Bridget Sutton, 3rd Duchess of Rutland Sir Godfrey Kneller (1646-1723)

The picture has something of this: woman, portrait, people, dress, girl, model, fashion, wear, jewelry, sit, veil, seat, glamour, fashionable, furniture, pants, necklace.
Perhaps it’s a painting of a woman in a white dress sitting in a chair with a blue blanket on her lap and her left hand resting on her knee.
