The stars shone at the 2012 SAG Awards at the Shrine Auditorium on Sunday (Jan. 29) in Los Angeles. The red carpet was filled with elegant and sophisticated outfits, and although the celebs weren’t as glamorous as they were at the 2012 Golden Globes, we still saw some amazing fashion choices.

Here are 13 actresses that looked beautiful on Sunday night, with gowns signed by the biggest names in the industry: Alexander McQueen, Marchesa, Givenchy, Oscar de la Renta and many others.

Emma Stone in Alexander McQueen

The actress from ‘The Help’ looked beautiful in a black Alexander McQueen exploding lace bustier dress, clutch, shoes, and Tiffany & Co. diamond earrings by Paloma Picasso.

Octavia Spencer in Tadashi Shoji

I’m a big fan of Octavia, and her looks often surprise me – she always chooses appropriate, but glamorous outfits and shines on the red carpet. This time she opted for a Tadashi Shoji gown.

Viola Davis in Marchesa

Viola Davis was one of the best dressed celebrities from the 2012 SAG Awards, looking beautiful in a custom Marchesa graceful gown. Her hair seemed a little messy though.

Zoe Saldana in Givenchy

Zoe Saldana rarely disappoints on the red carpet. For the 2012 SAG Awards, the actress chose a dress from the Givenchy Couture Spring 2012 collection. Her shoe choice wasn’t as good: her beige and lace peeps didn’t quite match her couture gown.

Sofia Vergara in Marchesa

Sofia Vergara didn’t risk it at the 2012 SAG Awards. She wore a beautiful Marchesa custom strapless gown, accessorized with Lorraine Schwartz jewelry and a Thale Blanc clutch. Her choice was predictable, but she still looked amazing.

Jessica Chastain in Calvin Klein

Jessica wore a blue Calvin Klein Collection dress, simple, but interesting. She accessorized her look with Harry Winston jewels.

Glenn Close in Zac Posen

Elegant as always, Glenn Close wore a Zac Posen black tiered taffeta and tulle gown.

Lea Michele in Atelier Versace

This one is my personal favorite from the 2012 SAG Awards red carpet. The actress opted for a gorgeous Atelier Versace Fall 2010 gown.

Emily Blunt in Oscar de la Renta

Emily shined on the red carpet in a beautiful green dress from the Oscar de la Renta Resort 2012 collection. A Swarovski clutch and Jimmy Choo sandals accessorized her look.

Michelle Williams in Valentino

Michelle Williams was Lady in red at the 2012 SAG Awards, in an asymmetrical Valentino gown. Fred Leighton jewels completed her look.

Angelina Jolie in Jenny Packham

After looking simply amazing at the 2012 Golden Globes, Jolie took our breath away again with a black liquid metallic gown designed by Jenny Packham. I’m wondering what she’s going to wear at the Oscars.

Kaley Cuoco in Romona Keveza

Kaley looked like a fairy princess on the red carpet, in a blue Romona Keveza Spring 2012 gown. Her hair also matched her look perfectly.

Stacy Keibler in Marchesa

George Clooney’s date looked dashing in a black lace Marchesa dress. She and Clooney make a stylish couple, don’t you think? Brad and Angelina have some serious competition.
