This is a high-detail cosplay costume set inspired by the character Bai Shihan from the Chinese visual novel and music project 'World Plan' (世界计划), created for their 5th Anniversary Thank You Event. The ensemble features a structured white military-style jacket with vibrant cyan blue lapels, epaulets, and trim, accented with gold-tone buttons, piping, and decorative insignia. A layered waist design includes a striped black-and-white belt, chain embellishments, and a rose pendant. The matching flared white trousers have side panels with subtle star motifs and gradient holographic detailing. The full set includes coordinated accessories: a detachable shoulder strap, left/right hand covers (white glove + black fingerless glove), neck collar, headwear bow, right/left waist accessories (ribbons & badges), leg straps, and a waist seal. Designed for stage performance and fan events, the outfit balances theatrical elegance with modern idol aesthetics. Fabric appears to be lightweight polyester blend for mobility and durability during performances. Ideal for cosplay conventions, live concerts, or themed photoshoots—perfect for fans of Project Sekai/World Plan and J-pop idol culture.
