Queen Victoria (1819-1901) Franz Xavier Winterhalter (1805-1873)

The picture has something of this: dress, people, woman, wear, veil, portrait, wedding, princess, model, fashion, Renaissance, opera, bride, girl, queen, costume.
Perhaps it’s a painting of a woman in a white dress with a blue sash around her neck and a flower in her hair, standing in front of a curtain.
