Styles of the stars -- A look at the gowns worn by actresses like Jennifer Garner and Laura Linney

Jennifer Garner
Oscar de la Renta
The black is safe. The shape is hardly revolutionary. But thanks to great hair and some well-chosen diamonds from Van Cleef & Arpels, the Juno star’s ruched ? ruffles took the cake on a rainy, underwhelming night for the ladies of Hollywood.

Helen Mirren
Georges Chakra
”Pretty amazing” is how last year’s Best Actress termed this custom-made duchess satin gown, accented with Swarovski-crystal sleeves perfectly befitting the queen. Tim Gunn told us she was one of his highlights — we firmly concur!

Laura Linney
Michael Kors
Linney’s flawless but dull navy gown is yet another testament to the power of accessorizing, as that Cathy Waterman pendant works overtime to make up for the too-plain palette everywhere else. Cameron Diaz, are you taking notes?

Anne Hathaway
The Get Smart star plucked this silk chiffon stunner off pal Georgina Chapman’s runway. Reports Hathaway: ”An hour later, every actress in Hollywood called and asked if they could wear this dress. And she didn’t give it to anyone more famous!”

Marion Cotillard
Jean Paul Gaultier
The Best Actress winner courted whimsy with flapping silver-tipped scales — either the most successful fashion risk of the night or a throwback to Darryl Hannah at the end of Splash. Surely you saw this joke coming: Ma Vie en Poisson!

Cate Blanchett
Dries van Noten
The encrusted halter and oddly placed floral bursts seemed a bit cheap (and the uneven hemline made us wonder if they didn’t allot enough fabric for the baby on board). But any pregnant lady who kicks it in Christian Louboutins earns our undying respect.

Nicole Kidman
Putting all her eggs in L’Wren Scott’s 8-kabillion-diamond necklace basket was a lazy attempt to spice up a snoozer. And sorry, Nicole, but showing up on the carpet at the last minute didn?t help ice over that fact.

Hilary Swank
Swank stepped out in one of the most intricately detailed dresses of the night, from the crisscrossed bodice and floral neckline to its subtle shimmer. Even Sean Combs took time out to comment on how well it worked. And if Diddy digs it…

Renée Zellweger
Carolina Herrera
She’s long since settled into a comfortable Herrera groove, but the slinky silver setup (slit up to there) confirms Zellweger’s impeccable taste. And the Cartier bracelets — a throwback o her brilliant Jean Desses success — make us swoon.
