Portrait of Madame Dupin (1706-1795) Jean Marc Nattier

The picture has something of this: portrait, people, girl, woman, model, dress, wear, fashion, facial expression, studio, face, baby, brunette, retro, jewelry, actress, child.
Perhaps it’s a painting of a woman in a striped dress with her hair in a bun in the middle of the bun and her left hand in her other hand.
