This courage of conviction allows such friends of the designer as Caroline Issa and Brazilian princess Paola Orléans e Bragança and other fans—like, say, Gwyneth Paltrow—to stand tall in her designs. (The five-inch pumps she collaborated on with Manolo Blahnik also help).

Casasola has a Central Saint Martins degree and design work at Lanvin on her résumé, but she says she learned the most from her seamstress grandmother, who never left the house in anything but a maxi-length. The lesson, she says: “Luxury is simplicity.”

The cousin had a point. Consider Casasola’s spring/ summer 2014 lineup, which, inspired by the work of Brazilian constructivist master Lygia Clark, explores the duality of discipline and sensuality:

There is something decidedly not of this century about the evening dresses—and they are almost all evening dresses, with a few soigné jumpsuits and pencil skirts in the mix—that she crafts from unembellished satins, cadys, and organzas, with hems cropped just above the ankle. “A lot of people think it makes you look shorter,” says Casasola of her preferred silhouette. “But it’s the other way around.”
