When a newcomer books an opening or closing slot at Calvin Klein, she instantly becomes a rising star. So look out for more of rookie Josefien Rodermans, the Dutch face who opened and closed for the label — as an exclusive, too! — yesterday (she follows in the footsteps of Toni Garrn and Daphne Groeneveld). Yet we're awarding the daily win to the stunning Kelly Mittendorf, who closed out Marc Jacobs's delightful spring collection. Mittendorf, as you may remember, caused a big preseason buzz with her major breakthrough: Prada's fall 2011 campaign, shot by Steven Meisel. After skipping all the shows earlier in the week, the Phoenix native finally made an appearance at Anna Sui, and then had the honors of closing the biggest — and final — show of New York Fashion Week. See these looks, and more, in the slideshow ahead.
