Cersei Lannister

Oh, sure, there are some actors and actresses who look exactly like their TV alter egos. (Hi, Zooey Deschanel!) But there are some who owe a big debt to the makeup, hair, and wardrobe departments (and whoever makes Jon Hamm shave on Mad Men). Good acting is one thing, but a good costume can make or break a character. Click through for all the actors we spotted at the Emmys who undergo some amazing transformations for our viewing pleasure every week.

Warning: Spoilers ahead! The most momentous thing (from a fashion perspective) to happen in the last episode--which passed with very little commentary by the characters--is that Brienne of Tarth wore a dress. A pink dress lined with fur at the bosom. This is kind of a big deal for someone who's always wearing armor. We got all the scoop from costume designer Michele Clapton about what she was thinking when she designed that dress and how she wanted Brienne to look. More this way...

Warning: Many spoilers ahead! This might have been the nakedest episode of Game of Thrones yet. And that's saying a lot. It's sort of hard to talk about the fashion when no one was wearing any clothes, but we'll try our best.
