Philippe-Alexandre-Marie, duc de Wurtemberg Franz Xavier Winterhalter (1805-1873)

The picture has something of this: portrait, woman, fashion, girl, people, model, beautiful, child, dress, wear, hair, studio, sexy, love, pretty, music, young.
Perhaps it’s a portrait of a young boy in a white dress with a beaded necklace sits in front of a painting of a blue sky and white cloud.
