This vibrant, theatrical costume set is designed for the 'World Plan Colorful Stage (Mirror Sound Connection 10th Anniversary)' performance, featuring a coordinated ensemble in elegant turquoise and white. The outfit includes a structured satin-like turquoise vest with ruffled lapels and silver buttons over a voluminous white long-sleeve shirt with gathered cuffs, paired with matching turquoise shorts trimmed in white satin and adorned with a decorative music-note waist sash. Accessories complete the look: a bunny-ear hat, detachable bow tie, waist sash with musical motif, belt, socks, and necktie—all in harmonized turquoise and white. Crafted from lightweight synthetic fabrics for stage mobility and visual impact, the set emphasizes playful elegance with frills, layered textures, and thematic musical details. Ideal for cosplay, idol performances, or themed events, it balances whimsy and sophistication. The M size (0.65kg) ensures comfortable wear during extended performances, while the cohesive design allows for dynamic movement and photogenic appeal under stage lighting.
