Portrait of Madame X

Painting by John Singer Sargent

Madame X or Portrait of Madame X is a portrait painting by John Singer Sargent of a young socialite, Virginie Amélie Avegno Gautreau, wife of the French banker Pierre Gautreau. Madame X was painted not as a commission, but at the request of Sargent. It is a study in opposition. Sargent shows a woman posing in a black satin dress with jeweled straps, a dress that reveals and hides at the same time. The portrait is characterized by the pale flesh tone of the subject contrasted against a dark-colored dress and background.
