I want to reinvent my style over summer; any ideas?

You can go to beauty schools for very inexpensive new hair styles, color, ect. As far as clothing take print of pictures of the style you like, then hit up the second hand stores, you can find great deals, and most of it is brand name stuff. try the Goodwills, Salvations Army's You can get shirt's for $5 or less. And don't for get the Dollor general or Family Dollar. No on will know it's not a brand name unless you tell them. I do it alll the time, and I keep my self looking fashionable!! Good Luck on your transformation!!
