Wow this is a head turner. The pants fit quite tightly to the knee and then billow out bell-bottom style. They are pull-on and do have stretch. The top is elasticized around the torso and fastens behind the neck with two buttons. It is a swing top that is high-low. Gorgeous lace! Either piece could be worn alone, as well. Runs true to size. Inseam is 29” give or take a bit. I’m wearing the medium and stand 5’4”; I’m barefoot in the pictures. I measure 36/29/38. What a fabulous set.
