Arlecchino Cosplay
Arlecchino (The Knave) is Genshin Impact's most cosplay-demanding Fatui Harbinger: a layered suit jacket, structured long coat with back chains, multi-color ombre wig, character-specific X-pupil contacts, and a full accessories set that runs 12+ pieces. This is an advanced build for cosplayers who can sew structured garments, handle prop accessories, and plan a full character makeup look. The make-or-break details are the coat's lapel structure and the wig's silver-black-red color work. Includes 8 components, 14 materials with cost estimates, a 12-step build plan, and a realistic 7-week, $180 to $420 budget.

Build guide
My first Arlecchino coat had uninterfaced lapels. I wore it to Sakura-Con in April and by noon they'd flopped open like sad little ears and the entire silhouette was gone. I fixed it for the afternoon slot with safety pins hidden under the front placket, which is not how you want to spend Sakura-Con.
The lapels are the thing that will ruin this build if you get them wrong. Everything else is recoverable. The coat is long enough to hide imperfect hemwork. The wig ships styled. The contacts are their own separate problem (more on that). But the lapels have to hold their shape through a full con day under body heat and three layers of fabric, and the only way that happens is heavyweight sew-in interfacing on the lapel and collar pieces before you ever touch the outer fabric. Not fusible. Sew-in. Fusible interfacing bubbles and separates under heat, and the charcoal suiting this coat wants is dense enough that fusing is inconsistent anyway. I use a firm tailoring canvas from Portland Textile in Portland, Oregon, baste the roll line before I cut, and then press the lapel curve over a tailor's ham about twelve times before it stays. It sounds excessive. It is not excessive.
The fabric question matters too. Arlecchino's coat is deep charcoal, not flat black. I learned this by holding a swatch of black polyester gabardine next to a screenshot of her in-game model under fluorescent lighting in the Joann in Torrance, and the gap was obvious. You want something with a slight sheen and weight, a ponte or wool-blend suiting, closer to dark grey than true black. The color shift is subtle in person but cameras pick it up and the community will pick it up in photos.
Order the wig and contacts the same day you start the coat. The Sweety Crazy Knave Cross contacts ship from Asia and take 2-3 weeks. They're the only contacts that actually read as her X pupils on camera, but I'm not going to pretend you can walk a convention floor in them. One reviewer said they had to hold things close to their face to read and needed help navigating crowds. That tracks with my experience. Wear them for photos, swap to plain dark red contacts for hall wear, and don't argue with yourself about this.
The wig: buy pre-styled from SAKUMETA or OSIAS. The silver-black-red ombre color work is genuinely tedious to DIY (one TikTok creator described the process as 'colour blocking, hairline work, parting, wire strands, and airbrushing') and a quality pre-styled wig runs $45-80, which is less than a weekend of your time. Check the front hairline before you're at the con. It's a known weak point on pre-made Arlecchino wigs and requires a few additional wefts glued in to close the gap.
For the forehead X: face paint only. Red face paint, not lipstick, not eyeshadow. Mark your forehead center first with a white eyeliner pencil, paint the X symmetrically outward, and seal it immediately with setting spray. Without sealing it softens within two or three hours. Practice the X twice before con day, because symmetry on a curved surface is harder than it looks in a mirror.
This is a $180 to $420 build over about 7 weeks. The coat and jacket are the time cost. The accessories (back chains, collar piece, headpiece with feathers) are the budget cost, but they're all sourceable: real jewelry chain for the back, a printed clip for the headpiece, the decorative pieces from Etsy STL sellers. Skip the waist chain on the hall floor. It catches on everything.
Start with the coat. Everything else fits around it.

Pattern Plan
Real sewing patterns for each piece of the Arlecchino costume: the commercial base to start from, a free alternative where one exists, and the exact modifications that turn the base into the character-accurate piece.
Structured long overcoat
Modifications for structured long overcoat: Use the longer view. Taper the silhouette at the waist before flaring below the hip to match Arlecchino's fitted-then-dramatic coat shape. Convert the double-breasted front to a single-breasted closure with hidden snap fasteners under the front placket. Omit the fur collar option and use the plain notched collar. Raise the back vent height by 4-5 inches for dramatic tail movement. Interface collar and lapels with sew-in tailoring canvas, not fusible.
Modifications for structured long overcoat: This coat runs to mid-back (~55 inches back length) which suits the length needed. Remove the gathered two-piece sleeves in favor of a standard one-piece set-in sleeve for a cleaner modern silhouette. Omit the contrasting collar and use self-fabric. Add structured shoulder seams with shoulder pads. Interface all collar and lapel pieces with sew-in canvas only.
Neither commercial pattern matches Arlecchino's coat exactly. The S3177 requires waist shaping modifications; the M8137 requires sleeve simplification. Either is a valid starting point. The key alteration is the same for both: the coat must pull in at the waist and have fully interfaced, sharp-breaking lapels.
Fitted suit jacket and vest
Modifications for fitted suit jacket and vest: Use the stand collar jacket view as the base for Arlecchino's fitted jacket, and the collarblocked vest view for the under-vest. The stand collar already matches her character design. Convert the separating zipper front to button closures on the vest. Interface all lapel and collar pieces with sew-in interfacing; the pattern recommends fusible but sew-in holds better under the overcoat's weight.
Modifications for fitted suit jacket and vest: Use View A (single-breasted). The peaked lapels are a closer match to Arlecchino's jacket lapels than the notched lapels on most men's patterns. Omit shoulder pads or use very thin ones; Arlecchino's jacket has a structured but not heavily padded shoulder. Add a stand-up collar piece from McCall's M5252 or S9191 if you want her raised collar element.
S9191 is the more forgiving base and includes both jacket and vest in one envelope. V8988 gives better lapel shaping but requires more tailoring skill. If you're sewing the overcoat and jacket in the same session, use S9191 for the jacket so you can focus your advanced techniques on the overcoat.
