Whether it was a quick change after the red carpet  or the first outfit of the night, the dresses at last night's Emmy afterparties were worthy of just as much accolade as those at the award show itself. Take Kate Mara, for instance — her white J. Mendel gown was sophisticated and glitzy, but once the festivities were over, the big guns came out. And by guns, we mean gams.
Others, like Joan Smalls and Malin Akerman, only required one dress — because theirs were that good. Think you've seen it all from the Emmys? Think again.
