Elizabeth Olsen

Although we love taking in the latest runway trends and spotting which famous faces are sitting front row, we are most intrigued by what happens after the shows are over. From Sarah Jessica Parker to Zoe Saldana to Chrissy Teigen to Leigh Lezark, we've spotted a slew of fashionable stars working hard, and playing harder at some of the most exclusive and well-dressed soirees. As New York Fashion Week wraps today, join us in taking a look back at the most fabulous moments captured outside the tents and after hours.

Are you ready for more red-carpet fun? Across the pond, the Elle Style Awards are taking over London town as we speak. And some of our favorite starlets, including Kate Hudson, Chloë Moretz, and Elizabeth Olsen, are there decked out to celebrate. Kate stole the show in her red strapless Stella McCartney gown (how stunning are the lace insets?), Chloë looked perfectly mod in a black-and-white striped dress, also by Stella, while Elizabeth chose an edgier ensemble, including an on-trend leather-sleeved jacket. But they're not the only famous faces who stepped out for the festivities. Step inside to see who else was in attendance.

Elizabeth Olsen, Rashida Jones, and Carey Mulligan treated themselves to a night out in NYC yesterday to celebrate the new Prabal Gurung collection for Target. Decked out in items from Prabal's line, they mingled with a crowd that included Analeigh Tipton, Olivia Thirlby, and the night's entertainment, Ne-Yo. They convened at Manhattan's Pier 57 for a carnival-themed evening full of carousel rides, a Tilt-A-Whirl, and various games and food trucks. The girls had a chance to shop the collection before it arrives in stores and online Feb. 10.

We were on the red carpet at the bash, and had a chance to catch up with Rashida, Elizabeth, and Prabal himself. Elizabeth was excited about Prabal's designs, but not about the rides — carnival rides apparently give her anxiety! Rashida, meanwhile, gushed about her friend Prabal. Stay tuned for more from the stars later today on POPSUGAR Rush.

Dakota Fanning and Elizabeth Olsen continued celebrating their Sundance Film Festival movie Very Good Girls at Fresh's celebratory "Fresh Faces of Sundance" brunch Rock and Reilly's on Wednesday. We stopped by to chat with the two young actresses about working with director Naomi Foner, mother to Jake and Maggie Gyllenhaal. Naomi's son-in-law, Peter Sarsgaard, also has a role in the film, which is just one example of how connected the family is. Dakota spoke about working with Naomi, saying, "I mean, you meet Naomi, and she's like instant maternal love. . . . If you meet Naomi, you meet Ramona, and you meet Jake, and you meet Maggie, and you meet Peter. They are such a connected family — they're very open, warm, loving people." This motherly nature also helped Dakota feel more comfortable with the role, which is a more revealing and risqué part than she's taken on before. Elizabeth and Dakota also shared that they have the same circle of friends and signed on for Very Good Girls simultaneously after chatting about it at a "bonfire in a friend's backyard."

Jake Gyllenhaal stepped out to support mom Naomi Foner, the screenwriter behind Very Good Girls, at the film's Sundance Film Festival premiere last night. He was joined by brother-in-law Peter Sarsgaard, who's married to Maggie Gyllenhaal and also stars in the picture. It was an extra busy night for Peter, since he also debuted Lovelace with Amanda Seyfried. Very Good Girls leading lady Dakota Fanning attended the screening at the Eccles Center theater and later on linked up with her and Peter's costar Elizabeth Olsen at an afterparty. Jake made the rounds with his pal Jenny Lewis. He looked good while doing so — Jake has a new look, with slicked-back hair, for a new project. He's been in Georgia making Prisoners with Hugh Jackman.

Marie Claire magazine gathered a group of starlets together last night for a special Hollywood Dinner held at Fig & Olive in LA. The magazine's editor in chief, Anne Fulenwider, held court over a meal that brought out Zoe Saldana, Elizabeth Olsen, and Lea Michele. Mad Men's Jessica Paré also made the rounds with Magic Mike leading ladies, Cody Horn and Olivia Munn. Leslie Mann, who has This Is 40 heading to theaters Dec. 21, donned a colorful Monique Lhuillier dress to make the rounds. Zoe also upped the fashion ante in Bottega Veneta, and Lea wore Maria Lucia Hohan. It seems a good evening was had, as Lea later tweeted, "Amazing night tonight at the Marie Claire magazine party!!"
