Trish... That's all I'm saying. ;P

In this thread you will see pictures of Dante wearing a coat different from his main one. It's a new model which has replaced his main coat, so to speak. So if a coat can be replaced, so can the rest of the model. However, it would be hard work to do so, but it is possible.
