Anne Catherine Le Preudhomme de Chatenoy, Comtesse de Verdun Élisabeth Louise Vigée Le Brun (1755-1842)

The picture has something of this: lid, veil, people, portrait, woman, girl, fashion, wear, fashionable, model, dress, bonnet, festival, costume, cowboy, straw, retro.
Perhaps it’s a painting of a woman in a white dress and a brown hat with a flower on top of her head, wearing a red and white dress.
