Donatella Versace called her Resort 2013 collection "rockmantic," and with all the studded leather pieces and floral prints it contains, it's an appropriate distinction. The offering was partially influenced by the Memphis design movement of the 1980s, which explains why many pieces were brightly colored — and why the print featured on jackets, pants, and dresses juxtaposed images of guitars with flowers and shoes. As is her custom, Versace nodded to her roots by forming the rose gold snaps on a cotton jacket into the shape of the house's Medusa logo.

In a burgundy and white dress from Chanel's Resort 2013 collection at the Los Angeles premiere of The Amazing Spider-Man, Emma Stone continued her recent trek of chicness — but there were other knockout looks this week as well. Sofia Coppola, for one, who got a head start on Resort 2013 when she wore a sequin striped number from — who else? — good pal Marc Jacob at the amfAR Inspiration Night in Paris. Dita Von Teese also sported Marc Jacobs at the amfAR event; the actress chose a sparkling brocade from the designer's Fall 2012 collection.

In London, the Serpentine Gallery Summer Party, hosted by designer Leon Max, brought a stunning crowd and an equally stunning assortment of ensembles: Laura Bailey, Erin O'Connor, Cara Delevingne, Florence Welch, Clare Waight Keller, and Caroline Sieber (left) were among those who turned heads.

All those — plus Rose Byrne, Blake Lively, Karlie Kloss, Daphne Guinness, and more — here, in our best-of-the-week slideshow.

The intersection where form and function seamlessly meet is never more necessary than in the throes of Summer's hottest heat. Who among us, after all, enjoys the burden of a two-ton leather tote whilst also struggling to maintain what little semblance of chic remains on a 90-degree day? No, better to travel light.

Nowhere was evidence of that in fuller view than at last weekend's Governor's Ball music festival on New York's Randall's Island, where — as the guests of those endless purveyors of effortless-breeze, Alternative Apparel — we spotted what every Summer-loving lass worth her style salt knows: when the sun beats down, crossbody bags are the way to go.

From Derek Lam's studded Ume to Chloé's Marcie in the dreamiest shade of teal green — and every free-spirited incarnation in between — here are 18 long-strapped goodies, as snapped on the coolest of festival beauties.

Alberta Ferretti fused '70s style with modern tailoring and romantic details for Resort 2013. Tie-dye prints abounded on everything from short suits to cigarette pants and knee-length jackets, while floor-sweeping gowns were spun out of lace and vibrantly colored crochet knits. Other pieces, like an elegant blush-colored gown and a sheer sleeveless shirt, were decorated with Murano glass beads.

It's Fashion Week . . . again! And though this go-round is technically all about the men's shows, that doesn't mean there's any shortage of ladies' street style to inspire. So far, there have been head-turning appearances by Caroline Issa, J.J. Martin, Giulia Tordini, Eleonora Carisi, Margherita Missoni, and Anna Dello Russo — just to name a few. What have they been wearing? Oh, only the most eye-popping assortment of patterns, brights, and prints imaginable. All the chicness, here, in the slideshow.

Olivier Theyskens's Resort 2013 is filled with the sorts of slouchy-sleek separates that can't help but exude an intrinsic sense of cool. Fitting then that the collection would be a personal favorite of someone who also can't help but exude that same sense of cool: Taylor Tomasi Hill. The former Marie Claire style director and current Moda Operandi artistic director took time out to walk us through her favorite picks from the collection — now available for a limited time for preorder — and spills how she would style each piece. From a leather pair of short-shorts to an oil-slick burnout sweater to the gauziest multicolored sparkling top, they're all here, and they're all totally covetable. After all, as Tomasi Hill says, "Who doesn't need a sequin crop tee? Olivier Theyskens made me realize I absolutely need this one."

Colorful party dresses that sparkle with vim and optimism were the bulk — and, in fact, almost the entirety — of Erin Fetherston's Resort 2013 collection. The plentiful frocks came in bright hues of turquoise, orange, and pink, and a few were decorated with oversized bows. There were a few separates in neutral colors — a white jacket and gray cardigan, for example — and lace dresses in black, white, and navy looked especially demure next to their shimmery cousins. While a few short dresses had front panels liberally sprinkled with sequins, an excellent pink number was covered with them from neckline to hem.
