"I need 10 people to get up the stairs!" said the night's Best Actress winner as she entered L.A.'s Dolby Theatre in a Dior Haute Couture gown and Chopard jewels with a Roger Vivier Boite de Nuit clutch.
"It's a very 'Happy Birthday, Mr. President' kind of dress," said the actress (in Giorgio Armani and Harry Winston jewels). "It reminds me of Old Hollywood glamour."
"I worked with Oscar de la Renta," said the Best Actress nominee of her custom confection, which she paired with Mouawad jewels. "I've always wanted to wear a princess dress, and now is finally the time!"
Best Long Sleeve
"I wanted to go as a Bond Girl to the Oscars," said Berry, who wore a custom-made Atelier Versace gown, Jimmy Choo heels, Adeler earrings and a Le Vian ring.
Best Shoulder Detail
"It's architectural and art deco, almost like the Chrysler building," says stylist Jeannann Williams of the star's custom Giorgio Armani gown, which she wore with Neil Lane jewels.
Best Beaded Bodice
"As soon as I tried it on, I stopped trying on anything else," says the Django Unchained
star of her Miu Miu gown, which she accented with Chopard earrings and a Fred Leighton ring.
"I just love the color," said the presenter, whose daughter Ava, 13, helped her choose the custom gown and jewels by Louis Vuitton.
With the star's son Jackson, 1, running around, "we didn't put the dress on until the very last second," says stylist Leslie Fremar of Theron's Dior Haute Couture gown and Harry Winston gems.
"This gown can hold a village underneath!" said Aniston of her Valentino Haute Couture gown, which she paired with a Salvatore Ferragamo minaudière and Fred Leighton jewels.
