This whole Pajama trend actually started back in 2009 but Gigi Hadid and a few other starlets, like Kelly Rowland, just won't let it go! Just recently while in New York she wore this very chic Morgan Lane pajama set  with Stuart Weitzman shoes. And this isn't the first time she wore pajamas out in public, just have a look. Everyone seems to like wearing sleepwear as outerwear!
