Mademoiselle de Fitz James Ignace-Henri-Jean-Theodore Fantin-Latour (1836-1904)

The picture has something of this: people, portrait, wear, woman, necklace, jewelry, dress, fashion, man, veil, profile, girl, model, retro, outerwear, side view.
Perhaps it’s a close up of a painting of a woman in a pink dress with a gold medal on her neck and a brown necklace on her neckline.
