Winterhalter, Franz-Xaver – Victoria Ière, reine de Grande Bretagne Château de Versailles

The picture has something of this: veil, woman, portrait, dress, wear, princess, fashion, people, model, wedding, girl, queen, fantasy, bride, costume, fashionable.
Perhaps it’s a painting of a woman in a white dress with a blue sash around her neck and a flower in her left hand, with a cloudy sky in the background.
