Portrait of Miss Elizabeth Beresford half length John Hoppner (1758-1810)

The picture has something of this: people, woman, sword, portrait, lid, veil, wear, girl, dress, weapon, magic, bonnet, vintage, retro, captivation.
Perhaps it’s a painting of a woman wearing a white dress and a black hat with feathers on top of her head, with a cloudy sky in the background.
