Mrs. William Russell Cooke John Singer Sargent (1856-1925)

The picture has something of this: people, portrait, wear, queen, costume, woman, dress, retro, veil, royalty, vintage, theater, music, antique, princess, lace.
Perhaps it’s a close up of a painting of a woman wearing a black dress with a white ruffled collar and a beaded necklace on her neckline.
