18 of the most talked about looks at the Emmys

After every awards show, conversation revolves around two things: the biggest moments of the ceremony and who looked great on the red carpet.

While director Glenn Weiss' surprise proposal during his acceptance speech was by far one of the show's biggest highlights, which star nabbed the award for best dressed remains debatable.

Jessica Biel, who nabbed a nomination for her work on "The Sinner," attended the ceremony in a Ralph & Russo Couture gown that critics seemed to love. She accessorized with Harry Winston jewels, a Tyler Ellis clutch -- and of course, her husband, Justin Timberlake, who wore a traditional black tuxedo.
