Jean Patou, “the most elegant man in Europe”, revolutionized women's fashion. His fashion house, founded in 1914, left a lasting mark on the era with silhouettes that were both elegant and relaxed. An enlightened aesthete, Jean Patou designed evening dresses with simple lines, created a monogram with his initials, and marketed the first sportswear made for the city. The designer dressed women like Louise Brooks, Josephine Baker, tennis champion Suzanne Lenglen and Mistinguett... After his death in 1936, Marc Bohan, Karl Lagerfeld, Jean Paul Gaultier and Christian Lacroix all worked for the Parisian label before its long dormancy. Today, Guillaume Henry is opening a new chapter in Patou's history, dedicated to women's ready-to-wear, inspired by couture.
