The painter Édouard Vuillard (1868-1940) liked to say that he didn't paint portraits in the conventional sense; he painted people in their homes. If commissioned to paint a portrait, he would ask the sitter to make herself comfortable and then follow her around the room with his eyes. At a moment when she seemed at ease, he would begin to sketch. When Vuillard later converted his sketches into a painting, he would stage the room to fit the character of the sitter. In this manner he painted a fashion designer who worked hard and led an orderly life sitting at her desk in front of a grid of bookshelves, and a friend who was fond of luxury and lazy afternoons reclining on a plush divan.
