European clothing giant TopShop ran a little test in a Moscow store recently: hook a Kinect camera up to a mirror and let the ladies try on clothes without having to actually try them on.
It sounds good in theory, and in some instances looks good in theory, but its practical use is limited somewhat by the fact they're at an actual store. With change rooms available, and the clothes actually in their hands. Why see a poorly-fitting virtual representation of an outfit when you can walk ten metres and see what it looks like in the flesh?
Still, it's a neat idea!
