Pastel woman period late XVIII - early nineteenth

Pastel woman period late XVIII - early nineteenth. Young woman with a vaporous hairstyle, English and ostrich feathers, with a blue headband holding the hair. Sweet and dreamy look. We can guess the cotton chiffon dress, topped with a linon fichu, very fashionable under marie-antoinette. Gilded wooden frame, trace of gilding wear, on the bottom; old bubble glass; label of the framer legible on the back (see photo).
