We kept a close eye on Calvin Klein's leading ladies on Thursday. They always seem to be the ones who explode right after walking the show. But gone from Calvin's runway were past-season regulars Toni Garrn, Karlie Kloss, and Taryn Davidson. Instead, Garrn picked up steam elsewhere, opening for two iconic American designers: Isaac Mizrahi and Tommy Hilfiger. Ali Stephens and Anabela Belikova (who was Vera Wang's first face) held onto their spots at Calvin, but otherwise, mostly all of the models were as fresh as they come. Just take a look at Monika Jagaciak from Poland, who at the age of 15 did the honors of opening and closing the biggest show of the day. Opening for Calvin makes a new model rise to top-model status in the blink of an eye. So it's no question that Monika wins Thursday.
