Diesel (CLOSED)

Despite all the shops that crowd retail-saturated Fifth Avenue, you definitely won't overlook Diesel's Planet store—its largest location worldwide. Three layers of hand-cut black steel with cast glass intertwine to form a two-story-high Diesel logo plastered on the outside of the 20,000-square-foot space. Three floors showcase the brand's premium denim, along with the Diesel Black Gold collection, handbags, footwear, intimates, leather goods, jewelry, fragrances and more.
