Aquazzura's foray into PVC has granted us several chic options for optical-illusion footwear. The label's Optic 50 pumps blend retro and contemporary elements, featuring a chunky stacked heel and a rounded toe. Black leather paneling, including a slim slingback strap, is connected by transparent polyvinyl chloride for modernist finish. We like how ours look with miniskirts, tapping into '60s sensibilities.
