New clothes/style/fashion. :)?

So, I'm getting new clothes. I already know where to buy them from. Abercrombie kids,Hollister,and Aero. Which is the cheapest? Also I would like to know where they sell vintage jewelry. I know they sell cute jewelry at Etsy.com. Also i like things from fredflare.com too. Random/cute things like that. Thx! (Btw i'm an 11 year old girl going into 6th grade *i didn't get left back! My birthday is November 29 and i started school in maryland. The dumb school rule*) Thx!
