If you weren't at a fashion party last night, well, you missed out on all the fun. With New York Fashion Week kicking off today, every stylish guy and gal in the city seemed to be toasting, speechifying, air-kissing and posing for pictures at a slew of fashion fetes last night to inaugurate the big week ahead.

Du Jour, the latest glossy magazine to hit newsstands, feted its debut issue with a party hosted by cover star Christy Turlington and photographer Bruce Weber. Held at Capitale, the party drew the likes of Russell Simmons, Amar'e Stoudemire, Hoda Kotb and model Hilary Rhoda.

New York's revamped The Cut, which officially debuted August 13, also threw itself a launch party on the rooftop of the NoMad Hotel, attended by Nigel Barker, Coco Rocha, Lindsay Ellingson and Yigal Azrouel.

Farther uptown, shoe designer Brian Atwood -- recently reprimanded for his overly sexy shoe ads -- threw a party celebrating the opening of his new Madison Avenue store, attended by pals Rachel Zoe, Michelle Trachtenberg, Heidi Klum, Ryan Lochte and Candice Swanepoel (star of the aforementioned ads).

There were also ceremonies honoring some of fashion's greatest: the Fashion Institute of Technology presented Oscar de la Renta with the 2012 Couture Council Award for Artistry at a luncheon earlier in the day (Sarah Jessica Parker and Anna Wintour were by his side) and the 9th Annual Style Awards crowned Carolina Herrera the Designer Of The Year that evening at Lincoln Center (Katie Holmes did the honors).

And that doesn't even include SPIN and Refinery29's party across the river in Brooklyn, the launch of the latest fashion tome, “Antonio Lopez: Fashion, Art, Sex and Disco” (Lopez was a friend of Karl Largerfeld) and the splashy red carpet premiere of "Boardwalk Empire" which drew the Hollywood crowd.

It was hard to be in multiple places at once, but the most seasoned partygoers managed to hit several events each: Iman and Rachel Roy, for example, showed their faces at both the Style Awards and Brian Atwood's fete and Kim Kardashian wowed in a dramatic cutout dress at both the Brian Atwood store and Du Jour's launch.

As for us? We headed to Williamsburg for Refinery29's bash and stayed put.

Check out last night's party snaps... and just envision the hangovers everyone's nursing today. Happy first day of Fashion Week, y'all!
