How do you become the "it" girl of your school?

Please nothing mean! I'm already pretty popular but I just get kinda nervous around cool ppl. I have the right looks, I live in a rich community so I have a Dooney and Bourke bag, a Juicy Couture bag, a Guess bag and a Kathy bag. I have really cute and nice clothes and stuff so all i need is just some tips to become the Alpha (like in the Clique books). I'm very creative. GIVE ME SOME TIPS!
