I understand you concern about showing up on day shaved after wearing the piece. But, there is nothing in your head shape that makes me think sly would not look good on you. So all you need to do is make the transition. I also suggest you add some facial hair. It may hep you make the transition.Since you have only been wearing the piece for 6 months, most people likely already know it is fake if they knew you before. So the transition may be easier than you think it is going to be. Most of us that have shaved found out that the transition was not nearly as bad as we expected, almost a non-event other than a few comments.
