If I have the money Kohl's, Goodman's, Rue 21, Target -I live one block away.
Like you Alex Marie, I get most of my jeans from Goodwill, most of my brand name jeans are from there.
I have found Daisy Fuentes, Sarah Jessica Parker, Vera Wang as well as other high end labels at Goodwill, you pay a little more then $2-$3 but far less then new.
