"So far, I've only worn things that I feel speak to me," Nyong'o, 30, said when asked on the red carpet about her recent series of fashion hits. The Yale graduate did not disappoint.
Sofia Vergara of Modern Family left home her signature slink and opted for a ball gown by Zac Posen (though she changed into a skintight number for the afterparty). Vergara said she felt as if she were carrying a tent, but I loved the black gown's big proportions. And the Lorraine Schwartz turquoise necklace amplified the amazing factor.
Speaking of ball gowns, Kaley Cuoco's strapless, corseted floral Rani Zakhem celebrated all things watercolor and whimsical.
Zooey Deschanel bravely rocked a shimmering champagne Oscar de la Renta featuring a cropped top and high-low skirt. And Elisabeth Moss did her version of evening-wear-edgy in a burgundy J. Mendel. This, darlings, is how you do modern-day mixed media. (Something tells me salons are already taking calls requesting her razor-cut bob.)
Cate Blanchett was so very vampire chic in her lacy Armani gown. The plunging back V erased any ideas of modesty established by the dress' front.
Speaking of sultry, Margot Robbie's eggshell Gucci, in all of its sparkling emerald-green trim, was another example of a demure look with a white-hot soul.
I'm probably standing solo on a fashion precipice here, but I didn't mind Julia Roberts in what looked like a black strapless gown over a white button-down shirt. Call it Dolce & Gabbana tuxedo chic. Odd, but OK.
There was certainly something to say about those who were expecting: Drew Barrymore's pink Monique Lhuillier was a sweet look that took guts to wear - floral 3-D vines crisscrossed a big belly, after all. But she looked pretty, and she glowed.
Kerry Washington's much-talked-about smoky Balenciaga was classic and simple - but for someone who always wears zingers on the red carpet, this was a little boring. Where was the Washington oomph?
The best pregnant look was Olivia Wilde's, who wowed in a green Gucci. (Gucci gowns were my favorite of the night.)
Prabal Gurung designed the night's cutest looks, including Zoe Saldana's fun, mixed-media strapless slip dress. Saldana said her friend designed it with her in mind. And Sandra Bullock's floor-length fit-and-flare made her look like the Princess of Candyland.
Still, there were a few awful and misguided red-carpet attempts.
Lena Dunham should never wear yellow (isn't that so Paula Patton 2012, anyway?) whether Zac Posen designs it or not. The talented actress gave off an air that said she was above fashion, and as you know: When people try to make a fashion statement by not making a fashion statement, it's usually a bad fashion statement. Case in point.
As for Jennifer Lawrence's black-and-white Dior Haute Couture, I was not a fan. Neither was the Twitterverse. As people posted their own versions of the dress using toilet paper and black socks, it became the most memed dress of the night.
And, no, I can't tell you what Paula Patton was thinking - as many of you asked me Sunday on Twitter - with that Stephane Rolland Couture gown. I can say that being swallowed by a wavy whatchamacallit is never a good idea.
