Madame Edouard Pailleron (study) John Singer Sargent (1856-1925)

The picture has something of this: people, wear, man, portrait, two, woman, retro, mammal, artistic, blood, side view, vintage, facial hair.
Perhaps it’s a painting of a woman in a black dress and a red hat sitting on a bench in front of a grassy field with a tree in the background.
