Alexa Chung at Glamour Party | October 2012

When Glamour hosted its "These Girls" event last night in NYC, it was these girls: stylish attendees like Alexa Chung, Rashida Jones, and Coco Rocha, who stepped out to join fashionable forces and show off their Fall styling game. Just in time to inspire your own seasonal looks, Alexa and Rashida offered perfect plays on Fall-appropriate party dressing, with Alexa in a sweet printed dress, tights, and loafer combo, and Rashida keeping it more classic in a fit-and-flare LBD and Valentino heels. For a more alternative route, we'll look to Coco, who decked out a pair of tartan trousers with a velvet blazer and booties for a cool-girl play on prep-school styling. As for the other notable arrivals (like Olivia Wilde in a slick leather look), you'll have to click through — then be sure to tell us who gets your vote for best dressed of the night.
