Mrs. Augustus Allusen (Osma Mary Dorothy Stanley) John Singer Sargent (1856-1925)

The picture has something of this: woman, people, wear, dress, portrait, fashion, costume, music, theater, model, veil, performance, jewelry, glamour, fashionable.
Perhaps it’s a painting of a woman in a red dress sitting in a chair with her hands in her pockets and her right hand on her hippoid.
