Portrait of a Woman, traditionally identified as Margaret Stuart, Lady Hippisley Pompeo Girolamo Batoni (1708-1787)

The picture has something of this: woman, portrait, people, girl, dress, bonnet, wear, model, skirt, fashion, retro, Renaissance, glamour, jacket, lady, costume.
Perhaps it’s a painting of a woman in a blue dress with a white ruffle on her head and a veil.
