Yahoo! Style editor-in-chief Joe Zee breaks down his fashion do's and don'ts from the SAG Awards.

Brie Larson: The 26-year-old Room star's glammed-up look was Zee's favorite of the night -- not bad for a last-minute decision. "That Versace dress was on the Paris runways five days before the awards," he said of her sexy, blue number.

Sofia Vergara: "The best thing about her in this custom Vera Wang dress is that she knows exactly what works for her," Zee said. "If it ain't broke, don't fix it."

Eva Longoria: The 40-year-old Telenovela star stunned in a Julien Macdonald gown that Zee called a "hello, goodbye" dress. "It's like 'Hello!' in the front, but it's like, 'Goodbye!' when she turns around!" Zee gushed.

Kaley Cuoco: "Can we talk about a revenge body in a divorce dress?" Zee said of the newly-single Big Bang Theory star, who wore a revealing off-the-shoulder Romona Keveza dress. "She looked phenomenal!"

Demi Moore: "A lot of people actually didn't love that dress she wore. It was ruffled and buttoned all the way up, but it's actually a Zac Posen dress from the back of her closet from 2002," Zee said. "Shopping your closet? I love it!"

Nicole Kidman: One of the few fashion misses of the night came from the Oscar winner, who wore a ruffled, multi-colored Gucci number. Zee offered some constructive tips that would have saved her red-carpet look. "I actually would have made it a little more sophisticated by putting her hair up. That would have changed the entire look of the dress." Zee also would have simplified the look further by removing the ruffles and changing the color to emerald: "Nicole, call me!"
