We almost made it through Fashion Week without a model fall. The surprise, when one finally came at Zac Posen, was that it wasn't a newbie who took the plunge, but runway vet Karen Elson — as she was closing the show, no less. Brazilian bombshell Caroline Trentini helped her up, with help from Sean John (as Diddy/Puffy/Sean Combs is now calling himself) who chivalrously stepped onto the runway to extend a hand. Maybe he's a gentleman after all. Elson later came out smiling with Posen for his bow. —Kendall Herbst
