A super prep that could either be a middle school prep: AE and Hollister clothing, and also Abercrombie (And Fitch). Or, possibly, a prep-prep. That would include Juicy Couture, Polo, Lacoste, and any designer brand jeans/clothing. Dior is the preferred bag choice. As an added bonus, watch any episode of Laguna Beach/the OC.
Middle School prep: Oh em gee! I am such a middle school prep in these AE jeans. Yours are sooooo five minutes ago.
Uber-Prep: ohmigawd these Dior sunglasses and Lacoste polo were sooooo cheap...less than 600$. Each.
