New York Fashion Week Spring 2013 has come to a close, but before we move on to London, Milan, and Paris, let's look back on all the fabulous front-row celebrity styles that took place over the last week. Everyone from Olivia Palermo to Solange Knowles to Kate Bosworth to Diane Kruger and many more made fashionable appearances, so step inside to draw major style inspiration for your equally stylish life.

>> Kate Bosworth, Emma Roberts, Kirsten Dunst, and Elizabeth Olsen were among those who descended on Park City for this year's Sundance Film Festival. Though the weather provided plenty of opportunities for bundled-up Winter looks, there were just as many dressier moments to be had as well: Emma wore a body-con floral Topshop dress to the Celeste and Jesse Forever dinner, while Kate — in town for the premiere of her new film Black Rock — was spotted on the red carpet in a crimson, beaded Antonio Berardi number. See those looks — plus others — here, in the slideshow.

>> Erin Fetherston's name is typically associated with super feminine designs, but on the set of Paper's recent shoot, which captured women like Fetherston (below), Bergdorf Goodman SVP Linda Fargo, and Rachel Roy in menswear and mustaches, she admitted: "I've started to wear pants a lot, having been a dress-only girl for so many years. It's interesting to have a balance." Jenny Shimizu, who also took part, told Paper she's working on something new as well: a book of her life experiences, particularly "carousing around" in the '90s supermodel scene.

>> New York Mayor Bloomberg declared yesterday "Burberry Day," in honor of the lighting of the brand's logo atop its new US headquarters — watch a video of it going down here — and the weather complied with rain, appropriate for a brand known for their trench coats. "I was worried about the drizzle before, but now I love it," said Christopher Bailey, in town to celebrate. "It's all very English."

Christopher arrived to the unveiling last night with Lily Donaldson on his arm, who grinned and gushed about being "a Burberry girl" and "part of the [Burberry] family."  He went on to explain what an honor it it is to have the Burberry logo lit in the first place: "It's one of only six grandfathered buildings in New York where you can do that, so it's a big deal for us to be able to affect the iconic Manhattan skyline, which I love."

The excitement seems to have made him chatty — he covered a range of topics, from admitting that he dyed his hair blue once to discussing advertising fees — like Mario Testino's, which runs $140,000 a day: "You’re buying talent. And I think talent never goes away with the changing economy, and talent is something we all need to keep nurturing."

Models (Hilary Rhoda, Helena Christensen) mingled with editors (Kate Lanphear, who apparently has dyed her hair black underneath, Amy Astley, Cecilia Dean) and it girls (Byrdie Bell, Alexa Chung, Julia Restoin-Roitfeld, Harley Viera-Newton), and the mix left at least one girl confiding that she didn't recognize Blake Lively — Lily Donaldson, who admitted: "I don't watch Gossip Girl. But you can't blame me. I don't even own a TV at the moment!"

The celebration seemed a success, except for skimping in one area.  An alcohol shortage kicked in around 9:30 pm, leaving one guest unhappy: "That's the driest party I've ever been to."  Same goes for Harley, Leigh Lezark, and Derek Blasberg, The Cut tweeted: "The party has run out of glasses, and the trio is displeased."
