Mrs Flora Macdonald Allan Ramsay (1713-1784)

The picture has something of this: woman, dress, portrait, girl, wear, fashion, people, model, beautiful, costume, skirt, fashionable, brunette, veil, performance, lady, glamour.
Perhaps it’s a painting of a woman in a white dress with a blue cape and a pink ribbon around her neck and a white cat in her left hand.
