What is this style? 10 POINTS :)?

Annie Wilson/Shenae Grimes' style on 90210. I'm not talking about Shenae but, Annie Wilson's style. Not season 1 or 2 but season 3, THREEEE. I love her style, where does it look like the stylist's get the character's clothes at, or what would you call this style? Omg, please tell me. I love her style.
