EXCLUSIVE AT NET-A-PORTER.COM. Aquazzura has teamed up with a coterie of fine jewelers for Resort '19 - these slingbacks have been designed in collaboration with Ana Khouri, who's best known for artistic and sculptural pieces. They've been made in Italy from black satin and topped with sparkling crystals at the pointy toes. The key to making the kitten heel height feel fresh? Style them with bold prints or bright tailoring.
