Portrait of Marie Gabrielle de Gramont, Duchesse de Caderousse, Elisabeth-Louise Vigée Le Brun
On Google Art Project, also available on Wikimedia Commons. Original is in the Nelson-Atkins Museum of Art.
I think Vigée Le Brun likely “sweetened” her portraits a bit — flattering the sitter — but I’m a complete sucker for it. I just love the way she paints. Look at the soft, painterly edges of the face, hands, forearm and fruit, contrasted with the rough texture and harder edges of the scarf, ribbon and hat.
