Anya Forger
~3wSpy x Family's telepathic kid in the Eden Academy uniform. The build is a black A-line dress with gold scalloped trim, a white Peter Pan collar, a red bow, and a pink wig with horn clips. It looks simple, but the wig quality, horn stability, and trim finish are where beginners hit walls. This template covers 6 components, 10 materials, a 10-step build plan, and a $40 to $120 budget across 3 weeks.
Wonder Woman
~8wThe DCEU Gal Gadot warrior: a sculpted Worbla breastplate over a red corset base, layered leather tasset skirt, gold bracers, knee-high armored greaves, a forehead tiara, and the Lasso of Truth. This is an intermediate-advanced build combining thermoplastic armor shaping with leather work and metallic finishing. Covers 7 components, 12 materials with cost estimates, a 12-step plan across 5 phases, and a realistic 8-week, $180 to $450 budget.
Makima
~4wChainsaw Man's most unsettling devil hunter, built from off-the-rack business formal and one killer wig. No sewing required. The whole look is a white dress shirt, black tie, slim pants, and a knee-length trench coat the kind of sharp office-wear that reads instantly as Makima on the con floor. The pink-red wig with straight bangs is the make-or-break detail, and the yellow ringed circle lenses seal the unnerving effect. 7 components, 9 materials, about 4 weeks, $80 to $220.
Johnny Joestar
~7wSteel Ball Run's Johnny Joestar: a high-fashion jockey-inspired outfit with cream jacket, star-pattern pants, a distinctive white hat with pink horseshoe accents, and blonde spiky hair. The challenge isn't just sewing, it's nailing the runway proportions and SBR's signature makeup style. 6 components, 12 materials, ~6-8 weeks, $150-350.
