The canvas is twill woven; it has been lined. The ground is white, of moderate thickness. What remains of the original paint in the face and figure is freely applied in thick, opaque layers, blended wet into wet. The sky and background are severely abraded and very heavily overpainted; the sitter's hair and neck are also overpainted. The costume was overpainted c. 1820; this overpaint was removed and the picture restored to its original state in 1872. The coat is badly abraded and has been extensively retouched. The impasto has been flattened during lining. The heavy natural resin varnish has not discolored.
