After some significant amount of preseason buzz, Lindsay Wixson hit the runway, opening for United Bamboo, with fellow newcomer Yulia Leontieva closing. French beauty Heloise Guerin did double-duty, opening for Lacoste and closing for ADAM. Sessilee Lopez closed Christian Siriano's show for the second season in a row, and Behati Prinsloo opened. Ohne Titel brought out runway regulars Karlie Kloss and Iris Strubegger to open and close. And at Alexander Wang, rising star Jac closed the collection. Usually, the young designer casts more established faces to open his shows (Natasha, Raquel, Freja), but this week he opted for rookie Mirte Maas. From the rumblings we're hearing, this is just the start of her breakout season. Click ahead to see the rest of Saturday's openers and closers.
