloured wigs under eye headbands. Mirror the colours in your liner and cheeks. Each person carries an egg spotted in their own colour, and white gloves pull the pair together. Making one version sporty and one a little dressier keeps it from looking like two copies.
31. Yoshi Family Costume
A Yoshi family looks best when everyone takes a different colour. Green for one adult, red or blue for the other, and pink, yellow or light blue for the kids. Each outfit can be a hoodie and jogger set with a white belly, red shell, spikes, tail and orange shoes, which means you can cut all the bellies and spikes from the same pattern in one evening. Babies wear a simple romper, older kids and adults use eye hoods or padded headbands. Easy braids or buns fit under the headpieces. Light liner and cheek colour suit everyone except the baby, and matching spotted eggs make the photo.
32. Rainbow Yoshi Group Costume
A rainbow group gives every friend their own colour with one shared design. Hand out green, red, blue, pink, yellow, purple, orange, white or black, then build each look from a tracksuit, a white stomach panel, a round shell, red or orange spikes, a tail and orange shoes. Use padded eye headbands or hoods in each shade. Ponytails, braids or short wigs and liner matched to each colour keep the group tidy. Everyone carries an egg in their own spots, and white gloves tie the lineup together. Line up in colour order for photos, and keep each shell compact so friends can stand shoulder to shoulder without bumping.
33. Yoshi And Egg Duo Costume
Yoshi plus a giant egg is an easy duo that always gets a laugh. Yoshi wears the green jumpsuit, white belly, red shell, eye hood, tail, white gloves and orange sneakers. The egg wears a white tunic cut into a rounded oval over white leggings and sneakers, with big green felt spots front and back and arms and face left free. I'd sew the egg from two layers of fleece with thin foam between them, which keeps the shape but still bends when you sit; rigid cardboard won't let you sit at all. A white beanie and round green cheek dots finish the egg, and Yoshi carries a little basket.
34. Yoshi Racing Costume
Racing Yoshi turns the kart games into an outfit. A green mechanic-style jumpsuit with a white belly panel and checkered trim at the cuffs is the base, with red spikes at the shoulders, a small round shell and a streamlined tail. A green cap or a light foam helmet with raised eyes makes the head, as long as it doesn't block your view. A low ponytail and bold green liner suit it. Orange high-tops, white fingerless gloves and a cardboard steering wheel finish the look. Make the number patch from felt with a bit of Velcro so it comes off, and skip real brand logos.
35. Skeleton Yoshi Halloween Costume
Skeleton Yoshi is a little spooky and still fine for kids. Build it on a black or deep green jumpsuit, then cut white felt bones for the arms and legs. Felt bones on stretch fabric pucker if you glue them flat, so stretch the fabric slightly as you stitch or use a fabric glue that stays flexible. Add the white belly, red spikes, shell and rounded tail, with a black-and-green hood and padded eyes. Tuck hair under the hood. Draw simple curved lines on the cheeks with white face paint and add green shadow, nothing realistic. Orange high-tops, bone-print gloves and a black egg with green spots and glow stars finish it.
Red Spikes That Stay Upright
Floppy spikes are the usual weak spot on a homemade Yoshi. A spike that stands up at home is lying flat by the third street of trick-or-treating, because the stuffing settles and the base gets bent by every hug and car ride. This is how I sew them so they hold.
- Cut each spike as two triangles of red fleece, with a wide base and a short height. Wide and short stays up; tall and narrow tips over.
- Sew the two long sides, turn it right side out and push the point out with a chopstick.
- Stuff firmly, packing the tip first. Loose stuffing is why spikes go flat.
- Close the base and stitch each spike to a single strip of red fabric, then sew that strip down the hood and back in one line. One strip is quicker than sewing every spike on separately and keeps them evenly spaced.
- For a child's costume, keep spikes small near the neck so they don't press into the back of the head in a car seat.
If you want it removable, sew the strip onto Velcro instead of directly onto the hoodie. The hoodie goes back to everyday wear and the spikes wait in a bag for next year.
Six Parts Make Any Yoshi Work
Every version here comes back to the same six parts: the white belly, the raised eyes, red spikes, a round shell, a tail and orange shoes. Get those right and a plain hoodie reads as Yoshi just as well as a full mascot suit. Green is the classic, but the other colours are what make a group or family photo fun. Fleece, felt, foam and a cheap backpack keep costs down and the costume light. For little ones, shorten tails, flatten shells and skip anything loose. If I were sewing just one, I'd make the green hoodie version first; it's a good evening's work and it'll get worn long after Halloween.
