Virginia Oldoini, Countess of Castiglione Friedrich Von Amerling (1803-1887)

The picture has something of this: people, wear, woman, veil, portrait, princess, dress, queen, reclining, opera, jewelry, seat, monarch, royalty, music.
Perhaps it’s a painting of a woman in a red dress sitting in a chair with a feathered hat on her head and a feathered shawl around her neck.
