This is a high-detail cosplay/performance costume set inspired by the Chinese idol group 'World Plan (Tian Ma Si)' for their 5th Anniversary Gratitude Concert. The ensemble features a structured white long-sleeve shirt with gold piping, layered under a cropped white jacket with gold epaulets and holographic silver iridescent panels. A matching yellow satin vest with black-and-white striped waistband adds contrast, while white flared trousers with gold cuffs and star embroidery complete the look. Accessories include a left chest ornament (medal-style brooch), side waist accessory (gold branch-like chain), bow tie, gloves (black/white pair), arm ring, leg band, and detachable waist seal skirt. The outfit emphasizes theatrical flair with metallic finishes, precise tailoring, and coordinated accessories—ideal for stage performances, fan events, or themed cosplay. Fabric appears to be polyester blend for durability and sheen; lightweight at 0.94kg. Not a commercial fashion brand item but a licensed merchandise costume set.
