Perhaps the only thing more exciting than a new, fresh-faced model is a new, fresh-faced model with a posh, aristocratic pedigree. Stella Tennant, a descendant of the famous Mitford sisters, reigned supreme in the 1990s with her mix of hauteur and languid chic. Cara Delevingne followed two decades later, combining rarefied DNA (she’s the granddaughter of Sir Jocelyn Stevens, a member of Princess Margaret’s social circle) and a punky attitude. The latest member to join the ranks is 18-year-old Lady Jean Campbell. The daughter of Colin Robert Vaughan Campbell, a Scottish peer and the Seventh Earl Cawdor, and Isabella Cawdor, a former British Vogue editor, the young Campbell made her fashion debut in 2013, when Mario Testino shot her for Burberry. She has since walked the runway for the brand, been honored as a model of the year at the Scottish Fashion Awards in 2014, and become an unofficial muse to Nicolas Ghesquière: She’s appeared in his shows for Louis Vuitton (below, spring 2016) and currently stars alongside Jaden Smith in the Louis Vuitton Series 4 campaign. All of which might explain why Delevingne has moved on to acting.
