Mrs Charlotta Pilo, not Desmarées Carl Gustaf Pilo (1711-1793)

The picture has something of this: people, portrait, lid, wear, veil, man, woman, scarf, wig, jacket, costume, elderly, face, Renaissance, cravat, facial expression.
Perhaps it’s a close up of a painting of a woman with a red ribbon around her neck and a black dress with a white collar.
