Don't Miss:

Heidi Klum, Taylor Momsen, and Hannah Simone were among the many stars who came out to celebrate the reveal of Donatella Versace’s two new collections for Versus Versace Wednesday night at the Lexington Avenue Armory in New York City. The event stood out for showcasing both London designer J.W. Anderson’s one-off capsule collection for the brand, as well as a revamped archival line for Versus Versace. Combining both music and fashion, the models showed off the looks in groups as musical acts—including Grimes, Angel Haze and Dead Sara—performed throughout. “The launch of Versus Versace brought together everything that I love: fashion, music, DJs, young people and their amazing energy,” Donatella said. “This mix of music and fashion captures the essence of Versus Versace, a label for a new global tribe.” Shop the Versus Versace line now at versusversace.com and J.W. Anderson’s capsule collection come June 15. Plus, see more of last night’s parties by clicking the photo above.

As soon as the red carpet rolled up following the 85th Academy Awards at the Dolby Theatre, Hollywood’s brightest stars hit the party circuit for the all-night festivities! Adele (in Jenny Packham) was all smiles at the Governors Ball, the official after-party held just five floors up from the Oscars stage, posing with the golden statue she nabbed for Best Original Song for “Skyfall.” (“Watch the dress!,” she kindly told guests who kept stepping on her train.) Across town, two annual soirees continued their must-see appeal: Vanity Fair’s epic annual bash heated up with Jennifer Aniston, who posed with legendary designer Valentino Garavani, and Elton John’s 21st annual viewing party, which included guests like Heidi Klum (in Julien MacDonald), also raised money for the Elton John AIDS Foundation. “I love that Elton gets all these people out every year, and he makes a fun night into a very important night,” Klum told InStyle.com. “He’s raised more than $300 million dollars since 1992, and people show up!”
