The background, clothing and especially other people in the image are still a dead giveaway that it's not a real person. It's kind of weird how the algorithm borks something relatively simple as the texture of clothing.
I don't know but I imagine somebody might want to generate an algorithm that puts random clothes on people. There's so much money going on in the fashion industry and beautifying. If you can see how a new shirt fits on an existing person you can also fit a shirt on a fake person right?
