This week's fab faves

Maybe the Victoria's Secret Fashion Show had something to do with it, because this week's looks are hot. Between all the LBDs making their way down the red carpet, there's a sultry side to each; then, a few surprises — vintage-inspired glam, and a dose of Fall's best trends via street style. For me, it's always a thrill to see how January Jones will play up a look, like a black sheath with back-revealing details. Katy Perry proved she's hot on stage or off, and Karolina Kurkova gives another amazing model moment, even when she's not dancing down the catwalk. Just click on for more of this week's Fab celeb looks.

From a slick leather LBD to a darling ladylike frock, fabulous wide-leg trousers to a polished structural number, this week's top celebrity looks totally titillated my fashion senses. It's been a while since we've seen Anne Hathaway in a dress, so that was quite a treat. Kylie Minogue continued her chic run in Paris, and Marion Cotillard made a dazzling appearance in an Elie Saab. Step inside to see more inspiring ensembles from our favorite celebs!

This week's celebrity looks range anywhere from blindingly bright to completely mellow. Case in point: bold beauties Kate Bosworth and Michelle Monaghan, and the serene Leighton Meester in nude and white Giambattista Valli. We love all colors here at Fab, from spunky to serious. Speaking of serious, there's some more seriously impeccable looks that came out this week — one casual cool, but mostly red carpet dazzling. Step inside to see it all.

The celebrity looks that stole the show this week were courtesy of some of Fab's faves: Sarah Jessica Parker, Kate Moss, Dree Hemingway, and Olivia Palermo. But the top prize goes to Olivia. I mean, the girl knows how to make even the most luxurious pieces look downright cool. Here is her latest NYC ensemble — part unapproachable glam goddess, part comfy downtown chick. Then there were some unexpected ladies in the mix like Selena Gomez, Cassie, and and Kristen Stewart, who looked more beautiful than ever before in Valentino. Black ruled, but tweed touches and camel also made cameos. Step inside to get a closer glimpse.

They're not the Fab regulars, but this week's stylish crew totally caught my attention by turning up their fashion game a few notches. Juliette Lewis proved that, along with her funky side, she has a polished, sexy one! Actress Paz Vega worked volume and ended up with one of the classiest looks of the bunch. And Maggie Q showed off her sexy limbs in a trendy long-sleeve mini. Fab favorite Carey Mulligan also makes a cameo in Proenza Schouler, as do Naomi Watts and Alexandra Richards. Click on to see why their looks were on my radar this week.

The celebrity looks that had my undivided attention this week were shimmery, sharp, black, bold. Sarah Jessica Parker got all dressed up for the ballet, Brad Goreski gave us a cool color palette, and Heidi Klum went wild. What's more, Sienna Miller showed off her new silky, peachy pants, Kate Moss tried the new longer hemline, and model Carolyn Murphy donned a suit so right. Step inside to see them all, and more.

First things first: how lovely does Rachel Bilson look sitting pretty in pink at Christian Dior's Spring '11 show at Paris Fashion Week? She's been on a major roll lately with her fancy frocks — did you see her in that leopard Roberto Cavalli? Damn! But Rachel's not the only lady whose style we're crushing on. Blake Lively leaves her minis behind for a more ladylike silhouette, Claudia Schiffer works plaid on plaid, and Vanessa Hudgens ditches boho for ultra-sexy. Ready for a celebrity fashion adventure? Step inside.

Let's start this week's Fab faves with a couple whose style is totally worth copying — Odette Yustman and Dave Annable. This duo never look shabby. Au contraire: they're always dressed to impress, in sync but not overly matching, and the same goes for their latest red carpet getup. In other celebrity style news, Sarah Jessica Parker makes two cameos, Taylor Swift impresses with her retro sweet frock, and Whitney Port hits us with yet another polished chic ensemble. Step inside to see them, and more of my latest style crushes.
