Sir Phillip Albert Gustave David Sasson John Singer Sargent (1856-1925)

The picture has something of this: people, portrait, man, wear, side view, music, leader, musician, profile, outfit, facial expression, veil, singer, performance, festival, outerwear.
Perhaps it’s a painting of a man in a black suit and white shirt with his hands on his hips wearing a white shirt and a black jacket with a white collar.
