Oscar Fashion: Winners & sinners (hint: it was a good night for Sandra Bullock)

Oscar fashion has become so predictable. But this year, a number of actresses took some calculated chances with gowns that incorporated architectural designs, bold colors, and high-tech fabrics. The result: The most refreshing red carpet styles I've seen in years. There was a lot to like, along with a few  "What were they thinking?" moments that make watching the Oscars so much fun. Here are our fashion Winners & Sinners. WINNER: Sandra Bullock looks like an Oscar statue in a gold Marchesa gown with intricate floral embroidery on the bodice and shoulder. It would have been perfect if her hairstyle weren't so casual and her lips so red.

WINNER: It was a good night for full-figured women (Queen Latifah and Mo'Nique looked great on the red carpet) but no one looked better than Gabourey Sidibe, in a deep blue gown with silver beading by Marchesa. Sidibe was clearly having the time of her life in a gown she clearly felt comfortable in. "If fashion were porn, this dress would be the money shot," she told the E! Channel's Ryan Seacreast.

SINNER: High fashion rarely works on the red carpet. Case in point: Diane Kruger (with director Quintin Tarantino) in a Chanel gown with black bands at the neck, waist, and knees. But she still looks a better than he does.

WINNER: Sarah Jessica Parker (with husband Matthew Broderick)  can do no wrong. Her retro Chanel Couture gown — accented with a '60s-style bun — looks timeless.

SINNER: Love the color of Charlize Theron's gown designed by John Galliano for Dior. Love the train. Hate the squiggles on the breasts.

WINNER: Anna Kendrick said she picked the soft pink gown designed by Elie Saab at the last minute. Good choice.

SINNER: "I thought I would be Marilyn Monroe-esque today," Miley Cyrus said. Looks more like she was (unsuccessfully) trying to channel Madonna instead in a bustier gown by Jenny Packham.

WINNER & SINNER:  An eye-popping magenta color and cascading fan pleats made Verna Farmiga's  gown by Marchesa a real standout on the red carpet. But it looked better from the front.

WINNER: Mo'Nique's asymetrical Tadashi Shoji gown was a bit understated for her big night, but the color is electric. (She's with husband, Sidney Hicks.) Nice touch: She wore a gardenia in her hair in tribute to Hattie McDaniel.

WINNER: High-tech fabric molded at the bodice gave Amanda Seyfried's Armani Prive princess gown a modern sensibility.

WINNER & SINNER: From the waist up, Zoe Saldana's Givenchy gown  was the evening's best. From the waist down, it looked like grandma's  throw rug.

WINNER: Tina Fey, in a sparkly black one-shoulder gown by Michael Kors, and Elizabeth Banks, in gray Versace, proved that muted colors can have some pizzazz.

WINNER: Nobody does glamour better than Jennifer Lopez, in Armani Prive with an origami-like side train, and Demi Moore, whose Atelier Versace gown was slit to show a bit of leg when she walked (that was one of the evening's big fashion trends).

WINNER: Penelope Cruz and Sigourney Weaver looked elegant - if not exactly memorable - in shades of red.

WINNER: Mariah Carey (with hubby Nick Cannon) has had her share of fashion disasters. But she got it right on Oscar night in a Valentino gown that would have been too tame without the slit that showed some leg.

WINNER: We just threw in a photo of George Clooney for a little eye candy. But he looks a lot happier here on the red carpet than he did during the Oscar telecast.
