Nepeta Leijon is one of the friendliest Homestuck characters to dress as, because her outfit is mostly ordinary clothing with a few cat details on top. The core pieces are a black shirt with her green Leo symbol, an oversized olive-green coat, gray pants, a blue cat hat, a tail, short dark hair and blue shoes. Get those right and you have a lot of room to play. You can sew a screen-accurate version, rework thrifted pieces, or move her into punk, cottagecore, formal or futuristic dress. If you add the gray troll skin, use cosmetic-grade paint and set it well so it doesn't end up on the coat. Light horns, soft claws and flexible props make busy halls far easier to move through. Below are thirty ways to wear her, from the classic coat to a rainy-day raincoat.
Building a Cat Hat That Holds Its Horns
Nearly every version below hangs on the blue cat hat, and the horns are what make it a troll's hat rather than a cat's. The common mistake is gluing horns to the wig. They twist the first time you look over your shoulder, and the wig shifts with them. I mount them on the hat instead, so hat and horns move as one piece.
- Start with a fleece beanie or a simple hat sewn from two curved fleece panels. Fleece doesn't fray, so raw edges are fine on the inside.
- Cut each ear as two layers with a layer of stiff interfacing between them, then stitch round the edge. Single-layer ears flop by the end of the day.
- Shape the horns from lightweight foam or air-dry clay over a foam core, then paint the orange-to-yellow stripes. Nepeta's horns are short and rounded, so keep them small.
- Glue each horn to a felt base about the size of a coin, then stitch that base to the hat through the fleece. Hot glue straight onto fleece peels away once it cools.
- Wear the hat over the wig with two or three bobby pins through the brim at the sides. A wig cap underneath gives the pins something to grip.
Make the hat a size too snug rather than too loose. Fleece relaxes as it warms, and a hat that starts loose will be sitting on your eyebrows by the afternoon.
1. Classic Nepeta Cosplay With Green Coat
This is the version people expect, so I'd make it first if you only make one. Wear a black T-shirt with her green Leo symbol, straight gray pants and an oversized forest-green coat. A short, shaggy black wig goes under a bright blue cat-ear hat, with light striped horns fixed to the hat rather than the wig so they don't twist when you turn your head. Gray face and neck makeup gives the troll look; softly drawn lower lashes and black lipstick define it. Blue sneakers, fingerless paw gloves and a long blue fabric tail sewn or clipped firmly at the waistband bring in the cat. A small shipping notebook is the right prop for her, light and in character. Keep the coat roomy but stop the hem above the ankle, or you'll tread on it on every staircase.
2. Easy Nepeta Cosplay With Closet Clothes
You don't need to sew a new wardrobe for a recognisable Nepeta. A plain black tee with a hand-painted green Leo symbol, charcoal jeans, blue canvas sneakers and any roomy olive utility jacket covers the silhouette. Use a short black wig, or style your own hair into choppy layers. A blue beanie turns into her cat hat once you add felt ears and small foam horns; fabric glue holds on a knit beanie, but a few stitches at each ear corner stop them peeling off when the beanie stretches over your head. Light gray makeup, black lipstick and a few faint whisker marks finish the face. Clip a blue tail to the back of the jeans and wear navy fingerless gloves with soft felt claws. A notebook full of character pairings makes the simple outfit look like a choice, not a scramble.
3. Casual Nepeta Cosplay With Blue Hoodie
Swapping the coat for an oversized blue cat-ear hoodie makes Nepeta about as comfortable as cosplay gets. Wear it over a black Leo shirt with gray joggers and supportive blue high-tops. The small striped horns can come through two openings beside the hood's ears; I reinforce those holes with a ring of iron-on interfacing, because knit fabric runs and stretches around a cut. A tousled black bob wig and softer gray makeup, lighter around the eyes, suit the relaxed mood. Blue paw gloves and a flexible tail keep the cat theme without getting in the way. A green crossbody pouch with paw patches holds your essentials. Every piece comes off easily, which matters when a hall swings from chilly to stuffy.
4. Winter Nepeta Cosplay With Fleece Coat
When the event is cold, I keep Nepeta's colours and simply thicken every layer. A knee-length forest-green fleece coat goes over a black thermal top with a green Leo emblem, gray lined leggings and insulated blue ankle boots. Make the cat hat from thick blue fleece with padded ears and light striped horns. A short black wig tangles less under a snug hat than a long one would. Gray face makeup, black lipstick and soft green shadow handle the face. Blue knit gloves with small felt claw tips stay warm, and the stuffed tail attaches to the coat, not the pants, so it still shows over the layers. A green faux-fur collar adds warmth and texture, and the whole look still reads as her coat and hat from a distance.
5. Summer Nepeta Cosplay With Green Vest
A full coat in summer heat is miserable, and this vest version keeps Nepeta recognisable without it. Layer a sleeveless olive utility vest over a black Leo tank, add loose gray knee-length shorts and bright blue sneakers with ankle socks. A breathable blue cat-ear cap with foam horns sits over the short black wig. If your arms show, they'll need gray too, and that's where heat bites: apply thin layers and set each one with powder, because a thick layer of cream paint slides once you sweat. Blue fingerless gloves, a light fabric tail and a small green belt pouch keep the details. A handmade shipping chart on a clipboard is a prop that weighs almost nothing. The palette and cat details stay, but you get real airflow.
6. Cute Nepeta Cosplay With Pleated Skirt
A pleated skirt softens Nepeta nicely, and her coat becomes an oversized green cardigan. Wear it over the black symbol shirt with a charcoal pleated skirt, opaque gray tights and blue lace-up sneakers. The fluffy blue cat-ear hat, short black wig and neat striped horns frame the face. Smooth gray makeup, rounded black liner, a few painted freckles and a muted black lip give an animated look. Blue paw gloves and a plush tail with wire inside, so you can bend it into a curl, carry the cat shape. A green satchel holds a decorated shipping notebook and pens. I'd keep the skirt at about knee length; it sits better with the bulky cardigan and is easier at family events.
7. Punk Nepeta Cosplay With Plaid Pants
Punk suits Nepeta better than you'd think, since her coat already looks a bit like a battered army jacket. Wear a black Leo graphic tee, a dark green distressed jacket and gray-and-blue plaid pants. Blue combat-style boots give a heavy base. A shaggy black wig with a few temporary green streaks sits under a blue cat-ear beanie with compact striped horns. Gray makeup, smudged black liner and deep charcoal lipstick make the face dramatic without going grisly. Add blue fingerless gloves, a studded fabric cuff and a long blue tail with removable plaid bows. A notebook covered in band-style stickers is the prop. Keep any metal studs few and rounded; sharp points catch on other people's costumes in a crowd, and on children's hair.
8. Goth Nepeta Cosplay With Black Dress
A black skater dress gives gothic Nepeta a neat base. Put a dark green Leo emblem across the bodice and wear the dress under a long moss-green coat, with gray tights and blue platform sneakers on soles you can still walk in. A textured black bob wig goes under a dark blue velvet cat hat with striped foam horns. Velvet sheds tiny fibres and shows every crease, so steam it before you leave and keep a lint roller in your bag. Gray base, precise black liner, charcoal lipstick and a touch of cool green shadow suit the dress. Blue velvet paw gloves and a curved tail soften all that black. A small black notebook tied with green ribbon is a quiet prop. It stays moody and theatrical without anything gory.
9. Glam Nepeta Cosplay With Sequin Jacket
Sequins work on Nepeta if you keep them in one place. Start with a fitted black top carrying a sparkling green Leo symbol, tailored gray trousers and a cropped emerald sequin jacket. Metallic blue ankle boots tie in with a satin blue tail and matching fingerless gloves. Style the black wig into a glossy layered bob and add a structured blue cat-ear headpiece with light striped horns. Gray base, silver-green shadow, long lashes and glossy charcoal lips carry the glamour. A glitter-covered shipping journal and a compact blue belt bag finish it. Sequins scratch the inside of the arm where the sleeve rubs, so a long-sleeved top under the jacket helps. Keep sparkle to the jacket and emblem and the outfit stays coordinated rather than loud.
10. Formal Nepeta Cosplay With Green Suit
For a masquerade or a cosplay dance, tailoring lets Nepeta dress up without losing her. Wear an emerald suit: a black blouse with a subtle green Leo emblem, fitted gray trousers and a green blazer with blue lining, which flashes her blue whenever the jacket moves. Polished blue loafers are kinder than heels for a long evening. A neat black bob wig and a small blue fascinator shaped with cat ears, striped horns and a short veil make the headpiece. Smooth gray makeup, softly winged liner and satin black lipstick suit the formality. Attach a narrow blue tail under the blazer and wear dark blue gloves. A structured notebook clutch with tiny green symbols is the last touch. She stays recognisable without any cartoon proportions.
11. Cottagecore Nepeta Cosplay With Green Pinafore
Nepeta lives outdoors and hunts, so a woodland cottagecore version fits her nature. Layer a moss-green pinafore dress over a black puff-sleeve blouse with a small Leo emblem. Gray ribbed tights and blue lace-up boots take care of the legs. A wavy black bob wig sits under a knitted blue cat-ear bonnet with compact striped horns; a bonnet that ties under the chin holds far better than a hat that just perches. Light gray makeup, faux freckles, green shadow and a muted charcoal lip keep it gentle. Blue paw mitts, a soft tail and a woven crossbody basket round it off. Fill the basket with faux leaves, yarn balls and a tiny shipping notebook, not real leaves and twigs, which crumble and leave a trail everywhere you sit.
12. Dark Academia Nepeta Cosplay With Plaid Blazer
Scholarly Nepeta starts with a black button-up shirt, a green-and-gray plaid blazer, charcoal pleated trousers and blue oxfords. An embroidered Leo patch on the shirt pocket identifies her straight away. Curl the ends of a short black wig slightly and set a blue cat-ear beret on top, with the striped horns at the sides; berets slide back on smooth wig fibre, so a couple of bobby pins through the band help. Gray makeup, softly shaded eyes and black lip stain keep the face neat and bookish. Blue fingerless gloves, a slim tail and a brown satchel holding a green-covered shipping journal complete it. Round glasses are optional. It's polished enough for indoor photos and easy to walk around in all day.
13. Streetwear Nepeta Cosplay With Cargo Pants
Streetwear is a natural update for Nepeta's practical clothes. Wear an oversized black Leo sweatshirt under a cropped green utility jacket, with baggy gray cargo pants and chunky blue sneakers. A black wolf-cut wig gives movement around a fitted blue cat-ear cap and short striped horns. A sheer gray base, graphic black liner and dark lip tint make a clean modern face. Attach a padded blue tail to the cargo waistband with a sturdy clip, since heavy cargo fabric pulls down on a weak one. Paw-style fingerless gloves, a green crossbody bag and blue headphones are all things you'd carry anyway. A pocket shipping notebook is the prop. The loose shapes look intentional and let you move freely for hours.
14. Techwear Nepeta Cosplay With Utility Harness
Techwear gives Nepeta a futuristic edge that's still just clothing. Combine a black Leo mock-neck with gray tapered cargo pants, a dark green technical jacket and blue high-top boots. A light green utility harness over the jacket adds structure; use its pouches for your actual things rather than fake gear. The short black wig sits under a streamlined blue hood with pointed cat ears and striped foam horns. Smooth gray makeup, sharp geometric liner and matte black lipstick suit the clean lines. A segmented blue fabric tail suggests machinery without any hard parts. Fitted blue gloves, reflective green trim and a shipping chart shown on a tablet case finish it. Make every attachment soft and quick to undo for bag checks at the door.
15. Cyberpunk Nepeta Cosplay With Neon Blue Accents
Neon blue turns Nepeta cyberpunk without changing who she is. Start with a fitted black Leo top, gray panelled pants, an emerald cropped coat and blue light-up sneakers. A jagged black bob wig goes under a sculpted blue cat-ear headpiece with striped horns. Gray face makeup, fluorescent green liner and glossy black lips carry the colour, with removable blue face decals near the temples. Decals peel at the edges on oily skin, so press them on after powder, not before. A long blue tail with reflective piping, fingerless gloves, a green belt pouch and translucent blue visor glasses build the rest. A slim illuminated notebook is the prop. Go easy on battery accessories; each one adds weight and something else to switch off and charge.
16. Steampunk Nepeta Cosplay With Green Tailcoat
Steampunk drops Nepeta into a mechanical adventure. Wear a black high-neck blouse with a brass-toned Leo emblem, fitted gray trousers, a green tailcoat and blue lace-up ankle boots. A short curled black wig sits under a blue cat-ear cap trimmed with plastic gears and small striped horns. Gray makeup, softly smoky eyes and black lipstick give the troll base. Blue fingerless gloves and a fabric tail with light gear appliqués tie the cat to the theme. Round goggles worn up on the hat and a weathered shipping journal tied to the belt finish it. Painted craft foam gives you the same brassy look as metal at a fraction of the weight, and nothing sharp to snag a passer-by.
17. Magical Girl Nepeta Cosplay With Green Skirt
Magical-girl Nepeta stays close to her palette with more sparkle and a cape. Choose a fitted black top with a large green Leo emblem, a layered emerald skirt, gray tights and blue knee-high boots. A short green cape with blue trim and a bow at the collar adds the magical-girl shape. The black bob wig goes under a blue cat-ear headband with striped horns. Gray makeup, sparkling green shadow, small star decals and glossy charcoal lips give the face its shine. Blue paw gloves and a ribbon-wrapped tail keep her a cat. A soft wand topped with a foam Leo symbol and yarn balls is a safe prop. Line the skirt so the tulle doesn't scratch, and keep the cape short enough that you can't step on it.
18. Royal Nepeta Cosplay With Green Cape
Royal Nepeta is the most formal on this list, and the most work to walk in. A floor-skimming emerald dress sits over gray tights and blue flats, with an embroidered green Leo emblem on the black bodice and a rich green cape clasped at the shoulders with blue fabric. A light blue crown shaped with cat ears and striped horns replaces the hat over the short black wig. Gray base, elegant black liner, soft green shimmer and dark satin lipstick suit the gown. Elbow-length blue gloves and a plush tail carry the cat details. A small royal decree drawn like a shipping chart is a funny prop. I'd hem the dress an inch off the floor and make the crown from flexible foam, so neither suffers in a long photo queue.
19. Fairy Nepeta Cosplay With Green Wings
Nepeta's playful streak suits a woodland fairy. Start with a black Leo bodysuit or tucked top, a layered green knee-length skirt, gray tights and blue ankle boots. Translucent green wings with rounded edges and blue ribbon add the fairy. The tousled black wig goes under a flower-trimmed blue cat-ear headband with light striped horns. Gray makeup, leafy green shadow, delicate freckles and charcoal lips give the face. Blue paw gloves, a slim tail and a tiny belt pouch keep her character. A yarn ball wrapped in shimmering ribbon is the prop. Wings wider than your shoulders hit people every time you turn, so keep them compact; they still look magical in a full-length photo.
20. Idol Nepeta Cosplay With Stage Jacket
Idol Nepeta is built for posing. A cropped emerald performance jacket goes over a black Leo top, with a gray pleated skort and glittery blue ankle boots. Gray tights give coverage under the skort, which matters once you start kicking and spinning. Style the black bob wig with playful side clips and set a blue cat-ear headset around small striped horns. Gray makeup, sharp green liner, a little cheek shimmer and glossy black lipstick read well on camera. A blue tail with removable bows swings nicely in motion, and fitted paw gloves keep the cat. A toy microphone covered in blue foam is the prop. Every piece moves with you, which is what a dance or showcase needs.
21. Pajama Nepeta Cosplay With Cat Onesie
For a cosy meetup or a sleepwear-themed night, a blue cat onesie is the base. Wear a black Leo T-shirt underneath so she's still Nepeta when you unzip it halfway, which you will once the room warms up. The hood holds padded cat ears and small striped horns, so you don't need a separate hat. A short black wig, soft gray makeup, rounded black liner and tinted charcoal lip balm keep the face easy. Blue paw slippers and an attached plush tail carry the cat. A green blanket roll and a shipping notebook in a fabric pouch suit the theme. If you'll walk through public areas, pick slippers with rubber soles; plain indoor ones slip on polished floors.
22. Chibi Nepeta Cosplay With Oversized Coat
Chibi Nepeta exaggerates every proportion. Pair a large forest-green coat with a black Leo shirt, cropped gray pants and chunky blue sneakers. An extra-fluffy black bob wig goes under a padded blue cat hat with oversized ears and compact striped horns. Smooth gray makeup with rounded liner, pale highlights and soft lower lashes enlarges the eyes. Big blue paw mitts and a thick plush tail push the cartoon shape. An oversized foam shipping notebook looks dramatic in photos and still weighs next to nothing. The balance is tricky: shorten the coat sleeves so the mitts show, and keep the headpiece from creeping down far enough to cut off your view. Big padded ears grow heavy, so stuff them with polyfill rather than foam blocks.
23. Retro Nepeta Cosplay With Flared Pants
A 1970s Nepeta pairs a fitted black Leo turtleneck with high-waisted gray flares and a cropped moss-green jacket. Blue platform shoes with broad, stable soles give the period height without wobbling. Style the black wig into a rounded layered bob and add a blue cat-ear headband with striped horns. Gray makeup, winged black liner, muted green shadow and glossy charcoal lips suit the decade. Blue fingerless gloves and a long, gently curved tail stay in character. A green shoulder bag with flower patches carries a compact shipping journal. Flares drag on the ground if they're hemmed for flat shoes, so hem them while wearing the platforms. The flare and the cropped jacket do the dating; the colours and cat details keep it Nepeta.
24. Y2K Nepeta Cosplay With Gray Cargo Skirt
Early-2000s Nepeta is a fun excuse for a baby tee and a cargo skirt. Pair a fitted black Leo baby tee with a gray cargo midi skirt, a cropped green jacket and bright blue platform sneakers. Blue arm warmers and a tail fixed under the jacket keep the colour going. Flip the ends of the short black wig and add snap clips, with a blue cat-ear beanie holding small striped horns. Light gray makeup, thin black liner, green shimmer and glossy charcoal lips fit the era. A small green shoulder bag with paw patches and a fuzzy yarn-ball charm, plus a shipping notebook, are the props. Stop there: three Y2K references read as a costume, but eight just look like a pile of trends.
25. Festival Nepeta Cosplay With Green Fringe Jacket
An outdoor festival is no place for heavy fabric or loose pieces. Wear a black sleeveless Leo top, loose gray shorts, a light green fringe jacket and blue high-top sneakers. Gray knee socks add coverage and echo her gray pants. A short black wig sits under a blue cat-ear bucket hat with soft striped horns; a bucket hat shades the face and protects the makeup from the sun. Keep the gray base minimal, with waterproof liner and dark lip stain. Blue fingerless gloves and a firmly clipped fabric tail finish the cat. A green hydration backpack with removable paw patches hides a tiny shipping notebook in its pocket. Leave the loose glitter at home and skip anything fragile that could drop off while you're dancing or sitting on grass.
26. Rainy Day Nepeta Cosplay With Green Raincoat
Rain doesn't have to ruin Nepeta; the raincoat can be the coat. Wear a forest-green hooded raincoat over a black Leo sweatshirt and straight gray waterproof pants, with blue rain boots and cushioned socks. A short black wig, or your own hair tucked away, goes under a removable blue cat-ear cover that fits over the hood. Fix the light striped horns to that cover instead of the wig, so a soaked hood doesn't take the wig with it. Water-resistant gray makeup, black liner and a tinted dark lip hold up better in damp air. Blue waterproof gloves and a stuffed tail made from coated fabric resist soaking through. A clear document pouch keeps the shipping chart dry. It's the version to pick for outdoor parades and shoots when the forecast is uncertain.
27. Convention Nepeta Cosplay With Comfortable Sneakers
When you'll be on your feet from morning to evening, build Nepeta around comfort first. Wear a breathable black Leo tee, stretch gray trousers, a lightweight green overshirt and supportive blue running-style sneakers. A ventilated black bob wig and a soft blue headband carrying cat ears and hollow foam horns keep the head cool. Apply gray only where skin shows, then black liner and a transfer-resistant charcoal lip. Fingerless gloves leave your fingers free for phones and badges, and a light detachable tail won't drag when you sit. A green backpack holds water, touch-up makeup and the shipping notebook. Use clips you can undo in seconds for the tail and headpiece. You'll still look like her in photos at the end of the day, and feel fine.
28. Gender-Neutral Nepeta Cosplay With Oversized Layers
Nepeta's original clothes are already close to gender-neutral, so this version mostly loosens the fit. Wear a boxy black Leo shirt, relaxed gray cargo trousers, an oversized green field jacket and blue high-tops. A short textured black wig can be styled without leaning feminine or masculine. A structured blue cat-ear cap, light striped horns and a long fabric tail keep her character. Gray makeup, subtle black liner and matte charcoal lips give the troll finish, and you can make it as strong or as faint as you like. Blue fingerless gloves and a green crossbody pouch round it off, with a hand-decorated shipping journal as the prop. Loose layers suit a wide range of bodies, and every piece adjusts without losing her look.
29. Masculine Nepeta Cosplay With Green Utility Jacket
A masculine Nepeta keeps every signature detail and simply changes the cut. Pair a black Leo muscle tee or crew-neck with straight gray work pants, a structured green utility jacket and blue lace-up boots. A short, messy black wig sits under a close-fitting blue cat-ear cap with striped horns. Gray makeup across visible skin, with strong black brows, subtle liner and matte charcoal lips, suits the stronger lines. Blue fingerless gloves, a thick fabric tail and a broad green belt carry the details. A weathered notebook of hand-drawn relationship charts is the prop. Straight, practical garment lines do more here than tight fits. It reads as Nepeta immediately and gives a comfortable, traditionally masculine take on her outfit.
30. Plus Size Nepeta Cosplay With Custom Green Coat
The coat is the piece to get fitted for a plus size Nepeta, because an oversized coat that pulls at the bust or upper arm looks small rather than oversized. Choose a black stretch-knit Leo shirt, gray straight-leg trousers with an elastic back waistband and a tailored green coat that closes without strain. Blue cushioned sneakers keep long events bearable. A breathable black bob wig and a soft blue cat hat with light striped horns finish the head. Cosmetic-grade gray makeup, softly winged liner and transfer-resistant black lipstick handle the face. Adjustable blue paw gloves and a tail on its own belt stop accessories pulling the clothes out of place. A roomy green crossbody bag carries the shipping notebook. Good tailoring keeps her playful big-coat shape where it should be.
Gray Troll Skin Without a Gray Coat Collar
The gray makeup is optional, but most of these looks use it, and it's where people run into trouble. I'm talking about everyday costume makeup here, not professional effects, and the same few habits prevent most problems.
Test it a few days early
Use paint labelled for skin, not craft paint, and try a small patch on the inside of your wrist or behind the ear a day or two before. If it itches or reddens, don't wear it on your face. A test run at home also shows how long a full face takes, which is usually longer than you think.
Thin layers and plenty of powder
Water-activated paint dries harder and transfers less than cream, while cream blends more easily on dry skin. Either way, two thin layers beat one thick one. Press translucent powder over each layer with a puff and let it sit before you brush off the excess. A setting spray at the end helps on warm days.
Protecting the coat and gloves
The green collar takes the worst of it, because the jaw and neck rub against it every time you turn your head. Stop the gray just below where the collar sits, or tuck a thin black scarf or high-neck shirt in between. Paw gloves mean you don't have to paint your hands at all, which saves time and keeps the gray off everything you touch.
To take it off, massage in an oil cleanser or balm, wipe gently and then wash with your usual cleanser. Scrubbing hard leaves skin raw the next day and doesn't shift the pigment any faster.
Blue Hat, Gray Skin and a Green Coat Come First
Nepeta's colours and cat details stretch across a surprising range of styles. Stay close to the classic green coat and gray pants, or take her into streetwear, tailoring, the 1970s, cottagecore or something futuristic. Whichever way you go, the same handful of pieces carry her: a black Leo top, dark hair, striped horns, blue cat accessories, sensible shoes and a light prop. Test your makeup a few days before, fix the tail properly, and check that the headpiece leaves your view clear. Accuracy matters less than you'd think. A Nepeta that fits, photographs clearly and stays comfortable for the whole day is the one people remember.
