Comtesse de Cambaceres Adolphe William Bouguereau (1825-1905)

The picture has something of this: dress, veil, woman, bride, people, portrait, fashion, wedding, wear, beautiful, girl, retro, gown, love, jewelry, glamour, model, elegant.
Perhaps it’s a painting of a woman in a white dress with flowers in her hair, sitting on a couch with a black cat in front of a wall.
