A winner on and off the red carpet, this year's Best Supporting Actress Lupita's custom Prada dress was inspired by champagne bubbles.

Lupita Nyong'o in Prada: A winner on and off the red carpet, this year's Best Supporting Actress Lupita's custom Prada dress was inspired by champagne bubbles.

Cate Blanchett in Armani Prive: Cate Blanchett wore shimmering nude Armani, a popular choice with her, to collect her Best Actress Oscar.

Angelina Jolie in Elie Saab: This year's recipient of the Jean Hersholt Humanitarian Award wore sheer and sequinned Elie Saab, a welcome and very flattering change from her usual monochrome.

Jennifer Lawrence in Christian Dior: She may have gone home Oscar-less but Dior darling Jennifer's red number put her at the head of the fashion queue. Note to Jen though: you wore red in 2011 and lost Best Actress. A sign from the god of couture?

Amy Adams in Gucci: Best Actress nominee Amy's navy strapless gown was simple yet elegant.

Sandra Bullock in Alexander McQueen: Best actress nominee Sandra Bullock scored a hit in her deep blue gown with a sweetheart neckline that set off her curves to perfection.

Charlize Theron in Christian Dior: She wore pristine white last year and this year, Charlize was black gold in a dress with a sweeping train.

Emma Watson in Vera Wang: 10 points to Gryffindor for Hermione's classy metallic dress and red lipstick.

Naomi Watts in Calvin Klein: The Diana actress was a vision in a white sequined floor-length gown. We loved the way her blonde hair were pushed back from her face to draw attention to her dress.

Olivia Wilde in Valentino: The mom-to-be was radiant and glowing in a sleek black gown. She certainly didn't look seven months pregnant.
