Fashion Week's It Girls

Leighton Meester

Gossip Girl

scene-stealer Leighton Meester got her fashion on this season, attending everything from the Calvin Klein 40th Anniversary party to the Prada film premiere. At Julie Haus, Meester wore a bright chiffon dress from the designer (right), then kept up the theme for DVF in saffron ruffles (far left). Later in the week, the fashionista hosted a Kira Plastinina party in a menswear-inspired look (center) from the young Russian designer.

Nicole Richie

Super stylish Nicole Richie show-hopped in leg-baring outfits accessorized with the same pair of strappy velvet Pierre Hardy sandals. Richie wore a cobalt and black DKNY ensemble (center) for the line's 20th anniversary show and then used a plain white tank as a base for her Day 4 jaunt from Proenza Schouler (right) to Marc Jacobs (far left).

Emma Roberts

Nancy Drew

leading lady Emma Roberts showed a sophisticated grasp of style in a needlepoint-emblazoned dress from Ruffian (right, at the Intermix party), a sweet Charlotte Ronson ensemble (center) for the designer's show and a pumpkin-hued tunic over jeans (far left) at the Kira Plastinina party.

Becki Newton

Ugly Betty

beauty Becki Newton is clearly as style-obsessed as her character-making the scene at the Intermix anniversary party in Alexander Wang (far left), the Dolce & Gabbana book signing (right) and the Marc Jacobs after-party (center). At the latter two events, the petite star showed off her shape in fashion-forward numbers from her hosts' collections.

Zoe Saldana

Star Trek

star Zoe Saldana got a leg up on Fashion Week in stem-baring styles from New York's finest designers. The actress wore a ruffled sapphire dress (far left) to Lela Rose, then swung by the Diane von Furstenberg show in a mini-tiered frock (center). At the Dolce & Gabbana book signing, Saldana kept her legs in focus in baggy Bermudas and a tailored vest.

Molly Sims

Las Vegas

star Molly Sims had a winning formula for fashion week: drop-dead dress paired with a cute clutch. Sims hit the Julie Haus show in a bright yellow number from the designer (far left), added a Tod's clutch to her La Perla dress for a Saks Fifth Avenue affair (center) and then accented her Fashion Rocks frock with a shell-shaped silver bag (right).

Lindsay Price

Small-screen stunner Lindsay Price played the fashion game in shape-hugging frocks from all her favorite designers. At Calvin Klein's 40th anniversary party, she honored the designer with a simple sheath (far left), donned a floral Verrier number for the label's Bryant Park presentation (center) and chose a little black dress for the Saks Fifth Avenue kick off party (right).

Jamie-Lynn Sigler

Sopranos

beauty Jamie-Lynn Sigler is a Fashion Week regular, with the wardrobe to prove it. She chose an understated charcoal dress for the Intermix anniversary event (far left) and an embellished BCBG shift for the label's Bryant Park show (right). And for Julie Haus (center), Sigler choose a delicious turquoise frock from the designer: "I like the fabrics she uses, they're very light and flattering."

Joy Bryant

Welcome Home, Roscoe Jenkins

star Joy Bryant saw the shows with super-stylist Rachel Zoe at her side. The duo chose a graphic-print look for the La Perla presentation (far left), followed by subtle sheen for the Calvin Klein party (center). Finally, for the Herve Leger show (right), Bryant donned a leggy look from the line, courtesy of designer Max Azria.

Malin Akerman

Funny girl Malin Akerman is getting her fashion education at the Spring 2009 shows. "I'm just getting familiar with all the new designers out there," the actress told In Style. "Once I've got some clue of what's going on in the fashion world, I'm gonna get out there and buy some great stuff." The former model proved to be hardly clueless-for the Tracy Reese show she slipped into feminine separates (far left), but chose a slinky strapless gown for William Rast. And for a Fashion Week after-dark soiree, Akerman flaunted her form in a leather dress.
