Godfried Schalken – Portrait of Francoise van Diemen Liechtenstein Museum (Vienna)

The picture has something of this: people, portrait, woman, dress, wear, model, girl, opera, fashion, jewelry, veil, theater, gown, light, costume, nude.
Perhaps it’s a painting of a woman in a blue dress with a red and white shawl on her lap and her right arm wrapped around her left arm.
