Julia Neilson-Terry (1868–1957) as Drusilla John Collier (1850-1934)

The picture has something of this: wear, people, dress, woman, opera, portrait, music, dancing, theater, curtain, stage, jewelry, dancer, costume, fashion, performance, veil.
Perhaps it’s a painting of a woman in a pink dress standing in front of a red curtain with her hand on her hip and her right.
