This 5-piece cosplay costume set is designed for fans of the character Xingnai One Song, featuring a coordinated school uniform aesthetic with rock-inspired edge. The ensemble includes a gray blazer-style outerwear with structured shoulders, a crisp white collared shirt, a black pleated skirt with vibrant blue trim hem, a red-and-white striped necktie, and black thigh-high leg warmers with white band details. The outfit weighs only 0.49kg, making it lightweight and comfortable for extended wear at conventions or performances. The blazer has subtle lapel detailing and likely includes functional pockets; the shirt is standard-fit with button-front closure; the skirt features fine pleats for movement and volume; the tie adds a classic academic touch with bold contrast stripes; and the leg warmers provide both visual flair and practical coverage. Ideal for anime/manga cosplay events, music performances, or themed photoshoots, this set balances authenticity with wearable comfort. Fabric appears to be polyester-cotton blend for durability and wrinkle resistance, suitable for indoor and mild outdoor use. The color palette—Gray, White, Black, Blue, Red—is cohesive and visually striking under stage lighting.
