Celeb Style

Julianne Hough took some fashion risks over the week in two bold-colored dresses for the Rock of Ages premieres in LA and Miami — and we think it totally paid off. She channeled her inner rock star in a figure-hugging blue leather minidress by Milly, and we really like this edgier style on Julianne. She then slipped into something a little bit sexier, choosing a hot yellow neon gown by Kaufman Franco for the LA premiere. Watch today's FabFlash to see both of her standout looks. On Allison McNamara: Topshop blazer and blouse.

Jennifer Aniston made a cameo at AFI's Life Achievement Awards last evening to support her Rumor Has It costar Shirley MacLaine. For the event, Jennifer slipped into a body-hugging Burberry gown showing a low neckline, thigh-high slit, and sexy cutout back detailing. Jennifer's look is the perfect way to ease into Summer style; just watch today's Fab Flash to hear more about her monochromatic ensemble.

Stripes are a classic Summer trend — they're crisp, clean, and can be outfitted to suit so many different occasions and styles. We spotted not one, but four celebrities out and about yesterday wearing striped tops, including Jessica Alba, Karolina Kurkova, Sarah Jessica Parker, and Ashley Greene. Watch today's Fab Flash to see how they put their own personal spin on this wardrobe staple. On Allison McNamara: Quiksilver Women top, House of Harlow 1960 necklace, JewelMint ring.

Alexa Chung styled up her ladylike best for the VIP preview of the Royal Academy of London Exhibition. The style setter chose a mod sheath dress by Moschino for the affair, complete with tiny pockets, ruffles, and pearl-encrusted gold buttons. We love how she balanced out the ladylike vibe with a playful raffia clutch decorated with flamingos and palm trees. Watch today's Fab Flash to see more! On Allison McNamara: Topshop blouse.

Kristen Stewart stepped out for the LA screening of Snow White and the Huntsman in a head-to-toe menswear-inspired Stella McCartney outfit. She started off with a high-collar blouse buttoned all the way to the top for polish and complemented it with a black double-breasted blazer. Kristen then injected a feminine feel via a flouncy miniskirt and pointy-toe platform heels. Keep watching to see more of Kristen's borrowed-from-the-boys ensemble! On Allison McNamara: StyleMint top, American Apparel skirt.

It's no secret that we adore Olivia Palermo's effortlessly polished style, and last night she showed off a look that is perfect for a hot Summer night. She attended the store opening of Fabergé's flagship store in NYC, and showed us how to elevate a stripe tee with suiting. Of course with Olivia, it's all about awesome, unexpected accessories. She rounded out her look with satin blue Manolo Blahniks and a Faberge silver chain necklace. On Allison McNamara: American Apparel top, Target belt.

After a whirlwind circuit promoting her new movie Snow White and the Huntsman alongside Charlize Theron, Kristen Stewart is now at the Cannes Film Festival, and made a very stylish first appearance in the South of France. Kristen tried out Spring's printed pants trend, choosing a pair of primary colored, statement pants by Balenciaga. She kept the rest of her outfit simple with a tailored blazer, white tank top, and classic black heels, while alongside Kirsten Dunst, who looked lovely in white. Watch today's Fab Flash for all the details. On Allison McNamara: Topshop blazer, H&M top, Lia Sophia necklace.

Lea Michele turned up the heat in a sleek LWD for the taping of Late Show With David Letterman. The Glee star arrived wearing a metallic blazer and miniskirt but slipped into something a whole lot sexier for the show, choosing this Amen frock with a low neckline and side cutouts. Lea snagged the No. 14 spot on Maxim's Hot 100 list, even beating out Kristen Stewart, who came in at No. 15. Watch today's FabFlash to see Lea's sexy style. On Allison McNamara: Rebecca Taylor dress, Honey Rose & K necklace from Thread on Grandview.

Fresh off a glamorous weekend at the Met Gala, Jessica Alba stepped out in NYC in an effortless off-duty look while lunching with friends at the Soho Grand. She styled up a breezy, monochromatic ensemble that's spot-on for transitioning into warmer months, pairing a lightweight gray sweater with white cropped pants and nude heels. Watch today's Fab Flash to get all the outfit details. On Allison McNamara: Topshop blazer.

One trend that we are really looking forward to for Spring is pastel pants, and we spotted Jessica Alba rocking not one but two pairs of these while sightseeing in Paris! First, she wore a mint-green pair when she landed in the City of Light, and then selected a bright pink version for soaking up the beauty in the famed Jardin du Luxembourg. Since these pants definitely make a statement, we love that she tempers the bold color with a black coat and matching black ankle boots. Watch to see both outfits in today's Fab Flash. On Allison McNamara: Rebecca Taylor top.
