John Singer Sargent – Portrait of Mrs. Edward L. Davis and Her Son, Livingston Davis Los Angeles County Museum of Art (LACMA)

The picture has something of this: people, portrait, wear, woman, lid, coat, man, veil, two, dress, fashion, costume, model, girl, outerwear, retro, child.
Perhaps it’s a painting of a man and a woman with a boy in a black dress and a white hat standing next to each other in front of a dark background.
