While playing through the game I've noticed some items seem to be improperly categorized. Sorry if I'm wrong and any of these items are supposed to be categorized this way.
The Goth Vest, Enchanted Dress, Cocktail Dress, Sissy t-shirt, Pop idol t-shirt are all categorized as underwear, and the chrome chestplate and Nyandroid panties were categorized as headgear.
Anyway, very cool game, and I hope this helps a bit!
