Takeaways from the Oscars red carpet

Hollywood's top stars oozed glamour on Sunday as they hit the Oscars red carpet under sunny skies in plenty of bling -- and with oodles of attitude.

Here are a few key looks and trends from the A-list fashion parade at the Dolby Theatre:

- Belle of the ball -

Sweden's Alicia Vikander has taken both the acting and fashion worlds by storm in the past year. On Sunday, she looked like the princess of Hollywood ready for her Oscars close-up. And she took home a golden statuette.

A best supporting actress winner for her role in "The Danish Girl," Vikander floated onto the red carpet in a strapless pale yellow Louis Vuitton gown with silver accents and an asymmetrical hemline. Her brown tresses were in a half up-do, most of it hanging loose and curly down her back.

On Twitter, some compared her look to that of Belle in the Disney classic "Beauty and the Beast." Not a bad call.

- Shades of blue -

Blue skies and warm temperatures greeted Tinseltown's elite. And they responded by embracing blue as the color of the moment.

Best actress winner Brie Larson, who earned the Oscar for her searing performance as a kidnap victim in "Room," wowed in a bright blue Gucci gown with a floating skirt full of pleats and a silvery belt.

"This has been a dream of mine since I was seven years old," she told E! television, referring to just being an Oscars nominee.

Sofia Vergara, the star of television's "Modern Family" and a presenter on Sunday, stunned in a sweetheart-neckline navy blue Marchesa gown that showcased her oft-talked-about curves.

Best actress nominee Cate Blanchett ("Carol") flashed some cleavage in her romantic, blue-green Armani gown with flower petal accents.

Patricia Arquette and Naomi Watts also graced the carpet in shades of blue.

- White hot -

White is not the easiest color to wear for most women. But Hollywood's A-listers are fearless.

Rooney Mara, competing against Vikander in the best supporting actress category for her role opposite Blanchett, looked edgy in a long-sleeved white Givenchy lace gown with a diamond midriff cut-out.

Pop diva Lady Gaga -- nominated for an Oscar for her song "Til It Happens to You," from the campus rape documentary "The Hunting Ground" -- stunned Oscars fashionistas with her white gown-pantsuit combo by Brandon Maxwell.

- Plenty of jewels -

The dresses are often the focus on the red carpet, but the jewelry is also worth a look.

Eye-catching earrings are de rigueur. Saoirse Ronan, a best actress nominee for "Brooklyn," paired her emerald green slinky sequined Calvin Klein gown with -- mismatched earrings, one green and one white!

Britain's Daisy Ridley, the heroine of "Star Wars: The Force Awakens," wowed the crowd in a silvery Chanel gown -- suitably sparkly for the star of the latest chapter in the intergalactic space saga -- and an eye-catching chunky ring-bracelet combo.

And Charlize Theron, the statuesque star of "Mad Max: Fury Road," looked stunning in a red Dior gown with a plunging neckline -- and a long head-turning Harry Winston diamond necklace.

- Don't forget the gents! -

Sylvester Stallone, whose loss to Mark Rylance in the best supporting actor category was one of the surprises of the night, looked slick in a blue dinner jacket with black and blue lapels, and a black shirt and bowtie.

"It's been a most memorable year," the "Creed" star, who reprised his iconic role of boxer Rocky Balboa, wrote on Instagram.

Eddie Redmayne, who won an Oscar last year for his portrayal of Stephen Hawking in "The Theory of Everything" and was a nominee again this year for "The Danish Girl," looked sharp in an Alexander McQueen tux with a velvet jacket.

But he said he misjudged the warm weather.

"I thought it would rain this year so I wore velvet, and I'm sweating like a fiend," he told ABC on the red carpet.
