you should make it so it's possible for an item to change the base sprite of a character. for example, if a helmet that covers the whole head is worn, the hair won't be poking out.

also, i have another suggestion. i haven't yet bought the plugin, so ignore if this is already a feature. you should add like a layering system, for example for stuff like hair and capes. for example, when an item is worn and the character faces the front, the item goes behind everything, but in the sides and back, it is layered above everything else.
