Nattier Jean-Marc (Paris 1685-1766) – Constance-Gabriel-Madeleine Bonnier de la Mosson as Diana (129x96 cm) 1742 J. Paul Getty Museum

The picture has something of this: people, woman, portrait, wear, girl, reclining, man, nude, veil, model, two, underwater, recreation, fashion, facial expression, dress.
Perhaps it’s a painting of a woman in a white dress with a leopard on her shoulder and a red and white dress.
