Portrait of a Lady in a White Dress aka Miss Edith Newbold William Merritt Chase (1849-1916)

The picture has something of this: people, wear, portrait, veil, music, woman, dress, man, musician, crown, wig, theater, costume, vintage.
Perhaps it’s a painting of a woman in a white dress with a black ribbon around her neck and a flower in her hair and a black collar.
