Top 10 celebrity looks of the week

Between the Fashion Week craziness, celebrities are suiting up in style for their respective red-carpet outings and parties. In light of Fall, we're seeing a return to trousers, slick suiting, and layers, though, of course, there are a few sweet shifts and colored frocks — we're looking at you Kate Bosworth and Zoe Saldana — to capitalize on the last of the warmer weather. Click through to get a glimpse of this week's standouts, from Madewell's It girl, Alexa Chung, to hot mama-to-be Beyoncé — there's plenty of inspiring style in store.

This week, celebrities kicked off their stilettos and opted for street-ready wear. On the whole, we spotted our favorites channeling a more casual vibe, and more in the way of seasonal ensembles as the weather slowly warms. Alexa Chung gave us her version of denim on denim, Diane Kruger and Whitney Port both showed off their stems in day dresses, and Rachel Zoe continued to wow us with impeccable pregnant style. As always, the weekly rundown is a pretty chic bunch — click through to see who we loved!

It's been a week since NYFW kicked off a stylish season, and celebrity style shows no signs of slowing down. Whether gathering for more shows in London and Milan, kicking off a movie premiere, or prepping for Oscars, we caught some of our favorites making fashionable arrivals in everything from liquid leggings to shimmery cocktail attire. Highlights from Jennifer Aniston — and her newly cut locks — Alexa Chung taking in LFW in leather, and Elle Macpherson in a fierce, fringed LBD.

This week, our favorite celebs flew east to NYC to take in the Fall shows. Of course hitting the tents at Lincoln Center is a full-on fashion frenzy in itself. So, beyond the looks coming down the runway, we had our eyes on the styled faces sitting front row and hitting fashion's best parties. Take a peek at the top 10 now!

From the sidewalks of London to the boutiques of Los Angeles, celebs turned up their style dial this week. Leighton Meester promoted her new flick The Roommate, which meant she wore a bunch of new outfits. One of them turned us off, but one turned us way on! Likewise, Jennifer Lopez lent mega shine, Heidi Klum worked color, and Beyoncé proved that just because she's taking a business meeting doesn't mean she turns her fierce-o-meter off.

Dining with the Fab faces of Paris Fashion Week or making a statement at Sundance demands a certain amount of style. Clearly, our celeb favorites were up for the challenge, making styled appearances at both major events — and everything in between. Among the standouts this week: Minka Kelly getting glam for her premiere, Diane Kruger donning Chanel, Kate Bosworth balancing cozy and cool in Sundance, and Thandie Newton looking chic in London. Of course, these ladies are just a handful of the fashion pack; click through to see the rest of the top 10.

This week's style crowd turned out looks ranging from a sultry take on boots and denim — Hilary, I'm looking at you — to the sweeter side of things, like Gwyneth's pink Azzedine Alaïa. As always, I love that all the looks are different, that everyone has a way to rock their signature style. While that might mean a cool-girl take on street style for Jessica Alba, it's all about maxi, '70s-inspired style for mama-to-be Rachel Zoe. Like I said, really, the only common ground for these looks is that they're all on my style radar — click through to see why.

This week's stylish bunch churned out looks ranging from vintage-inspired to fabulously frilly to casual cool, but the common denominator is that they all caught my eye. Charlize Theron and Alessandra Ambrosio proved that dressing down doesn't have to equal sacrificing style — au contraire! — while Eva Mendes gave us a flair for the exotic. Cameron Diaz mixed whimsical with practical, Sienna Miller mimicked Little Red Riding hood, and Elle Fanning proved she's a rising style star. Step inside to see them and more!

Celebs were all over sexy black lace this week! Kirsten Dunst, Hilary Swank, and Rosamund Pike all donned the dainty fabric in their own fabulous ways. But the real stunner was Natalie Portman. And why not? It's her big Black Swan opening week. The black Christian Dior gown she wore to the NYC premiere was perfection — the way the sleeves fell off her shoulder, the detailed ruching on the bust, the smooth dip in the front. Step inside to get a closer look and to see which other celeb looks I was crushing on this week.

There were many looks I admired this week, but I have to admit, one outfit titillated my eyeballs like no other. Can you guess which one of these three? If you said Karolina Kurkova in the red suit, you're right. Everything from her messy tresses to the fit and color of the suit to the black touches was on point. Now if only I can find me a similar suit! Besides Karolina, Blake Lively and Nicky Hilton also rocked their looks like stars. Step inside to see these three ladies, including a few more who stole the show this week.
