The biggest stars in Hollywood came out Sunday night for the 21st annual Screen Actors Guild Awards. The event, held at the Shrine Auditorium in Los Angeles, celebrated 2014's outstanding performances in film and primetime television.

Sixty-five actors were nominated, but only 13 people walked away with the Actorstatuette. However, not all the focus was on the SAG stage. Here are the best and worst dressed stars that caught our attention on the 2015 SAG Awards red carpet:

Best Dressed

Lupita Nyongo

Absolutely stunning! Lupita Nyongo was on hand at the Screen Actors Guild Awards to present an award alongside Jared Leto. The 31-year-old wore a striped watercolor Elie Saab gown with long sleeves and a deep V-neck cut. Nyongo gets double points for donning a shorter version of the dress for the Weinstein after-party.

Kaley Cuoco

Kaley Cuoco of The Big Bang Theory kept her SAG red carpet look simple yet elegant. Her red Romona Keveza gown hugged her svelte frame and her Forevermark diamonds were the perfect accessory to look like Hollywood royalty.

Melissa Rauch

Kaley Cuoco wasnt the only Big Bang Theory star turning heads. All eyes were on Melissa Rauch in a color block strapless Pamella Roland gown.

Maisie Williams
