NY Fashion Week: Day 1

"All of Julie’s clothes are so fun and sweet," said Gossip Girl's Leighton Meester, here with designer Julie Haus at her Spring 2009 fashion show. "It's all about this dress. I can wear it during the day and feel glamorous, then vamp it up a bit and it’s still sexy and summery for night." The actress had a busy day on Friday, hitting both the Jason Wu and Haus fashion shows, and then made a stylish appearance at Fashion Rocks.

The Las Vegas actress beat the New York City heat in a flowy and feminine Julie Haus dress at the designer's fashion show. Sims-already a Fashion-Week regular-was joined in the front row by Jamie-Lynn Sigler and Gossip Girl's Matthew Settle.

The Manhattan-based actress made a stop at the Generra fashion show before jetting to the Toronto Film Festival for the premiere of her film, Blindness. Her travel-friendly outfit included this plaid Generra dress and slouchy Christian Louboutin boots.

Charlize Theron

played it cool in oversize shades at the Rag & Bone fashion show-the only show she plans to attend this Fashion Week-at Pier 94 in New York. Later that evening the actress gave nod to the design house by wearing a rocker-chic look to Fashion Rocks at Radio City Music Hall.

Forget the no-white-after-Labor-Day rule, Emma Roberts was a beauty in a white satin dress at the Erin Fetherston show at The Promenade in Bryant Park. The actress is only making a quick stop at New York Fashion Week before she heads to the Toronto Film Festival to promote her movie, Lymelife.

"Everything on me is Dolce & Gabbana!" declared Ugly Betty's Becki Newton, who attended a posh fete hosted by the Italian fashion house for Michael Roberts's new photo book, The Good Shepherd. "Lately I've been inspired by the farm-girl, New-England look, so when I saw this blouse I just loved it," she explained, while mingling with the well-heeled guests who gathered at the label's sleek Madison Avenue boutique to toast the book-a series of black-and-white photographs inspired by Dolce & Gabbana's sheepskin-chic Fall 2008 collection.

Actresses Carla Gugino and Malin Akerman also stopped by the Dolce & Gabbana-hosted photo exhibit and book-signing party in New York.

"I’ve been a fan of Max for a long time," said actress Jamie-Lynn Sigler with the designer at his BCBG Max Azria Spring 2009 show in the Bryant Park tents. "I’ve been wearing BCBG since I was 13 years old... I love the classic and feminine style-it's never too over-the-top."

Leighton Meester

posed with designer Jason Wu and actress Allison Miller at the designer's fashion show at Exit Art in New York. "At Jason Wu I saw these really beautiful dresses," Meester said later on in the day at Fashion Rocks. When asked if she saw anything that she wanted for herself, Meester said she had her eye on one dress in particular: "There was this purple, long, jeweled-toned dress that was the most beautiful thing I've ever seen!"

Though designer Nicole Miller showcased colorful and ethnic-print pieces at The Salon in Bryant Park, actresses Melissa George and Entourage'sPerrey Reeves kept their looks on the darker side when they attended the fashion show. The stars were joined by other notable guests including actress Jill Hennessey, author Candace Bushnell and singer Duffy.
