Jump into your roadster, adjust your goggles, and steer toward St. Louis, where the greatest era in car culture is the subject of a spectacular exhibition. Focused on the aesthetic trends of France in the interwar years—1918 to 1939—the show will have you asking yourself: Does high design get any better than this? Fashions by Lanvin, Poiret, Chanel, Patou. Art by Léger, Braque, Mondrian. Textiles, decorative art objects, furniture. It’s all anchored by 12 period cars—curvaceous, gleaming, dream machines from Ettore Bugatti, Delage, Delahaye, Talabot-Lago, and more. “Roaring” is a pilgrimage-worthy show. —Laura Jacobs
