If you equip a costume from a costume dummy, everything is fine, right? But, when you have a costume that covers the hands (mostly or entirely), when you make a fist, nothing changes. A lot of times, your fist is just poking out of the glove or whatever, and it's really annoying. But, if there were to be multiple sectors for the hand on the dummy, such as the palm, fingers, index (pointer, ?), and thumb (?), costume dummy gloves would be able to do things like fists, pointing, etc. It would really add to the magic of player made costumes. More explanation is in the drawing below. Feel free to ask me any questions. I understand that my wording can be a little weird at times.
