DAILY COVERAGE! CHECK IN WITH INSTYLE.COM ALL WEEK FOR INSIDE ACCESS TO THE SPRING 2008 FASHION SHOWS AND PARTIES, AND A PEEK AT THE CELEBS IN THE FRONT ROW! 02 of 17 Liev Schreiber and Naomi Watts Theo Wargo/WireImage The view at a 2006 post-show Calvin Klein party was as breathtaking as the clothes on the runway: 360-degree views of the city from the 52nd floor of 7 World Trade Center. Oh, not to mention Drew Barrymore, Natalia Vodianova and Maggie Gyllenhaal, the trio of beauties who hosted the bash on behalf of Calvin Klein creative director Francisco Costa. Other notables included Liev Schreiber, Naomi Watts, Lindsay Lohan, Rachel Zoe, Mischa Barton, Michelle Trachtenberg, Mena Suvari, Maria Menounos, Jaime King and Seann William Scott. 03 of 17 Kelly Ripa Kelly Ripa struck a pose in a sexy frock by Diane von Furstenburg as she helped kick off fall fashion week at the 2007 Red Dress Collection fashion show. The annual event showcased one-of-a-kind red dresses-the symbol for women's awareness about heart disease-modeled by some very familiar faces. Kim Cattrall, Jane Krakowski and Katharine McPhee managed to keep up with real-life mannequins Helena Christensen and Alek Wek on the red-carpeted runway. 04 of 17 Josephine Miller, Sienna Miller Jesse Grant/WireImage Sienna Miller brought along mom Josephine for the Rag & Bone show last February. "They make the best jeans," the actress said while waiting for the action to start. She later joined Cameron Diaz at Tenjune nightclub in the Meatpacking District to congratulate the designers on the successful presentation of their line. Cameron sipped champagne and confessed that she's not a Fashion Week fan, but appreciates the opportunity it "gives designers to showcase their creativity." 05 of 17 Britney Spears Britney Spears caused a commotion when she showed up to preview the fashions at Baby Phat. Before settling into her front-row seat, Britney doffed a conservative blazer to reveal a slinky satin cocktail dress. Spotting a strapless number on the runway, she whispered, "I want that!" Also on hand for the show: Nicky Hilton, Jamie-Lynn Sigler and Alicia Keys. 06 of 17 Rachel Bilson, Rihanna, Joel Madden, Nicole Richie Dimitrios Kambouris/WireImage Rachel Bilson , Rihanna, Joel Madden and Nicole Richie made up a fashionable front rows as they watched the Zac Posen show in the tents at Bryant Park. The designer's collection followed some of the fall 2007 trends seen on the other runways around town, including lots of fur and the color purple. Posen's finale even included some Oscar-worthy dresses. 07 of 17 Sean Combs Marc Andrew Deley/FilmMagic Even when Sean Combs isn't busy debuting a collection from one of his own fashion lines, the rap mogul is a familiar face in the tents at Bryant Park. Still, Combs' mom Janice often outpaces her suave son, hitting the shows-and after-parties-for Baby Phat and Zac Posen at fall fashion week last spring. 08 of 17 Rachel Bilson, Zac Posen Dimitrios Kambouris/WireImage After winging in on the redeye from Los Angeles, Rachel Bilson looked picture perfect backstage at Zac Posen, wearing her best dress by the designer. Bilson also hung out in the swanky W Hotel lounge at the Bryant Park tents before the Badgley Mischka show, where she admitted to being more than a little fashion-obsessed. 09 of 17 Joan Jett, Carmen Electra Gregory Pace/BEImages Though she sat next to legendary rocker Joan Jett in the front row at Anna Sui, Carmen Electra admitted that her accessories were inspired by an icon from another era-Madonna. Before the show, Carmen could be overheard recounting tales of her fun-filled Fashion Week. Electra also brought along her stylist to be sure that she wouldn't forget which pieces she had to have for fall. 10 of 17 Narciso Rodriguez, Jessica Seinfeld, Rachel Weisz and Claire Danes Stephanie Halmos/PMc Narciso Rodriguez , Jessica Seinfeld, Rachel Weisz and Claire Danes partied in style at the Gramercy Park Hotel following the debut of designer's fall line. As cocktail waitresses circulated with champagne, guests grooved to an eclectic soundtrack of lounge disco and ska reggae. 11 of 17 Vanessa Minnillo and Patricia Heaton Marc Andrew Deley/FilmMagic Though the tabloids hinted that MTV's Vanessa Minnillo was shopping for a wedding dress, there was no bridalwear on the catwalk at Monique Lhuillier. Instead, Minnillo and Patricia Heaton watched as the designer debuted a fall line of daywear and red-carpet dresses inspired by the architecture of Frank Gehry. 12 of 17 Amber Valletta, Seth Meyers Gina James/Graylock/Retna Ltd. After a reunion with fellow '90s supermodel Shalom Harlow backstage, Amber Valletta took a front-row seat next to Saturday Night Live funnyman Seth Meyers for the Marc Jacobs fall show. Valletta and Meyers played witness as Harlow strutted her stuff in an unforgettable bordello-red sheath and elbow-length leather gloves. 13 of 17 Lil' Kim, Marc Jacobs Joe Schildhorn/PMc Lil Kim greeted a newly shorn Marc Jacobs at a party held at Eugene to celebrate his new fall collection. Once inside, Kim proceeded directly to a cozy VIP section, where JC Chasez, Pete Wentz and Michelle Rodriguez also settled into the oh-so-trendy animal-print banquettes. 14 of 17 Katharine McPhee, Joss Stone Trevor Kent/INF Goff Katharine McPhee and Joss Stone kept their wits about them as they were swarmed by photographers at the Marc Jacobs show. McPhee, a Fashion Week novice, was the first celebrity to arrive at the New York State Armory building and was soon backed up against a wall by the clamoring press. Stone's hairstylist-who gave the natural brunet her new shade of punk pink-took advantage of his client's popularity, handing out his business cards to reporters. 15 of 17 Alicia Keys Roger Wong/INF Goff With her pin-straight bangs and cinched black trench, Alicia Keys played the part of fashionista to a T outside the tents at Bryant Park before a Tracy Reese show. Keys's entourage was small but effective. Her stylist, Wouri Vice, came along to help scout for future fashions while a burly bodyguard kept photographers at bay. Keys was sorry she couldn't stay for the rest of the week, but said she had to get back to Los Angeles to finish recording her latest album. 16 of 17 Michelle Williams Scott Wintrow/Getty At the Sari Gueron show, a prescient Michelle Williams echoed the air of au naturel that was seen all over the runways at fall fashion week. "It feels like a fun girls' day out," said Williams, who was in good company sitting next to Sonic Youth's Kim Gordon and just down the row from Anna Paquin. Williams's day also included the Phillip Lim show. 17 of 17 Drew Barrymore Theo Wargo/WireImage In 2006, Drew Barrymore co-hosted the Calvin Klein after-party with Maggie Gyllenhaal and Natalia Vodianova. The actress missed the show because of a bad case of food poisoning, but recovered in time to be the hostess with the mostest. DAILY COVERAGE!
