It does nothing for your personality. Your personality is your personality, whether you're in a tux and surrounded by billowing clouds of some divine attar, or in a tshirt and unwashed.
It is an expression of your personality. I'd say it is an interesting one, but there are better ways to express yourself. For the vast majority of people, you smell good or you don't, and they don't really understand the particulars of what "good" might mean.
