When I first decided to cosplay Kento Nanami, I knew I wanted more than a decent costume — I wanted the quiet precision and tailored professionalism that makes his suit instantly recognizable. Nanami's look is deceptively simple: a three-piece suit, glasses, tie, and that iconic wristband and blunt demeanor. But getting the fit, the materials, and the small props right makes all the difference. Below I share my process, tailoring tips, prop weapon ideas, and makeup hacks so you can bring Nanami to life with confidence. These are tricks I've learned from sewing, pattern-modding, and testing looks at cons and photoshoots for Jujutsukaisen Co (https://www.jujutsukaisen.co.uk).
Choosing the right suit: fabric, cut, and color
Nanami's suit reads like a classic businessman outfit — neutral yet structured. I always start by focusing on three things: fabric weight, lapel shape, and a slightly oversized-but-not-baggy fit.
Fabric: Opt for medium-weight wool blends or high-quality polyester suiting. Wool blends (like 50/50 wool/poly) drape well and photograph better under convention lighting. If you're on a budget, look for suiting from brands like Fabricland or online retailers like Mood Fabrics. A matte finish is best; avoid shiny blends that read too formal for Nanami.Color: Nanami's suit is a muted taupe/gray-brown. I mixed swatches from several stores until I found a tone that matched reference art. If you have to choose between too-gray and too-tan, go slightly darker — shadows and photos will flatten light colors.Cut: Nanami's blazer is single-breasted with a structured shoulder and a moderate waist suppression. You want a tailored silhouette but allow a little room in the chest for movement. If buying off-the-rack, choose a jacket slightly larger in the shoulders and take it to a tailor for nipping in at the sides.Tailoring tips I swear by
I’m not a master tailor, but I’ve learned how small alterations change a cosplay from “nice” to “authentic.”
Adjust the sleeve length: Nanami's sleeves hit just at the wrist bone, showing a bit of shirt cuff. If your jacket sleeves are too long, have them shortened — and hem the inside lining cleanly so your movement doesn't reveal raw edges.Raise the jacket button stance: Nanami’s jacket buttons a little higher than some modern suits. If your jacket buttons low, a tailor can move the button and reinforce the buttonhole. This creates that stiffer, older-businessman vibe.Get a proper vest: A fitted vest is crucial. If you can, choose a vest with a slightly low V to allow the tie knot to sit neatly. You can also add subtle shoulder pads to the jacket and vest for that controlled profile — I used lightweight foam pads and stitched them in.Pant taper and length: Tailor the pants to be straight to slightly tapered. Breaks are minimal — aim for a single, slight break above the shoe. Hem too short and it looks off; too long and it swamps the clean lines.Shirt, tie, and those tiny details
Details sell Nanami. I always wear a crisp white dress shirt with a medium spread collar and a faintly textured fabric so it doesn't photograph flat.
Tie choice: Nanami's tie is a muted navy or deep slate with a simple stripe pattern, depending on the scene. A wool tie or grenadine weave gives texture and avoids an overly shiny silk look. I often use ties from brands like Charles Tyrwhitt or Beckett Simonon for quality without insane cost.Wristband and watch: The band on his left wrist is an important silhouette element. You can craft one from leather or wide elastic wrapped in fabric to match references. A classic silver or gold dress watch finishes the look; I prefer a slim leather-strap watch that doesn’t distract from the band.Props: blunt-force realism without danger
Nanami’s most notable prop is the blunt, pocket-holstered "wiring" he uses in fights (and sometimes a blunt cane-like prop in interpretations). Safety is non-negotiable at cons, so here are safe, realistic options I use:
Foam-reinforced brass knuckle-style prop: Use EVA foam and Worbla to create a rigid, lightweight piece that looks metallic when painted. Seal with Plasti Dip, prime, and paint with metallic acrylics. This feels solid but is con-safe.Collapsible baton lookalike: If you want the silhouette, use a lightweight PVC pipe core wrapped in foam and fabric. Keep it under 1m and marked per con rules. I used a telescoping plastic baton from a costume shop and wrapped it with faux leather for texture.Holster and pocket props: For Nanami’s pocket items, sew a simple interior pocket holster into the jacket lining so items stay in place while moving. This avoids awkward bulges and keeps the clean front line.Makeup and hair hacks for Nanami's stoic face
Nanami's look is minimal but specific: tired eyes, a permanent frown, and a tidy center-parted hairstyle. Makeup can make a huge difference for photos.
Complexion: Keep the base matte. Use a medium-coverage foundation and set with translucent powder. I prefer the L’Oréal Infallible mattifying powders for long convention days.Under-eye shading: Nanami has subtle under-eye shadows. Use a cool-toned taupe eyeshadow lightly under the lower lash (stick to soft layers — less is more). Add a touch of very thin contour beneath the cheekbones to sharpen the jawline.Eyes: If you wear contact lenses, a slightly darker brown adds intensity. Use a brown eyeliner to tightline the upper lash only; avoid heavy liner. Finish with a matte eyeshadow in the crease to create that permanent concern line.Brows: Keep them clean and slightly angled. Use a brow pencil a shade darker than your natural color, brushing them into position with clear gel for a polished look.Hair: Nanami's hair is neat and parted. If your hair is shorter, a wig is easiest. Use a high-quality synthetic wig and style with low-heat tools or products like Got2b Glued for firm hold. Use a dab of hair wax to define the center part and keep stray hairs down.Maintenance and transport tips for conventions
I've learned the hard way that how you pack and touch up makes or breaks a full-day cosplay.
Carry a mini sewing kit: Include a few extra buttons, a small pair of scissors, and safety pins.Wrinkle prevention: Roll the suit in a garment tube or use a suit carrier. If wrinkles happen, a portable steamer (I recommend the Conair handheld) is a lifesaver.Makeup touch-ups: Blotting papers and a pressed powder compact keep shine at bay. Bring a small brush for recontouring if you plan on multiple shoots. | Item | Why it matters |
| Medium-weight wool suit | Authentic drape and professional look |
| Fitted vest | Key to Nanami’s silhouette |
| Wool/grenadine tie | Texture prevents unwanted shine |
| EVA foam props | Safe and realistic |
| Matte foundation & powder | Long-wear, photo-friendly skin |
Cosplaying Nanami is all about restraint — careful tailoring, subtle makeup, and props that read correct from a distance while staying con-safe.
