Madame X (Madame Pierre Gautreau) John Singer Sargent (1856-1925)

The picture has something of this: woman, portrait, people, wear, fashion, girl, model, dress, glamour, nude, retro, jewelry, sexy, indoors, dark, veil.
Perhaps it’s a painting of a woman in a black dress sitting at a table with her hand on her hip and her right hand on the side of the table.
