We've also assigned different materials to the various parts (buttons, buttonholes, borders, stripes and so on) to customize the outfit even most and we've also created some MATs to hide parts and change the look of the outfit. These MATs only make some parts transparent so you should "reset" the texture every time you want to hide a different part and this also allows you to use more than one MAT at the same time.
