Portrait of Princess Sophia Radzivil Franz Xavier Winterhalter (1805-1873)

The picture has something of this: portrait, woman, girl, model, fashion, fantasy, dress, lady, beautiful, people, magic, fairy, queen, sword, costume, princess, wear.
Perhaps it’s a painting of a woman in a white dress with a blue ribbon around her neck and her hair in a bun with a flower in her hair.
