Fabre Francois-Xavier (Montpellier 1766-1837) – Marie-Louise Joubert (78x61 cm) 1787 J. Paul Getty Museum

The picture has something of this: people, portrait, woman, girl, dress, music, beautiful, wear, model, veil, fashion, hair, sit, indoors.
Perhaps it’s a portrait of a woman with a wreath of flowers in her hair, in a purple dress with a yellow sash around her neck and a tree in the background.
