L’Ultimo Sguardo allo Specchio Giovanni Boldini (1842-1931)

The picture has something of this: dress, costume, woman, fantasy, people, mystery, castle, veil, baroque, decoration, sculpture, culture, Gothic, statue, masquerade, traditional, Venetian.
Perhaps it’s a painting of a woman in a blue and white dress standing in a room with a mirror and a table with a vase of flowers on it.
