Princesse de Caraman Chimay later Madame Jourdan Giovanni Boldini (1842-1931)

The picture has something of this: portrait, people, woman, wear, model, dress, veil, girl, costume, fashion, recreation, lid, retro, theater, music.
Perhaps it’s a painting of a woman in a long black dress with a stick in her hand and a hat on her head, standing in front of a door.
