Countess D´Haussonville Jean Auguste Dominique Ingres (1780-1867)

The picture has something of this: fashion, model, dress, portrait, wear, woman, girl, glamour, people, fashionable, gown, beautiful, veil, hairdo, jewelry, skirt, wedding, haute couture.
Perhaps it’s a painting of a woman in a blue dress with a red flower in her hair sitting in front of a blue table with a mirror on it.
