The bodice is lined with cotton and has a front button closure. The dress has an attached center back peplum belt that has a large bow and long streamers. The skirt has a back train and is fully lined with cotton. The dress has age related flaws including several age marks from ½ inch to 2 inch on the bodice, skirt and peplum belt.
