Size M. Very light polyester chiffon. Only worn twice. Comes with 3 detachable bows and waist ties. Can be worn over and under but the elastic under the bust causes a bit of a gap. I recommend steaming or using fashion/toupeé tape to close it up when wearing. It will relax with more wear regardless. I havent worn it very much so its basically new. I used it for my panda dresses and Im leaving panda so its time for it to find a new home.
