There is no certain age. Some people like that sort of stuff early, like even 10, or there are people like me (tomboys basically) who couldn' care less about that stuff. And who cares what clothes you wear? Everyone has their own size and therefore shops for different brands, it doesn' matter really. And I am 12, and I have never worn makeup (minus halloween), never had a smart phone, never had a real crush, never shopped for clothes anywhere by wall-mart, and never had to shave my legs. And there is no age where you really have to grow up, maybe expand common sense a little, but not much else than that. And though, for most people, 18 is not the age where that starts, is would be around preteens and 13-14 range I think. But as for people looking older, there isn' much you can do about that, so don' worry about something you are unable In anyway to change.
