Amy Adams
Amy Adams commands attention in her glittering, cap-sleeved L'Wren Scott gown. The Fighter star's loose, fiery waves and emerald-and-diamond Cartier necklace add pops of color to the midnight look.
Nicole Kidman
With its structured silhouette and graphic details, best actress nominee Nicole Kidman's Asian-inspired Christian Dior gown is just a little too busy.
Kudos to her however for adding color (Coral Pierre Hardy sandals) and the lovely diamond Riviere neck piece
Natalie Portman
Mom-to-be Natalie Portman -- a best actress Oscar winner for her dramatic turn in Black Swan -- looks positively radiant in her deep purple Rodarte gown. The V-neck draws attention up to her glowing face as the chiffon fabric flows beautifully over growing baby bump.
Halle Berry
Halle Berry turns heads in her jeweled, curve-hugging Marchesa gown -- and her dramatic tulle train adds an ethereal touch to her flowing frock.
Michelle Williams
Blue Valentine star Michelle Williams looks feminine and refined in her lilac, high-necked Chanel gown. The best actress nominee's gorgeous, elegant look is a fashionable change from her Golden Globes misstep.
Hailee Steinfeld
Her picture-perfect princess dress is the perfect choice for best supporting actress nominee Hailee Steinfeld. The full-skirted and beaded one-of-a-kind Marchesa gown keeps the 14-year-old True Grit star looking youthful, fun and glamorous for her first Oscars appearance. Even cuter: The teen star had sketched out her dream dress!
Sandra Bullock
Last year's best actress winner Sandra Bullock follows the red-dress trend with her eye-catching Vera Wang stunner. But its beautiful, artful bustle helps Bullock's gown stand out from the pack.
Annette Benning
The Kids Are All Right star Annette Bening, a best actress nominee, shines in a metallic column dress. Plus, the vertical jeweled stripes add extra glamour -- and drape her gorgeous figure perfectly!
Mila Kunis
Black Swan star Mila Kunis looks lovely in lavender on the red carpet. The presenter mixes romance with sex appeal with her soft, drapey Elie Saab gown with sheer lace accents.
Helena Bonham Carter
As always, best supporting actress nominee Helena Bonham Carter brings her own unique flair to the red carpet. The star of The King's Speech attempted to explain her gown's dramatic bustle, saying "I've got a bit of a complex with my bum, so I thought I'd make it even bigger." Love her sense of humor -- but with her shredded, velvet sleeves and messy, dated hair, Carter's costume-y look is a fashion miss.
Jennifer Lawrence
Less is certainly more for best actress nominee Jennifer Lawrence. The Winter's Bone star looks simple, subtle and red-hot in her understated Calvin Klein Collection gown and her soft, relaxed waves complement the look.
Gwyneth Paltrow
Performer Gwyneth Paltrow lights up the red carpet in her shimmery Calvin Klein gown. The fierce frock shines like liquid gold -- and her sleek golden locks finish off the look!
Penelope Cruz
Parenthood definitely agrees with this Oscar-winning duo! Just weeks after giving birth, Penelope Cruz shows off her sizzling post-baby body in a jeweled, ruby L'Wren Scott gown. And Cruz's handsome hubby, best actor nominee Javier Bardem, doesn't look too shabby, either!
Jennifer Hudson
Jennifer Hudson is on fire in this super sexy tangerine gown. In fact, the presenter (and past best supporting actress Oscar winner) told Ryan Seacrest that when she first tried on the dramatic Versace dress, she never wanted to take it off. We can see why!
Mandy Moore
Singer-actress Mandy Moore, whose song "I See the Light" from Tangled is up for best original song, looks grown up and glamorous in her sparkly Monique Lhuillier gown. Her elegant updo and luxe baubles help finish off the glittering look.
Scarlett Johansson
Presenter Scarlett Johansson looks ladylike and refined in her burgundy, lace Dolce & Gabbana gown. The curve-hugging silhouette and cut-out back take the look from sweet to sexy.
Melissa Leo
If The Fighter's Melissa Leo needed to check her makeup mid-show, her reflective dress came in handy! "I'm like a house of mirrors," the best supporting actress winner said of her stunning Marc Bouwer gown.
Cate Blanchett
Love the back and the embellishments and the constrasting colors and that Cate Blanchett takes a red-carpet risk with her structured, lilac gown. But the armor-like top is perplexing and looks like it's framing the actress' chest.
Marisa Tomei
From the waist up, Marisa Tomei's 1950 couture Charles James dress looks simple and elegant. But the eye-catching, full tulle skirt adds surprising element of drama to the vintage gown. However I found that it looked too petti-coat-ish and looks more like an undergarment tulle bustle.. Also the tulle and the satin are not the same shades..
Hilary Swank
With its ombre, feathered skirt and sparkly, sequined top, presenter (and past best actress Oscar winner) Hilary Swank's Gucci gown is a certainly a mix of trends. Luckily, the result is glam and gorgeous -- not overdone.
Florence Welch
Florence and the Machine's Florence Welch brings romance to the red carpet with her whimsical, vintage-inspired gown whch again looks like a petticoat. Only wish the singer had stepped it up a notch and opted for a more eye-popping color to complement her brightly hued locks -- like the silky orange dress she wore for her Academy Awards' performance of the best original song "If I Rise" from 127 Hours.
Camila Alves
Camila Alves' plunging black dress is anything but basic! Matthew McConaughey's leading lady stuns in an uber-glam Kaufman Franco ballgown -- and the side pockets add a playful touch.
Sharon Stone
Talk about sex appeal! Red-carpet veteran Sharon Stone proves she's definitely still bringing the heat in her one-shouldered Christian Dior gown. And her gravity-defying poof puts Snooki to shame!
Celine Dion
Hot mama! In her smoldering, white-hot Giorgio Armani Prive gown, you'd never guess performer Celine Dion gave birth to twins just four months ago!
Reese Witherspoon
Blonde beauty Reese Witherspoon channels cinematic legend Brigitte Bardot with her flirty, retro updo. Her classic, black-and-white Giorgio Armani Prive gown is sophisticated and elegant, and her shining baubles (including her stunning engagement ring!) help dress up the look.
Shaun Robinson
Shaun Robinson wore this blue Christiane King number with a giant flower on the bust/neck area.. Somehow the gown looked too prom-like and very under dressed.. Also the length in front was a bit too long.
Aishwarya Rai
Bollywood beauty Aishwarya Rai looked pretty in a antique beomze Armani Prive outfit accessorized with earrings, bracelet and a clutch.
Mallika Sherawat
Bollywood wannabe Hollywood star Mallika Sherawat almost looked good n this sparkly own by God knows who.. Of course she did have to go and spoil it by posing with her butt and chest out!
