Mrs. William Crowninshield Endicott John Singer Sargent (1856-1925)

The picture has something of this: people, portrait, wear, woman, music, costume, performance, musician, theater, man, opera, veil, singer, lid, concert, dress.
Perhaps it’s a painting of a woman in a black dress sitting in a chair with a white ruffled collar and white lace on the top of her dress.
