The fourth internationally held Fashion Rocks fashion show/concert hybrid event just took on South America last weekend. Do we wish had been there? Well. With over 75 models in addition to the designers, and music acts including Diddy, Grace Jones, Mariah Carey, Ja Rule, Estelle, and Ciara... You bet. Any weekend that kicks off on Friday with a charity dinner hosted by Donatella Versace and comes to a close on Sunday night with a Calvin Klein party on a hotel rooftop? Count me in.
