I want to change my style in the new year, what are some cute trends for me?

[beautifulgirlm]

I'm a teen girl, and I'm very slim, and tall. Many clothes won't fit right because of the way I'm built. I have long hair that's sometimes hard-to-manage. I normally need it to be out of my way, but I like wearing it down, too. What are some cute outfits, accessories, and hairstyles for me to try that will be popular in 2011? Could you link to pictures for outfits, and maybe video tutorials for simple hairstyles?

Thanks!
Oh yeah and the outfits can't be like $300 or something because I don't have much money.
