This is by far the most convincing virtual dressing room. One of the main reason is that when you bend down, the skirt will follow you and when you open your leg, it makes sure that the skirt follows nicely.
Too bad, Arbuzz uses a guy to demonstrate this dressing room. Anyway, with Kinect, it is able to make out the skeleton structure of the person. So, it can map the clothes and when you move, it follows. Of course, not perfect now, but I guess it is nice to innovation out of Kinect.
