When in Rome . . . that seemed to be the motto adopted by Donatella's party guests at her SoHo store opening last night. The celebrity party guests, a crowd that included Kanye and Lady Gaga, showed their support for Versace in a range of the label's high-impact wares. Even Alexa Chung, who doesn't exactly strike us as a high-drama Versace girl, embraced the night's theme, albeit tempered with her own charm, in a burgundy leather skirt by Versace's younger line, Versus. Meanwhile, the supermodel contingent, including Coco Rocha and Bar Refaeli, took a page right out of Donatella's book, as did Jennifer Hudson, who joined the leather-clad crew of models in a fit-and-flare skirt and knee-high boots.

Elle's annual Women in Hollywood celebration is just that — a celebration of the biggest names in the business and a culmination of our favorite style setters. With Calvin Klein cosponsoring the affair, you might suspect that several of the attendees opted for the label's minimalist line of dress, and you'd be right — just look to SJP in a Calvin Klein Spring '13 strapless — but that didn't stop fashion favorites from showing off a few other choice designers, like Emma Stone in a fuchsia Valentino confection. As for the most dramatic of the night's arrivals, Lea Michele pulled out all the stops in a sheer-striped Zimmermann gown, proving just how much the dress code varied among this bevy of TV stars, Hollywood heavyweights, and fashion A-listers.

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.

Sometimes all it takes is the perfect weekend equation to bring about a veritable parade of covet-worthy dresses. Case in point: the Veuve Clicquot Polo Classic in LA inspired more than a few starlets to come to the polo field wearing their Saturday best. Mandy Moore's purple Lela Rose number catered to Fall's textural intrigue, Ashley Greene showed off a sexier bondage-infused side in an Antonio Berardi LWD, Alessandra Ambrosio's colorfully pleated BCBG maxi dress reminded us there's always a way to keep Summer's softer side intact, and Lauren Conrad, in her own Paper Crown design, proved that polka dots can be totally chic, too. Beyond that we've got an enviable lineup not to be missed courtesy of Ashley Madekwe, Rachel Zoe, Selma Blair, Ali Larter, and more.

Aside from the action at last night's AMAs, the weekend was filled with parties and premieres — and with each one, a bevy of celebrity beauties walking the red carpet. The cast of Gossip Girl gathered to toast their 100th episode in style, while Beyoncé hosted her own soiree to celebrate the launch of her new DVD. Meanwhile, across the pond, a chic Emma Watson stepped out for the premiere of My Week With Marilyn. Among the styled crowd, we spotted Blake Lively in a flirty Marchesa frock hitting the scene with Leighton Meester in Balmain, and Gossip Girl fan Chloë Moretz in Stella McCartney. Meanwhile, glowing mom-to-be Beyoncé slipped into a curve-hugging black gown for her celebration.
