I don't know much about Before Crisis, I've never actually played the game, but what I do know is that everyone seems to like to enter Aerith's church through the roof. X__X With the cosplay itself, things were pretty easy, the shirt doesn't have the design like KH2, or at least that's what I have seen from fan art, I personally don't know if it was meant to have it or not. But anyways, it made from a quick shirt, and the skirt was simple too, I think this is the easiest cosplay I have ever done. XDD
