If you know fashion, you’re certainly familiar with the French brand Chloé. And you’ve certainly heard of the impressive lineup of talent the house has nurtured: Karl Lagerfeld, Stella McCartney, Phoebe Philo, Gabriela Hearst. A name you may not recognize, however, is that of Chloé’s founder, Gaby Aghion. Born to a wealthy Jewish family in Egypt, raised in comfort, Aghion (née Hanoka) moved to Paris with her husband, a Marxist intellectual and art dealer, in 1945. Seven years later, she set the Parisian fashion scene ablaze, having created a new niche—breezy, witty, fetching dresses for women bored with the stiffness of couture. The Jewish Museum exhibition explores the life and gifts of Aghion as well as the rich history of the brand from its beginning to the present day. The free-spirited elegance of Chloé and its founder are embodied in the 150 garments and never-before-seen documents now on display. —Lucy Horowitz
