Who am i? who do ppl think i am?

Sometimes i wonder what i look like in other people's eyes. I don't even know how old i look in people's eyes... here in beijing i seem to confuse some people... i look like a school girl, but no school girl here my age dresses like me...  lol... anyway... i'm sort of sure that the first impression i give ppl is not very good, smth that says unapproachable... really wonder what they think later... not that i care though... i don't give a thing about what ppl think about me, but i'm pretty curious to know...
