Portrait-of-Madame-Virginie-Gautreau-(Madame-X)

Madame X or Portrait of Madame X is the informal title of a portrait painting by John Singer Sargent of a young socialite named Virginie Amélie Avegno Gautreau, wife of Pierre Gautreau.

The model was an American expatriate who married a French banker, and became notorious in Parisian high society for her beauty and rumored infidelities. She wore lavender powder and prided herself on her appearance.

Madame X was painted not as a commission, but at the request of Sargent.
