Emmeline Mary Elizabeth Welby-Gregory (1867–1955) John Collier (1850-1934)

The picture has something of this: portrait, people, wear, woman, jewelry, girl, model, fashion, brunette, necklace, facial expression, dress, veil, fashionable, jacket, music, hairdo.
Perhaps it’s a close up of a painting of a woman in a red dress with a white ruffle on her collar and a green wall in the background.
