Pauline Sandor, Princess Metternich Franz Xavier Winterhalter (1805-1873)

The picture has something of this: fashion, veil, woman, dress, bride, model, wedding, portrait, beautiful, glamour, dancing, girl, elegant, people, dancer, sexy, wear.
Perhaps it’s a painting of a woman in a white dress with a veil on her head and a bouquet of flowers in her hand in front of her left hand.
