It looks like Natalia Vodianova's stint at Alexander Wang wasn't a one-time appearance. The current face of Givenchy, Yves Saint Laurent, and Stella McCartney hit up Diane Von Furstenberg's runway to open and close. French model David Agbodji closed out the menswear Calvin Klein show. Let's hope that's a sign that he will renew his steamy contract with Calvin Klein for fall, too. Meanwhile, the Jablonskis ruled at Philosophy di Alberta Ferretti: Jacquelyn opening and Constance closing. However, like anyone else, we love a good comeback. And yesterday saw the return of Sigrid Agren. After taking take a brief runway hiatus last season, the delicate gamine came back stronger than ever when she opened for Hervé Léger, and closed Thakoon. Welcome back to the game, Sigrid! See who else opened and closed Sunday's top shows in the slideshow.
