Comtesse de Ceres Élisabeth Louise Vigée Le Brun (1755-1842)

The picture has something of this: woman, people, lid, portrait, wear, veil, costume, fashion, girl, performance, theater, opera, model, dress, stage, queen, music, actress.
Perhaps it’s a painting of a woman wearing a blue hat with a feather on top of her head and writing on a piece of paper with a pen in her hand.
