Okarun Cosplay
Dandadan's awkward occult nerd has two cosplay paths: the normal school uniform with bowl cut wig and glasses, or the Turbo Granny transformation with white flared hair, jaw mask, and flame-tail coat. This template covers both as an upgrade path, starting with normal form and layering on the turbo pieces. The jaw mask and bowl cut wig are the make-or-break details. 7 components, 14 materials, ~4 weeks, $70-220.

Build guide
The bowl cut wig will make or break this cosplay. I don't care how clean your gakuran looks or how perfectly you painted the jaw mask teeth. If that wig doesn't have the right mushroom roundness, you're just a guy in a school uniform. I got back from Anime NYC last week and counted maybe fifteen Okaruns on Saturday alone. The ones that read from across the dealer hall all had one thing in common: the wig shape was right.
Buy a pre-styled Okarun wig if you can find one. They're showing up on Arda and a few Etsy sellers now, and they'll get you about 80% there. You still need a flat iron on low (around 160C) to curve the ends inward section by section, and you'll trim the nape taper yourself. Don't buy a generic short brown wig and think you'll cut it into shape. I tried that with a $12 wig from the Amazon basics tier and it looked like a helmet. The fiber was too thick, the cap had no root volume, and the whole thing sat wrong. Wasted afternoon.
Non-negotiable.
The normal form is the cheap path. A black gakuran set runs $25-40, silver round metal-frame glasses are $10, the wig is about $25. You're looking at $70-100 total for normal Okarun, and you can put it together in a weekend if the wig cooperates.
The turbo form upgrade is where the budget climbs. The jaw mask is 3mm EVA foam, contact adhesive, black and white spray paint. Total materials for the mask run about $27. There's a free template on YouTube (the one by the creator who uses both foam and cardboard options, you'll find it). Cut the pieces, glue with contact adhesive, shape to your jaw while the foam is still warm and pliable. Paint the base black, then the teeth white with black recesses between them. Weather the teeth a little so they don't look like they came out of a package. The whole mask takes an afternoon, but most people skip this part: test the fit with your wig on. The jaw mask sits differently depending on wig volume, and if you shaped it bare-headed you'll be adjusting all day at the con.
The white turbo wig is the hardest piece in the entire build. Style upward in sections with Got2b Glued, building layers of volume. Some builders hide wire frames inside to hold the flame sweep shape, and honestly I'd recommend it. Let it set overnight on a stand. Plan to re-style between con days because gravity always wins. The tailcoat needs craft wire through the flame tail hems so they hold their swept shape instead of hanging limp.
Red cosplay contacts and the face stripe makeup finish the turbo look. Order contacts early, cosplay lens retailers take 2-3 weeks to ship. For the stripes, use a flat brush with dark cream-based face paint (not liquid liner, it bleeds). Set with translucent powder and setting spray. Practice at least twice before con day.
Full build for both versions sits around $150-220 over about 4 weeks. I'd start with normal form, wear it once, then layer the turbo pieces on for the next con. Some cosplayers bring both wigs and swap mid-day, which is the move if you can manage the bag space. Pack the jaw mask in something rigid. Foam crushes in backpacks and you won't have time to reshape it in a convention bathroom.
