Colin Hanks assumes a distinguished look outside the El Rey's era-appropriate marquee for A Night on The Town with Mad Men. Hanks traded the on-screen clerical clothes of Father Gill for a sleek tux at the event, which was hosted by Chivas Regal. Cast members from the series took the stage to sing for a sold-out crowd.

Mad Men trio Bryan Batt, Christina Hendricks and Robert Morse take a break from cigarettes and office politics to enjoy the show's Night on the Town. While the air was smoke-free, plenty of the sponsor's scotch was on hand to warm things up, Sterling Cooper-style.

Alison Brie sports a fancy neck-protecter with a beaded, flouncy frock that would definitely throw Trudy Campbell, her no-nonsense Mad Men alter-ego, into a tizzy. Brie strutted her stuff in honor of the show's revue-style event in Los Angeles.

The lucious Penelope Cruz strides into a screening of Vicky Cristina Barcelona in London's West End, with flaps of material swishing along with her. She may be one of the world's most seductive stars, but even Cruz needs to mind the lampshade-style attire in public.

Rosario Dawson keeps it elegant in a green silk drop-waist dress. The actress, whose upcoming slate of movies includes our personal fave, Wonder Woman, took some time out from her copious amount of work to take in some art at the opening of Vanity Fair Portraits: Photographs 1913-2008 in L.A.

Christina Ricci also stepped out to take in some visual culture at the Whitney's Art Gala in Manhattan. She boosted the posh-factor up a few notches in a sultry silk dress with some kind of embroidery that, unfortunately, again sets off the lampshade-meets-upholstery alarm.

Elizabeth Banks and Seth Rogen spiff up for the Hollywood premiere of their new film, Zack & Miri Make A Porno. When reporters at the movie's press day asked Rogen about his newly svelte figure, he explained that it wasn't making the porn-within-a-film that led to his weight loss, but his preparation for Green Hornet. And Banks? She's beautiful, but the dress is a code-red on the you-know-what index.

Traci Lords and writer-director Kevin Smith pause for a photo at the afterparty for his latest opus, Zack And Miri. Lords, who began her career as a porn star, appears in the new film as one of the hired help, so to speak. While her career has taken her into mainstream television and film for several decades, our office computer still won't let us on her website to tell you more.

Kate Hudson and Liv Tyler share a laugh at the reopening of Burberry's
Beverly Hills store. Hudson went wild with a mustardy fall frock, while Liv got back to her rocker roots with a hip tee and oversized jacket. Some of us only wear Burberry to swim (to quote Jay-Z), but hip-hop conventions don't seem to faze two of Hollywood's gilded children.

Keira Knightley proves, yet again, that she's a stunner in red-carpet finery... or the most mundane of urban winter wear. The actress keeps the caffeine close on location for Last Night in New York.

Kathy Griffin accessorizes a bedazzled, taffeta-skirted dress (which speaks for itself) with two Emmys at the Best in Drag Show in L.A. The D-List mastermind hosted the benefit for Aid for AIDS, an organization that offers finanical assistance to L.A. County residents with HIV and AIDS who live below the poverty line.

Brooke Shields got into the spirit of an autumn night with her children, Rowan and Grier Henchy. The three of them attended the Children Affected by AIDS Foundation Dream Halloween at Roseland, in perhaps the best evening garb seen so far this season.
