A lot of the fun of New York Fashion Week happens before anyone even walks down a runway, which is why the sister designers of William Okpo, who we profiled in the magazine last year, invited us to the casting call for their upcoming fall fashion show. Picking the perfect girls to rock your looks isn't easy—good casting can make or break a show—so the Okpo sisters (Lizzy Okpo is pictured above in the maroon beanie) tried piece upon piece of their forthcoming collection on a bevy of beautiful models who all came in hoping to be chosen. Check out our behind-the-scenes pictures, below, and check back here Friday morning to see our full coverage of Okpo's new fall collection and to find out if your favorite models were chosen.
