Oscar Red-Carpet Fashion: Natalie Portman, Hailee Steinfeld Shine

Fiery reds and deep purples rule the Academy Awards red carpet.

The only dress code for the Oscars is glamour, and this year's red carpet certainly brought the dazzle. With lace and va va voom ruling the night, two celebrities in particular are guaranteed to have fashionistas buzzing around the water cooler on Monday morning. "Black Swan" star Natalie Portman and "True Grit" actress Hailee Steinfeld pumped up the glam on the carpet.

Oscar nominee Portman (and her ever-expanding baby bump) hit the carpet in a deep-purple off-the-shoulder billowy silk chiffon gown with sequin detailing by "Black Swan" costumers Rodarte. She completed the look with tassel earrings by Tiffany & Co.

Purple was a hot color on the carpet, with Portman's "Black Swan" co-star Mila Kunis dazzling in a lavender lace and silk organza gown by Elie Saab Haute Couture from the designer's spring 2011 collection.

Amy Adams also rocked a purple shade, wearing a deep-violet, sparkly cap sleeve dress by L'Wren Scott, accessorized with an emerald drop necklace. Cate Blanchett looked like a warrior in a structured lavender gown with cut-out detailing by Givenchy Couture. Scarlett Johansson looked chic and relaxed rocking wavy hair and a see-through purple lace Dolce & Gabbana gown that was made even sexier thanks to the cut-out back.

Red was the other big color of the night. Oscar host Anne Hathaway hit the carpet in a strapless red ruffled gown with a large bustle. "Winter's Bone" star and first-time nominee Jennifer Lawrence stunned on the carpet in a body-hugging, minimalist red dress by Calvin Klein Collection.

Oscar winner Sandra Bullock was sophisticated in her strapless red Vera Wang dress. And she may have just had a baby, but Penélope Cruz looked nothing less than "wow" in a red, beaded showstopper gown by L'Wren Scott. Jennifer Hudson also jumped on the red-hued bandwagon, looking svelte in a low-cut halter gown in orangey-red by Versace.

While color definitely ruled the carpet, not all of the stars went that route. Mandy Moore sparkled in a nude-color, off-the-shoulder dress by Monique Lhuillier, and Halle Berry looked ethereal in a feathery gown in a similar shade. Michelle Williams was still rocking the blond pixie cut, but this time she sparkled in a skintight nude-color cap-sleeve gown by Chanel.

Also opting for the pale trend was the Oscar nominee who'll have everyone talking: 14-year-old Steinfeld, who opted for an age-appropriate, blush colored 3/4-length ballerina-esque tutu dress with a large tulle skirt by Marchesa; that starlet worked with the designers to design the look.
