HOLLYWOOD, United States: Hollywood's A-list stars exuded subtle elegance and old-school glamour on the Oscars red carpet Sunday, as the sun came out just in time for Tinseltown's biggest night of the year.
Lupita Nyong'o, the winner of the Oscar for best supporting actress for her searing turn in "12 Years a Slave," rocked a sleeveless pale blue pleated Prada gown with a deep-V neckline -- and a headband.
"It's a blue that reminds me of Nairobi. I wanted to have a bit of home," the Kenyan actress -- who has become a darling of fashion critics during Tinseltown's awards season -- told E! television's Ryan Seacrest.
Australian actress Cate Blanchett, who took the best actress prize for her work in Woody Allen's "Blue Jasmine," sported a gauzy bejeweled nude Armani gown.
"It's heavy but I love it," she said.
Pale gowns were a frequent sight on the red carpet: Blanchett's co-star Sally Hawkins, best actress nominee Meryl Streep, "Frozen" star Kristen Bell, Naomi Watts and French actress Julie Delpy all rocked the trend.
Best actress nominee Amy Adams, who donned sparkling glam 1970s gowns with deep cleavage in "American Hustle," was understated and flawless in a strapless deep blue Gucci gown with peplum detailing.
Adams admitted she wore her long red tresses in a bun because of the threat of rain, and told ABC the up-do was inspired by Kim Novak's look in the Alfred Hitchcock classic "Vertigo."
Her "American Hustle" co-star Jennifer Lawrence, who competed against Nyong'o in the best supporting actress category, was striking in a strapless red Christian Dior peplum gown and slicked-back short hair.
In a scene mirroring her famed fall last year as she went up on stage to claim her best actress trophy for "Silver Linings Playbook," Lawrence slipped on the red carpet Sunday.
"If you win tonight, I think we should bring you the Oscar," host Ellen DeGeneres quipped at the start of the broadcast.
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 the awards ceremony.
Idina Menzel, who performed the nominated song "Let It Go" from the Disney animated hit "Frozen" during the broadcast, wore a strapless hunter green Vera Wang gown with a sweetheart neckline and a long train on the red carpet.
She changed into a frothy pale Reem Acra strapless gown worthy of an ice princess for her performance.
- Men show some flair -
Hollywood's men, not to be outdone, had a few fashion statements of their own to make.
White dinner jackets were all the rage -- Matthew McConaughey and Jared Leto, both winners for their roles in "Dallas Buyers Club," adopted the trend.
McConaughey's bow tie was black, while Leto's was burgundy.
Leonardo DiCaprio, a best actor nominee for "The Wolf of Wall Street," and Kevin Spacey, a producer of best picture nominee "Captain Phillips," both sported blue tuxedos.
Pharrell Williams, a nominee in the best original song category for "Happy" from "Despicable Me 2," sported a classic tuxedo jacket... and long shorts, designed by Lanvin.
But for his performance, he donned a black version of the huge Canadian Mountie-style hat designed by Vivienne Westwood that he wore to the Grammys in January, creating major fashion buzz.
