We changed our concept a little. Our focus shifted from changing clothes to promoting events. So the primary functionality for the user is not to try some clothes on but to get information about events. So instead of just displaying clothes projected on the user we will display some event data and display clothes fitting the event. So for example a football game is promoted and the user gets to wear a matching jersey. A nice-to-have functionality is to manipulate the background so that the user stands right in front of the stadium.
