Madame Errazuriz (also known as The Lady in Black) John Singer Sargent (1856-1925)

The picture has something of this: people, portrait, wear, musician, music, jacket, woman, facial expression, singer, retro, outerwear, jewelry, necklace, movie, brunette, performance.
Perhaps it’s a painting of a woman in a black dress sitting in a chair with a fan in her hand and a smile on her right side of her face.
