From Alibaba: When you take say a pair of shorts off the rack, a mirror suggests pairing them with a matching blouse, shoes, and a bag from existing inventory. The suggestions become personalized, based on what you’ve previously bought on Alibaba. Try them on – Is it too big, or the color not right? Press that on the mirror, and the new item appears on a hanger. Not ready to buy? The app remembers everything you looked at, so you can purchase later.
