Old-school glamour on Oscars red carpet AFP 2/25/2013 12:35:43 AM Tinseltown's A-list stars offered up a healthy serving of old-school Hollywood glamour on the Oscars red carpet Sunday, with strapless gowns and pale colors most definitely in vogue.Best actress nominee Jessica Chastain, a frontrunner for Oscars gold for her role as a CIA agent tracking Osama bin Laden in "Zero Dark Thirty," sparkled in a strapless beaded flesh-colored Armani gown, her red tresses flowing."It's a 'Happy birthday, Mr President' kind of dress," Chastain said, referring to a classic Marilyn Monroe fashion moment. "It's an honor to wear a dress that evokes old Hollywood."But she told CNN her chances to win were slim: "I just don't think it's my year... I don't think I'm going to win."Chastain's main rival, "Silver Linings Playbook" star Jennifer Lawrence, strutted her stuff in a strapless cream Dior gown with a full puffy skirt."This was such a passion project for all of us," she told E! television on the red carpet, referring to the romantic comedy with an edge that earned a total of eight nominations, including one for best picture.Nine-year-old Quvenzhane Wallis, the youngest ever best actress nominee, for "Beasts of the Southern Wild," wore a bejeweled navy blue Armani dress -- accessorized with an age-appropriate fluffy puppy purse."It has been crazy!" Wallis said of all the attention given to her breakout performance, adding that her fellow nominees were "more sophisticated."Amy Adams, a best supporting actress nominee for her performance in "The Master," was on trend in a strapless pearly gray Oscar de la Renta princess gown with soft layers of tulle floating to the ground.Reese Witherspoon got the strapless memo, but changed up the color palette in a cobalt blue and black Louis Vuitton, and glammed it up with some old-school Veronica Lake curls tumbling down."Les Miserables" star Amanda Seyfried opted for a pale purple halter neck Alexander McQueen with a sexy keyhole neckline and upswept hair.Best supporting actress nominee and two-time Oscar winner Sally Field, who starred opposite Daniel Day-Lewis in "Lincoln," made a bold statement in a signature Valentino red dress with sheer long sleeves and a train.And she definitely won the award for best accessory of the night -- she arrived with "Lincoln" co-star Joseph Gordon-Levitt, who plays her son in the film, on her arm.For fashion and jewelry designers, having an A-list star show up on the Oscars red carpet in one of their creations is worth more than any print advertising -- thanks to the global coverage of Tinseltown's biggest night.Last year, Angelina Jolie's leg-popping appearance in a strapless black velvet Versace gown with a thigh-high slit went viral -- and gave the Italian fashion house unbeatable media exposure.
