Portrait of Charles IX (1550-1574) Francois Clouet (1510-1572)

The picture has something of this: wear, woman, fashion, people, dress, portrait, model, fashionable, veil, jewelry, retro, footwear, outfit, glamour, actress, public show, necklace.
Perhaps it’s a painting of a man in a tuxedo standing in front of a chair with a red drape on the wall behind him and a red curtain behind him.
