While Lea Michele and Stacy Keibler played it safe at the 18th Annual Screen Actor's Guild Awards in Los Angeles Sunday, other stars opted for more daring dresses and bold accessories.


My Week With Marilyn star Michelle Williams, 31, wowed in a red lace Valentino gown with Roger Vivier "Cage" sandals, a Lanvin bag and Fred Leighton featuring Forevermark jewels.

Zoe Saldana, 33, went high fashion in a white silk organza Givenchy Haute Couture by Riccardo Tisci gown with Tiffany and Co. jewels. 

Angelina Jolie, 36, revealed more skin than usual in a black draped front (and nearly backless!) Jenny Packham gown with vintage House of Lavande jewels, Gucci shoes and a Louis Vuitton purse.

"I wanted to be comfortable," she revealed on the red carpet. "I always liked vintage jewelry. I don't often wear it."

Glee's Heather Morris, 24, was among the stars whose look wasn't as well-received. The actress wore a black leather-trimmed Masai Payan dress with a sheer skirt, Glynneth B jewels, and silver Giuseppe Zanotti shoes.

Another big risk-raker: Rose Byrne, who wore an embroidered Elie Saab jumpsuit with structured shoulders.

"I love a jumpsuit. I'm a big, big fan," the 32-year-old Bridesmaids actress told E! News. "I found this one and I was like, 'You know what? I'm going to rock it tonight.'"
