Roberto Cavalli's black fine-knit gown is a stunning example of the designer's high-octane flair. Heavy beaded embellishments weigh this floor-skimming piece down, while a dramatic leather-lace, open back adds extra drama and allure. Lined only where you need it, a flash of bronzed skin is a must at high-profile events.
