Adélaïde Labille-Guiard – Posthumous Portrait of Louise Elisabeth of France, Duchess of Parma, shown with her Son Don Ferdinand, age two, future Duke of Parma Château de Versailles

The picture has something of this: costume, people, woman, veil, theater, wear, theatre, dress, dancer, two, music, fashion, glamour, performance, stage, portrait, actress.
Perhaps it’s a painting of a woman in a black dress and a child in a white.
