The St. Louis Art Museum showcases Edgar Degas’s study of the art of “high-fashion hats” with “Degas, Impressionism, and the Paris Millinery Trade.” The exhibition contextualizes Degas’s works with that of the impressionists surrounding him and the focus of their attention – the elaborate hats themselves. The works of Édouard Manet, Pierre-Auguste Renoir, Mary Cassatt, and Henri de Toulouse-Lautrec are also featured. The exhibition will be open to the public through May 7.
