Diluc is one of the friendliest Genshin characters to sew for, because his whole identity sits in three things: a long red ponytail, dark tailored layers and touches of flame red. Get those right and you can move him into almost any setting. His default outfit is a layered black coat with red trim, and his Red Dead of Night alternate turns the red up and lifts the ponytail higher. The thirty versions below run from game-accurate builds to closet pieces, formal redesigns, seasonal outfits, gender-bent takes and alternate-universe ideas, and I've noted where the sewing gets fiddly and where you can cheat.

Turning a Cheap Red Wig Into Diluc's Ponytail
Every version below relies on the hair, and a long red wig straight out of the bag rarely looks like his. Here's how I get it there.
- Buy a long wig with a lace front or at least a soft hairline, and pick a true crimson rather than orange or pink. Diluc's red is deep, close to wine at the roots.
- Put the wig on a head form and detangle from the ends upward with a wide comb. Synthetic fibre snaps if you rip through tangles from the top.
- Gather a low ponytail at the nape and secure it with a hair tie, then wrap a thin strip of the wig's own hair around it to hide the band.
- Trim the bangs to just below the eyebrows, cutting vertically into the ends so they look feathered rather than blunt.
- Hold the sides in place with a little hairspray, and keep the fibre away from hot tools unless the label says it's heat-safe.
On the day, a wig cap and a few bobby pins through the ponytail base stop the whole thing sliding back. Long synthetic wigs tangle where they rub against a coat collar, so a light spritz of anti-static spray before you go out saves you a lot of combing later.
What His Claymore Should Really Be Made Of
Diluc's weapon in the game is a huge claymore, and many people want it in photos. If you make one, use EVA foam over a lightweight core such as a PVC pipe or wooden dowel, seal it, then paint. Foam is light enough to carry all day and won't hurt anyone if it knocks into them. Check the event's prop rules before you build, because many limit length or ban anything with a hard core, and some ask that props be peace-bonded or checked at the door. If the rules or the crowd make it awkward, the smaller props suggested throughout this list carry the character just as well.
1. Classic Diluc Cosplay

His default look is the black coat, dark vest, white high-collar shirt, slim black trousers and knee-high boots. The details that sell it are the red piping, silver trim, buckles and the faux fur at one shoulder. When I build this, I sew the piping into the seams rather than gluing it on top; glued trim lifts at the curves within an hour of wear. Style the crimson wig in a loose low ponytail with layered bangs. A lightweight flame accessory or a plush falcon is easier to carry around all day than his full claymore.
2. Red Dead Of Night Diluc Cosplay

Red Dead of Night is the sharper alternate outfit: a fitted black base, structured crimson coat, dark trousers and tall black boots, with the hair pulled into a high ponytail. The angular shoulder panels are where I'd use EVA foam, heat-shaped over a curved bowl and covered in fabric, because craft foam is too thin to hold that crisp edge. Dark metal-look clasps and layered belts go on next, then flame-shaped red accents along the coat. Keep the makeup to smoky red-brown eyes and a little contour. A coded letter or a small faux fire orb finishes it without a heavy prop.
3. Darknight Hero Diluc Cosplay

The Darknight Hero is Diluc's secret night-time identity, so this version hides him without losing the hair. A long black hooded coat over a charcoal shirt, slim trousers and sturdy boots is the base. I line the coat with dark red so it flashes when you walk; a contrast lining is the cheapest way to add movement to a plain coat. A simple black half-mask works better than a full one, since full masks narrow your view in crowds. Add gloves, a utility belt and a battery-powered red lantern, which is much safer than anything with a flame.
4. Manga Diluc Cosplay

The manga Diluc is a younger, cleaner take. A fitted black military-style jacket with silver buttons, a white stand-collar shirt, dark riding trousers and polished boots form it. A short red capelet over the shoulders adds colour up top. A capelet is also one of the easiest garments to sew: a half circle with a slit and a collar band, and an afternoon's work. Use a softer, less voluminous wig tied low. Because there's no heavy coat, this is a sensible pick if the hall will be hot or you'll be posing for a long time.
5. Bartender Diluc Cosplay

Diluc tends bar at the Angel's Share tavern, so this outfit is part of his story. A crisp white shirt, fitted black vest, black trousers and leather-look shoes cover it. Roll the sleeves neatly to the elbow and add dark red arm garters; I make those from wide elastic covered in a tube of satin, and they take minutes. Tie the wig into a practical low ponytail. Gloves look good in photos, but bare hands read more like a real bartender. A black apron and a tray with a grape or berry juice finish it.
6. Dawn Winery Owner Diluc Cosplay

As owner of the Dawn Winery, Diluc gets to dress like landed gentry. A burgundy frock coat, black brocade vest, ivory high-collar shirt, tailored trousers and riding boots set the tone. Brocade frays fast, so I'd finish every cut edge before sewing the vest together, either with an overlocker or a zigzag. Gold buttons, a dark red pocket square and a smooth low ponytail tied with black ribbon complete the gentleman. Carry an account book, a key ring or a rolled estate map; I'd skip the wine glass, which the character himself famously avoids.
7. Easy Closet Diluc Cosplay

This is the version to throw together from your own wardrobe. A long black coat, white button-down, black jeans, a dark vest and lace-up boots are the base. Red ribbon along the coat edges held with fabric tape gives the trim without damaging the coat. The wig matters most here; even a budget one tied into a loose ponytail does more work than any other piece. Everyday makeup with brown liner and muted red shadow is plenty. Winter gloves, a red crystal necklace and a printed flame emblem connect the rest.
8. Budget DIY Diluc Cosplay

A thrifted black trench coat is the best start for a budget build, because the long line already looks like his coat. Add dark trousers, a white dress shirt and plain boots. I make the red edging from bias tape, which bends around curves without puckering the way straight ribbon does. Silver clasps can be cut from craft foam and painted. Attach the faux fur at one shoulder with snaps or hook-and-loop so it comes off for washing. Trim the bangs on a cheap wig a little at a time, cutting into the ends rather than straight across.
9. Last-Minute Diluc Cosplay

One evening is enough for this one. An all-black outfit does the heavy lifting: a black blazer or long cardigan over a white high-neck top, fitted black trousers and ankle boots. Red then comes in through the hair and accessories. A red wig in a low ponytail is fastest; temporary red hair colour works on naturally long hair but can stain pale pillowcases. Brown liner with burgundy shadow at the outer corners gives his serious look. Two crossed belts at the waist and a red LED tucked inside a clear ornament make a safe elemental prop.
10. Female Diluc Cosplay

For a female Diluc I keep the authority of the original and adjust the tailoring. A structured black coat over a white high-collar blouse, a fitted waistcoat, slim trousers or leggings and knee-high boots with stable block heels form the base. If you're sewing the waistcoat, add a little shaping with darts or princess seams rather than just taking in the side seams, which pulls the front off grain. Red piping, silver clasps and a faux fur shoulder piece carry the details. Sculpted brows and smoky burgundy eyes with a neutral lip keep the expression stern.
11. Plus-Size Diluc Cosplay

On a plus-size build, the fit of the coat matters more than any trim. I'd look for a long black coat that closes across the chest and hips without straining, because pull lines at the buttons are the first thing a camera picks up. A stretch waistcoat, breathable shirt, dark trousers and wide-fit boots go under it. Running the red trim vertically down the front edges draws the eye along the length of the coat. Use flexible foam for the shoulder pieces and a low-pile faux fur so you don't add bulk. An adjustable wig grip keeps a long, heavy wig steady.
12. Summer Diluc Cosplay

In real heat, the full coat is miserable. I swap it for a sleeveless black vest over a short-sleeve white shirt, tailored shorts or cropped trousers and ankle boots. Narrow red trim along the vest and a detachable half-cape for photos keep the character. Choose a wig with less fibre, since thick synthetic wigs trap heat like a hat. A waterproof liner and sweat-resistant base hold up better than regular makeup. Fingerless gloves keep the dark colour on your hands while letting them breathe, and a folding fan with flame shapes is both prop and relief.
13. Winter Diluc Cosplay

A cold day is the easiest time to wear Diluc, because his look is all layers anyway. A fitted black turtleneck under a long dark coat, wool-blend trousers and insulated knee-high boots keep you warm. I line the coat opening with deep red and add removable faux fur at the shoulders and cuffs; fur stitched permanently to a coat is a pain to clean. A loose low ponytail with a few curled strands softens the face. Thermal gloves, a red scarf and a closed LED lantern give you warmth plus a prop.
14. Modern Streetwear Diluc Cosplay

This streetwear Diluc is for casual meetups where full tailoring would feel like too much. A black bomber over a charcoal turtleneck, slim cargo trousers and high-top black sneakers form the outfit. Burgundy panels, silver zipper pulls and a red utility strap echo his coat trim. Skip a hat; the red hair is the main clue that this is Diluc and should stay visible. Fingerless gloves, a crossbody satchel and a flame keychain are useful as well as on theme. Carry a lit red sphere for photos.
15. Formal Suit Diluc Cosplay

A fitted three-piece suit makes a clean modern Diluc. A black suit, ivory shirt, burgundy tie and black boots are the frame. His coat is long, so I either choose a jacket with a longer cut or sew a detachable back panel that buttons under the vent. Silver cuff links, red piping and a flame lapel pin add the fantasy layer. Smooth the wig and tie it low with a black ribbon. Gloves are for posed photos only. A leather-look folder or sealed invitation is the prop, and the whole build needs far less construction than armour.
16. Knight Diluc Cosplay

Diluc once served in the Knights of Favonius, so a knight version suits his history. A fitted black tunic, long red-lined coat, dark trousers and riding boots form the base. The chest panel, shoulder guards and bracers should be EVA foam, sealed and painted silver; real metal is heavy and loud in a crowd. Keep the armour narrow so your arms can still swing. A low ponytail with layered bangs and controlled burgundy eye makeup suit the disciplined look. A crest cloak clasp and a rolled patrol map replace a weapon.
17. Masquerade Diluc Cosplay

For a masquerade, the mask should frame the face rather than hide it. A long black tailcoat, burgundy brocade vest, ivory ruffled shirt, slim trousers and polished ankle boots are the outfit. Silver embroidery and red crystal buttons dress the coat. I'd pick a black half-mask with a subtle flame pattern and dark red edge, and tie it with ribbon instead of elastic, which digs into the wig. The visible makeup can stay refined: sculpted brows and smoky burgundy eyes. A red ribbon sash and a sealed invitation finish it.
18. Steampunk Diluc Cosplay

Steampunk adds hardware to his formal base. A burgundy waistcoat under a fitted black frock coat, dark trousers and tall lace-up boots set it up. Bronze buckles, gear buttons and narrow straps go across the torso. Every strap and gear adds weight, so I spread them evenly on both sides; a coat loaded on one shoulder hangs crooked in every photo. Goggles sit above the forehead, clear of the bangs. Gloves with foam panels, a pocket watch, a rolled map and a small lantern are the props. Warm matte contour and dark brows keep his face recognisable.
19. Cyberpunk Diluc Cosplay

A cyberpunk Diluc trades tailoring for techwear but keeps the colours. A fitted black jacket with angular red panels, charcoal mock-neck, slim utility trousers and black platform sneakers are the base. Reflective silver strips and battery-powered red piping along the jacket bring in light; I sew the battery pack into an inside pocket so it doesn't drag the jacket open. A high ponytail sharpens the outline. Graphic burgundy liner and a small silver accent at one temple are enough on the face. Leave out the tangle of cables; a few clean lines look better.
20. Vampire Diluc Cosplay

A vampire Diluc can be gothic without blood or fangs. A long black velvet coat, deep red waistcoat, ivory high-collar shirt, fitted trousers and knee-high boots carry the look. Velvet has a nap, so when I cut it I lay every piece facing the same direction; mixed pieces come out in two different shades. A burgundy cape lining and silver chains at the collar add the night-creature mood. Pale matte skin, defined cheekbones and a muted berry lip suit it. An LED candle lantern is a safe prop for a family event.
21. Royal Prince Diluc Cosplay

The royal prince version is all about structure. A black military coat with a burgundy sash, ivory high-collar shirt, fitted black trousers and riding boots are the base. Gold cord, red gem buttons and slim epaulets give the formal finish. I stiffen epaulets with a layer of heavy fusible interfacing or thin foam so they don't droop off the shoulder. A smooth low ponytail with a gold clasp keeps the head tidy. Carry a small decorative crown rather than wearing it, which keeps the hair unmessed, plus a sealed royal document.
22. Academy Student Diluc Cosplay

The academy student Diluc comes together from uniform-style pieces you can wear again. A black blazer with red piping, white high-collar shirt, burgundy sweater vest, tailored trousers and lace-up shoes are the base. A silver crest patch and a slim black tie finish the uniform. Iron-on patches peel off a wool blend, so I add a few stitches around the edge. Slightly tousled bangs soften the formal wig. Tuck the gloves into a blazer pocket for a more believable student, and carry old books and a feather pen.
23. Professor Diluc Cosplay

For an older cosplayer, the professor is a practical, distinguished choice. A long charcoal coat, burgundy waistcoat, cream turtleneck, tailored trousers and leather-look boots form the outfit. Thin silver spectacles and a flame chain across the vest suggest a scholar. Keep the wig controlled and low, with tidy face-framing layers. A hardbound book, lecture notes and a pointer that's clearly a classroom tool make the props. Some events are strict about anything that looks like a weapon, and a pointer avoids that question.
24. Gothic Diluc Cosplay

Gothic Diluc is about tailoring and texture, not fright. A floor-length black coat over a burgundy brocade vest, black high-collar shirt, slim trousers and buckled platform boots form the base. Silver chains, red gem clasps and pointed shoulder panels from flexible foam add the edge. Floor-length coats pick up everything on the floor, so I hem mine to just clear the boot heel. A voluminous waved ponytail and smoky burgundy eyes with neutral lips keep it refined. Lace-trim gloves and a dark book or LED lantern finish it.
25. Punk Diluc Cosplay

Punk Diluc is the easiest to build from thrift-store finds. A cropped black jacket over a red-and-black plaid shirt, fitted black jeans and combat boots give you the outfit. Silver chains, flame patches, foam studs and a burgundy belt add the attitude. I'd stitch on the patches rather than iron them, because a denim jacket flexes at the shoulders and iron-on glue lets go. A high ponytail with textured bangs gives extra movement. Smudged brown-red liner suits him better than heavy black. A red light stick makes the elemental prop.
26. Victorian Diluc Cosplay

His long-coat shape fits the Victorian era almost perfectly. A black frock coat, deep red waistcoat, ivory pleated shirt, fitted trousers and lace-up boots are the pieces. A dark cravat with a red gem pin is the focal point; I tie a cravat around a soft stand collar so it doesn't slip down by lunchtime. Silver buttons line the coat. A smooth ponytail with curled ends keeps it period. A pocket watch, a folded newspaper and a small lantern with a red LED finish the scene.
27. Festival Diluc Cosplay

The festival version is lighter and built for walking. A black wrap top with red edging, dark trousers, a burgundy waist sash and flat boots are the base. A short shoulder cape with gold flame embroidery and small tassels adds detail. Machine embroidery on a light fabric puckers without a stabiliser behind it, so I always back the area first. A half-up ponytail keeps hair out of your face while it still moves. Fingerless gloves, a small crossbody pouch and an LED paper-style lantern make it practical for an outdoor parade.
28. Maid Diluc Cosplay

Maid Diluc is a fan favourite joke, and it works best played completely straight. A long-sleeve black uniform with a knee-length skirt or wide trousers, burgundy piping, a white apron and sturdy ankle boots form the outfit. Silver buttons, a high collar and a small flame emblem tie it back to him. A simple white headband is better than an oversized headpiece. Keep his stern face: straight brows and burgundy shadow. That contrast is the joke. A folded cloth and a tray with berry juice complete it.
29. Casual Winter Diluc Cosplay

This one doubles as a real winter outfit. A black wool coat over a burgundy cable-knit sweater, charcoal trousers and insulated boots carry the palette. A dark red scarf and leather-look belt pull it together. If your own hair is long and red, wear it in a loose low ponytail; otherwise use the wig. Everyday makeup with brown liner and muted burgundy shadow is plenty. A scarf pin shaped like a flame and a messenger bag are useful extras, and a travel mug with something warm is the most practical prop in the list.
30. Black And Red Diluc Cosplay

Strip Diluc down to two colours and you get this graphic version. A long black coat with crimson lapels over a red mock-neck, slim black trousers and knee-high boots form the outfit. I'd use silver clasps sparingly, because each extra metal piece pulls attention from the red and black. A vivid red wig in a full low ponytail with layered bangs is non-negotiable. A sharp sweep of burgundy liner sets the face. A red gem belt ornament and an internally lit flame prop finish it, and the whole thing is far quicker to sew than the game-accurate coat.
Sewing His Coat Trim So It Doesn't Lift
The red piping and edging are what make a plain black coat into Diluc's, and they are also the first things to come loose on most builds. My approach depends on how permanent you want the costume to be.
- For a coat you'll keep as a costume, sew corded piping into the seams. It follows curves and stays put no matter how much you move.
- For a borrowed or thrifted coat you want back, use double-fold bias tape held with fabric glue tested on a scrap, plus a few hand stitches at each corner.
- Ease bias tape around curves rather than stretching it; stretched trim pulls the coat edge into a wave.
- Press every trimmed edge with a pressing cloth. Polyester trim can melt or go shiny under a bare iron.
- Skip hot glue for any trim. It cracks the moment the fabric bends, and it lets go in cold weather.
Faux fur is the other fiddly part. Cut it from the back with a craft knife, slicing only the backing, so the pile doesn't shower everywhere, then shake it outside. Attaching it with snaps means the fur comes off before the coat goes into the wash.
Which Diluc Gets Made This Weekend
If you've never sewn a character coat before, start with the budget thrifted trench or the closet version and spend your effort on the wig. Once those basics feel easy, the classic or Red Dead of Night builds are a natural next project. Any of the casual, royal, gothic, seasonal or futuristic takes lets you play with the same palette and silhouette. Choose breathable fabric for heat, layers for cold and foam rather than metal for armour. Most of all, wear the wig, shoes and makeup for a full afternoon at home first, so nothing surprises you on the day.
