When we kick off New York Fashion Week this Thursday, we're ushering in much more than just the Fall '13 collections. While Fashion Week's function is, of course, an opportunity for our favorite designers and upcoming talent to showcase their latest looks, celebrity fashion and street fashion have become just as much a part of the action. Street style outside the tents is arguably a show unto itself with the personal stylings of the industry crowd proving just as noteworthy. We also can't deny the power of the celebrity draw - from Jessica Alba, Kate Bosworth, and more of our favorites, you never know who will be popping up front row (and what they'll be wearing). And if we turn our attention back to the runways, it's the catwalk that forecasts the clothing we can look forward to wearing the following season (and it's never short of awe-inspiring to see what talent like Michael Kors will deliver). Obviously, it's no easy task to pick apart our favorite aspects of the fashion calendar - so we're turning it over to you. Which part of Fashion Week are you most excited to see?
