Selena Gomez's Style?

I Absolutely love Selena's style because we have a lot in common and it's just really cool. The problem is I think I'm a little too young to where her style. First, I am 11 years old in 6th grade and I am not going to walk around school waring high heels. So the question is........ how do I wear Selena Gomez's style and at the same time dressing my age? Can someone please help!
