Ла Тур, Морис-Кантен де (Сен-Кантен 1704-1788) – Людовик Французский (1755-1824), граф Прованский и будущий король Людовик XVIII Part 6 Louvre

The picture has something of this: portrait, people, girl, child, baby, face, cute, dress, woman, fashion, studio, costume, love, beautiful, princess, hair, eye.
Perhaps it’s a portrait of a young boy in a pink dress with a star on his chest and a blue sash around his neck, in a blue circle.
