The Screen Actors Guild Awards are generally considered a trial run for the Oscars. Held in Santa Monica, the awards are usually more casual than the Academy Awards, which means that the actresses are a little more relaxed in their style choices. But our SAG Awards 2013 best-dressed list shows that top-notch style isn't necessarily synonymous with "serious." To wit: The bright pops of color amidst the sleek column dresses in black and white. Our favorites included Marion Cotillard in Dior Couture, Kerry Washington in Rodarte and Jessica Lange in J. Mendel.

Check out our picks for the best-dressed actresses at the 2013 SAG Awards, and then head over to our worst-dressed list for a laugh.
