Portrait of Countess Maria Theresia Bucquoi Élisabeth Louise Vigée Le Brun (1755-1842)

The picture has something of this: woman, people, portrait, veil, dress, girl, wear, saint, Renaissance, model, fashion, princess, baroque, cape.
Perhaps it’s a painting of a woman wearing a red dress and a white headdress sitting in a wooded area, with a waterfall in the distance behind her.
