Portrait of Miss Harriett Anne Seale as Bo-Peep, Standing Full Length, in a Landscape John Hoppner (1758-1810)

The picture has something of this: people, woman, veil, portrait, girl, wear, dress, princess, lid, captivation, child, model, nude.
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.
