Miss Harriett Anne Seale as Bo-Peep John Hoppner (1758-1810)

The picture has something of this: girl, dress, portrait, people, fashion, fairy, woman, princess, wood, tree, model, wear, child, park, magic, nature, fall.
Perhaps it’s a painting of a young girl in a white dress and hat standing next to a tree in a wooded area with a red ribbon around her neck.
