Daisy suggested, in today's product meetup, the idea of having a customized dressing room, perhaps as part of the Lookbook tool.
I think the idea would be that you could create a scene (and eventually buy one on the store) whose sole purpose is to be optionally used in Lookbook. We could use it to customize lighting, for example. Or have custom backdrops that seem appropriate for certain clothing styles. And, of course, for quick photography of store items.
