Since your already very charming I’m sure your won’t need anything like IO. However IShine would probably go a long way for you. 1 spray could prob add an even more amazing vibe to you as it does with my younger sister who is naturally charming.
I’d definitely take a look at A314 if you haven’t and perhaps check out the Instant Gentleman or Instant Jerk. It would be wrong to assume, but I’m guessing you can be both a gentleman and a jerk when you want to be.
