At 89,000 square feet, this location is the biggest Uniqlo in the world (but there are also branches in SoHo and near Macy's). Shoppers can scoop up staples such as sweaters, skinny jeans, and button-down shirts in a rainbow of colors. Don't miss the limited edition collaborations with big name designers and stylists. The Heattech clothing range is always a big hit. Weekday mornings are the best time to avoid long lines for the dressing rooms.
