This is the Little Black Dress on steroids! The harness top attach the leash and go. The fabric is black taffeta on top and the taffeta skirt is cut into hundreds of strips for a full skirt that moves this way and that. Then added a spray of hundreds of AB crystals to the harness top that pick up the color of whatever light is near. Its beyond beautiful. It is truly spectacular.For sizes XXL and XXXL please send measurements for lower neck and chest since big breeds vary in body type. We will make the harness to your measurements.
