Prada’s model casting is always a hot topic of discussion in the Fashion Spot forums. Whether for the runway or an ad campaign, an appearance for the brand can effectively launch the career of a new model. So each season, Prada parades a bevy of quirkily beautiful new girls down the runway, sometimes even signing them to exclusive deals, effectively limiting the number of other runways they can walk down for other brands. They also have the ability to pull in a number of established models who no longer frequent the catwalks. Check out the slideshow below to see the women Prada effectively called dibs on with exclusives and special requests for Fall 2013.
