In her downtime, K.Stew's more comfortable in a T-shirt, jeans and sneakers, but the Twilight Saga actress has really stepped it up when it matters most on the red carpet. Kristen's gone from reluctant style star to full-blown fashionista this year, vamping it up in some amazeballs gowns to promote Breaking Dawn: Part 1, thrown into the mix along with her signature edgy minidress-and-stiletto combos. We couldn't be prouder!
Nobody loves her LBDs more than this famous Friend, but this year Jen fearlessly ventured out of her comfort zone and experimented with colors, prints and even chopped her golden mane! Perhaps the actress's newfound love of fashion had something to do with the fact that she also fell in love with a hot guy? Just a hunch. But what we know for sure is that this new and improved, classic-with-a-twist Jen is more stylish than ever. Bonus: This lady's never been accused of wearing a boring pump.
The blockbuster Harry Potter franchise came to a close this year, but it's certainly not the last of Emma that we'll see on the red carpet. From the final H.P. premiere to more recent events—including the My Week With Marilyn screening (center) and a Lancome launch (right)—the 21-year-old star is still casting her spell on us in her chic, tasteful and fabulous outfits. Now this what growing up gracefully in Hollywood looks like.
So the thing about the Friends With Benefits star is that she seems really laid-back and chill, you just want to hang out with her and relax over some beers—she's that cool girl. But then Mila has this other side to her in which she dresses up for the red carpet and knocks it out of the park nearly every time in her sometimes edgy, sometimes girlie, but always fabulous couture. She's high, she's low, she's awesome.

This year, Zoe's been kicking ass and taking names on the movie screen (Colombiana, anyone?) and the red carpet. And though her fashion choices haven't been as avante garde as they were last year (which helped her land on 2010's list), she's still dazzling in that effortlessly glamorous, totally pulled-together and pretty way that only she can do.
So this diva has had her ups and downs this year (in her personal life and on the red carpet), but when J.Lo gets it right, she gets it sooo right, and that's why she deserves a spot on this list. From her fierce Glamour event gown (left) to her sexy and stunning green Versace getup (center), Jen's had some jaw-droppingly stunning moments in 2011. This star has certainly ended the year on top!
This Gossip Girl star is all about taking risks and having fun with her fashion. It doesn't always work out, but, well, a lot of the time it does! (Those enviable gams and her sexy cleavage help, too, but we're not hating!) Most important, the blond babe does it all without the help of a real stylist. Now that's just unheard of in Tinseltown, isn't it?
Out of all the young stars in Selena's peer group (hello, Miley, Taylor and Demi), Selena is hands-down the best dressed of the bunch. The 19-year-old's got fabulous taste in shoes, her outfits are always youthful, fun and age- and event-appropriate, and she's oh-so-poised on the red carpet (no slouching here!). Disney wants a role model? They got one right here.
Diane's been MIA from the red carpet lately, but lest you forget the sensational first half of this year that she had, let us remind you with these amazing pics. This fashion badass shut it down on nearly every red carpet she walked. The attitude, the confidence, the beauty—Kruger's got all the right moves to pull off her couture choices beautifully. 'Nuff said.
This year's breakout fashionista—and one of our top girl crushes—is Emma. The Help star obvi needs no help in the wardrobe department, making bold choices that are often fashion-forward and interesting. It also helps that she's got her pick of the top designers, including Lanvin, Preen and Tom Ford. And most important of all, Em never gets predictable or boring on the red carpet. She could have easily gone the safe route, wearing the cookie-cutter Hollywood starlet uniform of skintight bandage dress and pumps, but nope—each look is new, different and totes exciting. Love it!
After marrying her prince in a fairy-tale wedding, this commoner turned duchess became the most-watched fashionista in the world. That's a whole lot of pressure on a 29-year-old, but Catherine has handled it like a pro. Starting with her incredible and timeless Sarah Burton for Alexander McQueen-designed wedding gown, Her Royal Highness hasn't had one single fashion fail to date—she's always dressed impeccably in tailored, classic clothes that suit her slim physique. Bravo, Kate.
