Witsen, Willem – Portret van een meisje, 1885-1922 Rijksmuseum: part 3

The picture has something of this: people, portrait, brunette, woman, wear, famous, necklace, popularity, jewelry, talent, jacket, event, facial expression, fame, person, veil.
Perhaps it’s a close up of a painting of a girl with a red bow on her head and a blue shirt with a white collar and a red.
