It was a Cinderella story at the 2010 Academy Awards, with lots of firsts and a few truly touching moments. Some stars dazzled, while others merely hurt the eyes. Who came up with the winning look for the night? And the award for Best Dressed goes to…

J-Lo’s form-fitting white gown was simple but extravagant at the same time, thanks to that over-the-top hip panel. Only Jennifer Lopez could wear Giogio Armani Prive’ so well. The sleek hairdo and tasteful touches of jewelry complete her elegant ensemble.

First-time Best Actress Nominee Gabourey Sidibe (Precious) was breathtaking in blue. This drapey, off-the-shoulder Marchesa number beautifully suited Sidibe’s full figure. Sparkling embellishments on the bodice add just enough bling.

Oscar queen Meryl Streep painted a classy portrait in this V-neck white frock, a very age-appropriate gown that oozes simple elegance. Streep’s attire was designed by Project Runway‘s Chris March.

Where’s Patricia Field when we need her? Sarah Jessica Parker, who’s no stranger to Worst Dressed lists, failed to impress in this simple Chanel number. The petite actress completely disappears inside the silky, cream-colored tube of fabric, which turns Parker’s curves into straight, boring lines.

Kate Winslet paired her simple Yves Saint Laurent gown with a stunning $2.5 million neckpiece from Tiffany & Co and stylish clutch. The glamorous ‘do and Winslet’s personal grace almost make this stiff, faux two piece gown work for her…almost.

Cameron Diaz was the epitome of glamor in this bold gold gown designed by Oscar de la Renta. The stunning, glittery gown and elegant sweep of hair were definite winners for Diaz.

First time Oscar nominee and winner Sandra Bullock was sleek and sexy in this gold number from Marchesa. Her simple hairstyle and accessories perfectly offset the highly-embellished gown. In more ways than one, Sandy was the big winner of the night.
