The medium-weight canvas is twill woven; it has been lined. The ground is white, smoothly applied and of thin to moderate thickness. The painting is executed smoothly and fluidly, with transparent layers in the darks and low impasto in the highlights. X-radiographs have revealed slight pentimenti; the neckline of the dress has been moved about one inch to the right and is lower than it first was, the folds of the sleeve above the elbow originally followed more the curve of the arm, and the folds in the green drapery to the left of the sleeve were once more broadly curved. The painting was cleaned and restored by Romney in 1795. The painting is in good condition except for heavy retouching in the darks at lower right over fine traction crackle caused by bitumen. The natural resin varnish has discolored yellow moderately.
