Samantha Cameron is an unrepentant multi-tasker, and over the course of her long career in design, beginning at Smythson, she has remained loyal to the concept of versatility. With her label, Cefinn, she specializes in all-day dressing, comprising reliable basics that become the foundation of a woman’s wardrobe. (The name “Cefinn” is based on a loose acronym of “Cameron” and the first initials of the children—Elwen, Florence, Ivan, and Nancy—she has had with David Cameron, the former U.K. prime minister.) Londoners are getting their fix at Cefinn’s pop-up, on King’s Road in Chelsea, although the rest of us will have to be satisfied with e-commerce for now. As Cameron prepares for the holiday-shopping season, she shares her key components to the good life. —Ashley Baker
