Rotari, Pietro – Een jonge vrouw, 1756-1762 Rijksmuseum: part 3

The picture has something of this: portrait, woman, girl, people, model, fashion, nude, studio, wear, glamour, facial expression, dress, hairdo, retro, jewelry, fashionable, face.
Perhaps it’s a painting of a woman in a white dress with a green sash around her neck and a white flower in her hair, looking to the left.
