Pourbus, Frans the Younger – Portrait of Margaret of Savoy, the Duchess of Mantua Hermitage ~ part 10

The picture has something of this: people, veil, wear, woman, portrait, cape, Renaissance, sword, Gothic, fame, dress, lid, costume.
Perhaps it’s a painting of a woman in a dress with a crown on her head, standing in front of a red chair and a blue curtain behind her.
