Ashley Olsen and designer Tommy Hilfiger

Designer Tommy Hilfiger was confident that his latest collection would wow guests like Ashley Olsen. "It's more sophisticated but still young and fun. The silhouettes are all new," Hilfiger said. "In my opinion it's one of the best collections we've ever put out. Although I said that last season too!"

Penn Badgley, Hayden Panettiere, Ed Westwick and Rosario Dawson

The guys of Gossip Girl were also on hand to view Tommy Hilfiger's fall collection. "It's a classic American brand and it has a big presence on our show," said Ed Westwick, who posed with Penn Badgley, Hayden Panettiere and Rosario Dawson backstage.

After showing her support at the presentation of their fall collection earlier in the week, Kirsten Dunst helped Rodarte designers Kate and Laura Mulleavy celebrate the opening of the Quicktake: Rodarte Exhibition at the Cooper-Hewitt Museum.

It was a family affair at the Ralph Lauren show, where the designer's daughter Dylan, son David and David's girlfriend Lauren Bush watched the models walk the runway in pieces from the fall collection.

Brooke Shields, Designer Gilles Mendel and Melissa George

After joining Melissa George to rave about the elegant evening gowns in designer Gilles Mendel's J. Mendel collection, former model Brooke Shields reflected on the hectic pace of Fashion Week. "While there's a little less pressure when you're not in the show, there's still huge pressure when you're sitting in the front row," said Shields. "But I survived!"

Marchesa's Keren Craig and Georgina Chapman

After getting raves about their latest collection from fashion fans like Nicole Richie, Molly Sims and Melissa George, Marchesa co-founders Keren Craig and Georgina Chapman toasted to the launch of Dom Perignon Wedding during a luncheon at the Magic Room inside the LVMH Tower.
