Tishbeyn, Johann Friedrich August. Portrait of Queen Louise of Prussia Hermitage ~ part 12

The picture has something of this: wear, woman, portrait, people, veil, dress, jewelry, retro, furniture, fashionable, Renaissance, sculpture, museum, antique, fashion.
Perhaps it’s a portrait of a young girl in a white dress with a blue scarf around her neck and her hair in a pony tail, looking to the side.
