Baron Joseph-Pierre Vialetes de Mortarieu Jean Auguste Dominique Ingres (1780-1867)

The picture has something of this: people, portrait, wear, menswear, man, neckwear, jacket, dinner jacket, cravat, outerwear, facial expression, event, wedding, bow tie, outfit, retro.
Perhaps it’s a painting of a man in a black suit with a white shirt and a flower in his lapel and a blue sky with clouds in the background.
