Ivory silk brocade with self pattern and polychrome floral sprays, altered c. 1780, probably originally a sacque, carefully pieced with short-sleeve bodice, drawstring neckline, linen lining with laces, trained skirt over petticoat with side ties. B-36, W-32, L 54-59, petticoat W-38, L-38. Purchased from Amy Pleadwell, Boston, 1960, dress originally had a note from a Mrs. Mansfield, pinned to the dress in 1829. It said the dress had been worn by her grandmother at a reception given by Martha Washington at Mount Vernon, not found with dress. (Small holes, two repairs in skirt, some seam separation, very minor spots, train hem some soil) excellent. Together with fine 18th C lace trim and Victorian fancy-dress lace bows removed from dress.
