Oscars 2013 Red Carpet: Fashion Experts Weigh In!

A-list actresses turn heads and exude old-Hollywood glamour on the Oscars carpet.

The Oscars is one of the biggest nights and film, and also one of the biggest nights in fashion. Hollywood's elite hit the red carpet at the Dolby Theatre on Sunday wearing the top designers in the fashion industry, and they did not disappoint.

From old Hollywood style and dramatic dresses to pale colors and glittery ensembles, A-listers showed off the hottest trends while vying to land a spot on the coveted best-dressed list.

"A lot of very classic, flowy pastels, softer tones, tousled hair," MTV Style senior editor Mary H.K. Choi told MTV News. "Not a lot of boldness in terms of hue or makeup."

Pale shades certainly dominated the red carpet, with Amy Adams, Amanda Seyfried and Charlize Theron all wearing the muted look. Yet it was Best Actress winner Jennifer Lawrence's strapless light-pink Dior gown, complete with a necklace that draped down her back, that turned the most heads.

"I did love Jennifer Lawrence's dress. It was voluminous, it was Dior. It was romantic. It was like the Gwenyth Paltrow Ralph Lauren," Choi said of Lawrence's dress, which reminded her of Paltrow's 1999 Oscar dress.

Lawrence's fellow Best Actress nominee Jessica Chastain also exuded retro glamour in a mermaid-style Armani Privé, and the soft color popped against her wavy red hair.

"[It's] a tough color to pull off. It's a golden nude. That dress was all about the fit," Choi said of Chastain's choice. "Armani Privé is just scintillating, but it was like something that was grown on her."

Another nominee dressed in Armani was the night's youngest attendee, 9-year-old Quvenzhané Wallis.

"She was wearing Giorgio Armani Junior, and the thing I liked, it was so age-appropriate," Choi said. "Really pretty. She had this tiara-esque headband on and the puppy purse."

The most talked-about look of the night had to go to Best Supporting Actress winner Anne Hathaway. Her Prada gown, which she "really liked," even though she picked it out three hours before the show, caused quite a stir, even spawning its own Twitter handle @HathawayNipple.

"She went with Prada instead of Valentino, and it was this white duchess satin and sort of bib-from-the-back dress, and it was very cute," Choi said. "I liked it because it was very '90s. I likened it to the metal-lunch-box phase because of the satin bib, but one thing is her hair is growing out great."
