Paul-Esprit-Charles de Boulogne (1758–1838), Le comte de Nogent, son of the intendant des Finances Francois-Hubert Drouais (1727-1775)

The picture has something of this: people, child, wear, portrait, baby, woman, dress, costume, veil, god, kimono, crown, girl, son.
Perhaps it’s a portrait of a young boy in a pink and white dress with a rose in his right hand and a pot of flowers in his left hand.
