Ladies, is it the way i look?

lol didnt know how to word the question but anyways ill try to make this short, but i cant figure this out, im 18 never had a gf or a even girl that just happens to b a friend, an its like when ever i make eye contact with any girl, like lets say im walkin in the mall i just get a dirty look even if i smile im just trying to figure out wats goin on here, is there somthing about the way i look thats doing this, or maybe the way i dress i wear nothing but affliction now an i do have a 3/4 sleeve, be honest like what would you think if i approached you or smiled as i walked by?
