Vanity Fair and Juicy Couture honored 20 years of the mag’s Vanities on Feb. 20 at Siren Studios.

What is a Vanity?

A Vanity is a good-looking up-and-coming actor who graces not the cover but one of the inside pages, and has hopes of going on to being a cover. Appropriately enough, the party that helped kick off Oscar Week began in the Siren elevator, where guests were greeted with a bar so they could imbibe on their way on to the rooftop shindig. There on the walls, bathed in pink mood lighting, hung a few dozen pix of former newbie femme fatales and heartthrobs. Many of them actually appeared in the flesh, including Amy Adams, Jessica Chastain, Rashida Jones, Anna Kendrick, Olivia Munn, Hayden Panettiere, Marley Shelton and Mary Elizabeth Winstead. Along for the ride were Marcia Gay Harden, Jena Malone, Stephen Merchant and Troy Garity.

“I’m just here for the free food and, of course, for the women,” joked Merchant. “But my dream is to get a top-level watch. Please take note, Rolex.”

Not everyone had his eye on the loot. The bash promoted the charity All It Takes, created by Shailene Woodley and her mother, Lori.

“We teach kids through team-building workshops to break down their walls and learn to be more generous with each other. Hopefully, they realize there is no room for judgment,” said the “Descendants” actress, a Vanity turned covergirl.
