In this photo taken Wednesday, April 15, 2015, sales manager Alysa Stefani demonstrates the Memory Mirror at the Neiman Marcus store in San Francisco's Union Square. The mirror is outfitted with sensors, setting off motion-triggered changes of clothing. The mirror also doubles as a video camera, capturing a 360 degree view of what an outfit looks like and making side-by-side comparisons. (AP Photo/Eric Risberg)
