Best of Look of the Day
This year Hathaway favored quirky feminine looks (courtesy of super-stylist Rachel Zoe) like her frilly Oscar de la Renta cocktail dress (left) and rose-red Marchesa gown (right). "If you're going to be glamorous, it has to be tempered with eccentricity so that it incorporates your own personality," the actress told In Style. "Dressing up is great, but you need a twist."
In 2008, Theron was flawless in a covetable custom Dior gown (left) from John Galliano, who calls the star, "so involved and creative." Meanwhile, her figure-flattering downtime style (right) was proof of what stylist Becks Welch deems her "great eye" for clothes.
Holmes set the styles this year in pulled-together ensembles from her favorite designers. "I've always been interested in fashion," she told In Style. "I grew up with stacks of magazines." Her style acumen-and her legs-were on display in both a Fay mini-trench (left) and a draped Alexander McQueen dress (right).
Beckinsale knows pretty! The British beauty played up her pink-and-white features in ruffled Prada (left) and a single-shoulder goddess gown from Derek Lam (right).
"I love to mix things up," Bilson has said of her signature style. "I love using basics as a canvas, combining them with vintage pieces or piling on accessories." The star was effortlessly eclectic in a vintage black dress and Martin Margiela boots (left) and a Monrow motorcycle jacket, paired with Seven For All Mankind jeans (right).
When she's not wearing her own line, this year the Hills fashionista selected body-conscious pieces from brands like D&G (left). And the ever-stylish star didn't slack when it came to casual-she sported separates like a brilliant red skirt (right) from pal Whitney Port's line, Whitney Eve.
This year Mendes was uniformly stunning on the red carpet, even though her style can range from edgy Calvin Klein Collection (left) to ultra-ladylike Bill Blass (right). As the actress told In Style, "I dress for my mood, and since I don't have just one mood, I don't have just one style."
Diaz legged it on the red carpet this year in minidresses from Zac Posen (left) and Missoni (right). But even when off-duty, the actress displayed her own brand of laidback chic. "I don't like overdone or being too put-together," Diaz told In Style. "I like casual chic. Eclectic style. I want to feel like I can go anywhere, whatever I'm wearing."
The Women's Murder Club star knows timeless clothes. Harmon showcased her classic beauty in a signature red dress from Valentino (left) and little black dress, also from the label (right).
Becoming the mother of twins didn't slow down Lopez's 2008 style. The superstar wore a Bensoni coat for an N.Y.C. stroll (left) and lavender Versace (right) for an after-dark event.
Richie brought '60s chic to the red carpet this year. The newly-minted jewelry designer channeled Brigitte Bardot in a sequined Reem Acra gown (left) and had flower-child style in Missoni (right).
