ritratto della contessa luigia douglas scotti d adda Francesco Hayez (1791-1881)

The picture has something of this: people, portrait, woman, wear, jewelry, girl, model, fashion, actress, dress, profile, side view, veil, facial expression, nude, music, necklace.
Perhaps it’s a painting of a woman in a black dress with her hair in a bun in her hair and wearing a black.
