Today's 'It' girl Sienna Miller plays the original 'It' girl Edie Sedgwick in the movie Factory Girl hitting theaters today. After getting the inside scoop from the film's costume designer John Dunn, I learned that Sienna's wardrobe was, not surprisingly, mostly vintage - except a pair of killer Jimmy Choo boots. As you can see, all these wardrobe pieces are still stylish as ever. As much as I would love to go back in time to snag some of these Fab pieces for myself, check out what I did find, ready and available to all of us. Oh and here's a tip: don't forget to wear a pair of sturdy black American Apparel jersey hot shorts, $12, if you dare wear Edie's signature black tights look. Stay tuned for a how-to on getting Edie/Sienna's beauty look from this movie!
