Mrs. Charles Huntington (Jane Hudson Sparkes) John Singer Sargent (1856-1925)

The picture has something of this: people, portrait, wear, music, woman, performance, dress, musician, singer, costume, furniture, facial expression, room, light, girl, man, theater.
Perhaps it’s a painting of a woman in a long black dress with a white collar and white ruffled collar, standing in a dark room with a chair.
