Turns out, you know nothing about Zac Posen. That face you can't help but recognize, and that name that conjures up red carpet moments of celebrities turned swans like Gwyneth Paltrow, Reese Witherspoon and more. But that fairytale story of a designer prodigy whose star burned bright is packed with even more highs and lows than you could imagine.

Last evening, Brooks Brothers and The Cinema Society hosted the premiere of House of Z, a brilliant documentary telling of Posen's epic rise, infamous fall, and celebrated comeback. Fresh in the throes of fashion week, unsurprising still was the crowd which dodged shows and parties for a night at the movies. Anna Wintour, Katie Holmes, Heidi Klum, Kate Upton, Coco Rocha, Domino Kirke, Pat Cleveland and more joined to support their friend.
