From dazzling LCD/LED video displays to rotating mannequins to staircases with color-changing LED lights, Uniqlo’s Manhattan flagship is massive in scope and bold in design.

The three-level, 89,000-sq.-ft. store is the largest Uniqlo outlet in the world. It’s a big store for a company with big ambitions: Uniqlo parent Fast Retailing Co., the world’s fourth-largest apparel retailer, is targeting $50 billion in global sales by 2020.
