The Empress Maria Alexandrovna Franz Xavier Winterhalter (1805-1873)

The picture has something of this: portrait, woman, fashion, veil, people, dress, wear, model, retro, girl, glamour, hair, elegant, lace, queen, fantasy, jewelry.
Perhaps it’s a painting of a woman in a white dress with a veil on her head and a necklace on her neck, sitting in front of a gray background.
