Zenitsu Agatsuma
~5wZenitsu Agatsuma: the yellow-haori Thunder Breathing swordsman from Demon Slayer. This build covers the gradient urokomon haori, the Demon Slayer Corps gakuran uniform jacket, hakama pants, kyahan leg wraps, and the iconic yellow-to-orange ombre wig. The haori is the make-or-break piece; the triangle print needs sublimation or stenciling. 6 components, 13 materials, ~5 weeks, $100-260.
Maomao
~6wMaomao's palace maid look from The Apothecary Diaries is a layered hanfu build: a muted teal-green inner robe with a crossover yi collar visible at the chest, a darker outer robe layered over it, and her signature dark hair pulled into side braids with bun ornaments. The make-or-break details are keeping the inner collar visible through the outer layer and getting the wig buns to hold through a full con day. This is an intermediate sewing build that rewards anyone who can follow a hanfu pattern, with some wig work and light prop making for character accuracy. Includes 7 components, 13 materials with cost estimates, an 11-step build plan, and a realistic 6-week, $110 to $280 budget.

This is an advanced build mixing garment construction, foam shaping, LED work, and heavy wig management. The make-or-break detail is purple color matching across fabric, paint, and wig. Includes 7 components, 15 materials, a 14-step plan, and a realistic 8-week, $250 to $550 budget.
Doctor Doom
~7wMarvel's greatest villain in his iconic green cloak and metal mask: a full armor build with a custom EVA foam mask, sculpted chest and shoulder plates, structured green hood, and gold gauntlets. This is an advanced project spanning foam shaping, armor attachment systems, and precision painting. 6 components, 14 materials, ~7 weeks, $180-420 budget.
