It likes to have the jacket open. I would just specify in the prompt that you'd like it closed if you so wish. However, with the jacket closed, sometimes the vest is the wrong color.
It also seems to just straight up ignore the proper shoe coloration. I'm not sure how to fix this.
Trained on Illustrious, but it seems to work well with the other models I've tried. Does not work on DIT models because I am dumb and didn't think to make them compatible.
