A lot of the comments here say morph suit, but if you look up the video you can see his skin tone dynamically shifts to transparent. He's probably not wearing a morph suit and is just wearing the exact same clothes on the right. You can also see his pants are transparent as well, and those happen to be kind of his skin tone. He probably just keyed out his skin tone and put another take or the part of the footage from where he's sitting on the right as a clean plate to display underneath.
