Rosamond Sargent, nee Chambers Allan Ramsay (1713-1784)

The picture has something of this: people, portrait, wear, woman, veil, jewelry, girl, royalty, dress, lid, model, outerwear, son, fashionable.
Perhaps it’s a painting of a woman in a red dress with a white lace on her head and a blue ribbon around her neck and a white bonnet.
