I think that you are perfect the way that you are. I wouldn’t change a thing for anybody. That said, I will try and answer the question.

You didn’t mention how you dress. If you’re talking about your perception to strangers, you might want to consider how you dress. That would be somebody else’s first impression of you. If you determine that this is causing people to look at you a certain way then I would pick somebody that you respect (and that other people respect) and try an take a page from their style. That doesn’t mean copy them or completely ditch your own style, but maybe look at similarities or differences and assess from there.

You keep doing you.
