GUESS ATHLETIC VINTAGE LOUNGING WEAR This is a 100% cotton pair of lounging pajamas. The set includes shorts with a drawstring and stretch waist and a matching top. Both pieces are stretchy, waffle weave material. The top is labelled medium and the bottoms are labelled large. But I would consider both of these size small petite. Please see and consider the measurements before purchasing to make sure that this will fit you properly. While the waist is only 24 inches, it stretches to 36 inches. The top stretches to 20 inches.
