Portrait of Grand Duke Alexander as a child Dmitry Levitsky (Levitzky) (1735-1822)

The picture has something of this: portrait, people, woman, wear, necklace, music, brunette, skirt, jacket, facial expression, girl, musician, man, jewelry, choker, model.
Perhaps it’s a close up of a painting of a person wearing a brown jacket and a blue dress with a brown collar and a brown leather jacket around his neck.
