PORTRAIT OF MADAME AIGNAN DE SANLOT Élisabeth Louise Vigée Le Brun (1755-1842)

The picture has something of this: portrait, girl, people, model, woman, fashion, dress, studio, face, lady, princess, beautiful, cute, costume, hair, doll, child.
Perhaps it’s a portrait of a woman in a blue dress with a blue ribbon around her neck and her hair in a bun.
