Lucy Liu steps out of her Dirty Sexy attire and into something a little more comfortable for the launch party of Alberta Ferretti's US flagship store in L.A. With the Italian designer setting up shop on local turf, American women will soon benefit from sartorial vision that one critic called "sublime creativity" and a "commitment to inventive eveningwear."

January Jones loses the girdle and opts for a swishy, sparkly dress much more in line with the Italian lifestyle at Ferretti's party. Jones, whose Mad Men character is known in part for her striking dresses, has a frock or two of her own to wow us with when the TV cameras stop rolling.

Selma Blair goes geometric at the Hellboy II: The Golden Army DVD and Blu-ray release party at Element in Hollywood. The actress' mod style may not be frilly, but, as any superhero's girlfriend knows, it takes tough clothes to save the world.

Do Hollywood hotshots really shop at H&M? With her trendy '80s-inspired ensemble and red carpet attendance, Mena Suvari would have us think so.

We never thought we'd say it, but Kelly Osbourne is one glamorous vision of a rocker on the red carpet. The elder of the Ozzy spawn was polished and sophisticated with a belted dress and rouged cheeks at the Shaun White Snowboarding Video Game launch party. Admittedly, we can't picture her snowboarding (virtually or otherwise) but thumbs up, Kelly, for rising to the occasion.

Mad Men's Elisabeth Moss shows off a little décolletage at the MoMa Film Benefit Gala honoring Aussie filmmaker Baz Luhrmann in New York.

Maggie Gyllenhaal and a very bearded Peter Sarsgaard get gussied up, old-school style, for a night at the museum. The Dark Knight heroine and her husband donned their finery (with Mrs. G looking especially fine, might we add) for the MoMa film benefit gala in New York.

Just in case we forgot that bondage is all the rage in the fashion world this fall, Rachel Weisz gave a subtle hint at the Baz Luhrmann party in New York. We're not ones to judge sacrifices for fashion, we but we do hope there's a massive coat checked under her name at the museum's entrance.

It looks like a mutual love-fest for America Ferrera and Hillary Clinton, who are beaming at the 2008 Glamour Women of the Year Awards at Carnegie Hall. "I'm very grateful to Glamour, because they really liked my pantsuits and that was really an honor!" the radiant senator, who was among the honorees of the evening, said in her acceptance speech.

Former Vampire Slayer Sarah Michelle Gellar strikes a pose with a matching Fergie at the Glamour Awards. Our only question? If Fergie's ode to the glam life got any rotation at the event.

Rose McGowan, no stranger to pushing the fashion envelope, sports some sexy specs for Matthew Rolston's book party. The veteran fashion photog was debuting his latest tome, beautyLIGHT, in Beverly Hills.

A ravishing Salma Hayek attends the 2008 Hollywood Domino Tournament to Benefit The Art of Elysium in New York. The Ugly Betty star not only pulled off wearing an accessory on her forehead, but was also supporting an organization that brings artists and critically ill children together to enrich each other's lives.

Heroes' multifaceted, ass-kicking mom proves she can also outshine a star-studded event. While puffy tufts of fabric near the face are always questionable, the super-powered Ali Larter almost glows beside her extra fabric.

Lindsay Price's on-screen alter-ego is all about high couture, but the Lipstick Jungle star knows how to step out in real life, too. The curvy actress drapes herself in luscious lamé at The Art of Elysium benefit.

Jenny McCarthy gives her son Evan Asher a squeeze at a benefit for her autism research organization, Generation Rescue.

Alicia Keys hits the right notes of sexy, hip and sophisticated in a flowing, strapless number at the World Music Awards in Monte Carlo. The dazzling musician went on to win for Best R&B Artist in the World.

Solange Knowles may be breathing new life into her busy career, but there's still room for a fashion misstep now and then. Her flouncy dress is high on flirtation, but low on judgment when it comes to texture across the bodice.
