Fashion Week Stargazing: Day 2 By the second day of New York Fashion Week, the pace was picking up and so was the celebrity wattage. Friday morning started off with a bang at Milk Studios for the Peter Som Spring 2013 runway show. "Girls" cast member Allison Williams, daughter to NBC anchor Brian Williams, was attracting the bulk of the attention, lovely in a burgundy cropped sweater and matching skirt, until the teenage sensation Hailee Steinfeld teetered in on sky-high platform pumps by Brian Atwood. Wearing a green long-sleeved lace dress by Mr. Som, naturally, Ms. Steinfeld was wide-eyed, if not bushy-tailed. "You have to be a morning person sometimes," she said. Jason Wu's show was in the afternoon, with most of the guests arriving fashionably late (that is, to say, with still plenty of waiting time to go). Not Emily Mortimer, a fan of the designer since she wore a dress of his for the premiere of "Leonie." The "Newsroom" actress, in a coral sheath with jeweled neckline and pointy lace pumps, arrived on time to an empty front of the house. "I'm not an aficionado of these things, but it seems like the real deal," Ms. Mortimer said of the setting: booming classical music, a drawn-on tile runway and giant mirrors. I've been to a YSL show in Paris before and it was like this. Paris was familiar territory for the Courtins-Clarins trio (Virginie, Prisca and Jenna), who arrived a few minutes later. It wasn't enough to sit pretty, the skincare heiresses were also blogging for Clarins. Wasn't it a lot of work? "It helps there's a lot of us," said Virginie. Family ties mattered at Yigal Azrouel, whose show at the Highline Stages attracted the lion's share of pretty socialites. Perhaps they were less intriguing than Les Moonves and Julie Chen, who curiously snuggled front row. Aha! Mr. Moonves's daughter Sara was styling the show. Directly after, Kate Bosworth, tiny in a black fit and flare dress, slipped backstage at the Cushnie et Ochs show at Milk Studios. And there was Ms. Steinfeld again, later at Rag & Bone, where temperature control issues (read: no A/C) didn't detract from her wardrobe change: leather pants, boots, silky taupe button-down and gobs of black eyeliner. Predictably, she wasn't the only actress invited. There were also Maggie Gyllenhaal and Gabrielle Union, the latter clad in a lacy sleeveless top, burgundy shorts and boots. Ms. Union had fashion competition, but closer to home: her boyfriend, the basketball player Dwyane Wade "lives for fashion" and "lives for Anna Wintour," she said. "I'm like the consolation prize," Ms. Union joked. With hot young actresses in heavy rotation, expectations were high for Charlotte Ronson's evening show at Lincoln Center, where paparazzi nearly outnumbered the guests. What was all the fuss about? Apparently, Paris Hilton. Flanked by other socialites, strangely homogenous in little dresses, bronzed legs, and blonde hair, she fielded questions and flashbulbs with what looked like a secret smile of vindication. Fran Leibowitz, meanwhile, stood out in a mint green blazer and trousers. Eying the hoopla, she sagely said. If there's one thing you can count on, is that it doesn't change.
