Appearing on magazine covers and in advertising campaigns, the Delevingne sisters—Chloe, Poppy, and Cara, in birth order—have been fixtures in the fashion pantheon for more than a decade. For even longer they have graced the London social scene. Born to aristocrats on both sides—their mother, Pandora Delevingne, is an elegant beauty, and their father, Charles Hamar Delevingne, is a dapper property developer—the sisters possess not only manners, beauty, and style but an archly British type of iconoclasm and verve. For this, they blame family friend Ned Ryan, an intimate of Princess Margaret’s (their maternal grandmother was her lady-in-waiting), who toasted their arrival into the world by rubbing droplets of champagne on their gums just hours after they were born.

Logging into Zoom from three different locations, the sisters discuss their first joint business project: the launch of a sustainably produced brand of prosecco, aptly named Della Vite, a play on both their surname and the provenance of the grape itself. (Literal translation, “of the vine.”)
