Christina Augusta von Fersen (1754-1846), g. Löwenhielm * Pehr Hilleström (1732-1816)

The picture has something of this: people, veil, woman, wear, portrait, sculpture, music, dress, outfit, church, indoors, Renaissance, castle, lid.
Perhaps it’s a painting of a woman in a red and white dress standing in a doorway with her arms in the air and her right hand in her other hand.
