I did not care for this game, because the graphics were not that good. I have no clue how to get the secret medal, but I can at least give you guys some advice. Just putting on random clothes and playing the game is NOT going to give you the medal. I think it's okay to say in a review that not to do to get a secret medal, right? I also felt there could have been more music. It just seemed to stop short.
I tried putting on all of the clothes at one time and nothing happened. I thought maybe that was some secret. I guess I'm just so more used to playing dressup games that have hot naked women in them that I did not like this. Try to put in a lot more detail with some shading. I just didn't find it fun.
