It would be alot of fun to add a new skill set of barbering, that could involve new decorative items like chair and shaving soaps etc, even tho we do have scissors and mirrors and such already, but you could have the skill fails result in crazy hair looks for characters , you could make them have different hair styles and beard designs and colors ..would be a fun skill to do for a change. Combine all these and u would have new character design, new skill set and new decorative items.
