Mrs. Charles Deering (Marion Denison Whipple) John Singer Sargent (1856-1925)

The picture has something of this: people, portrait, woman, wig, man, wear, Renaissance, costume, dress, engraving, bonnet, veil, sash, victorian, opera.
Perhaps it’s a painting of a woman in a red dress sitting in a chair with her hands on her knees and her right hand resting on the arm of the chair.
