Just received my jeans last week and I really love them. I am 5'2" and the jeans were the right length. I assumed they would be too long. Also thought I'd need the 1x, but these run a little big. An XL would have been fine. Take the manufacturer's advice and wash the jeans first because the indigo coloring will rub off on your hands and other stuff even after the first wash. Otherwise, I am looking forward to my next pair.
I got my pair on clearance at my Target store - someone had bought them online and returned them. I debated whether I should buy them because they were a Large, which was stated to fit a 14-16. I am a 12, but decided to give them a shot anyway and just return if they were too big. They fit perfectly, so they definitely run a size small. But oh my gosh, do I love these. They are soft and comfortable and honest to god look like real jeans. The only time you can tell they aren't really denim is if you're looking right up close. I'm not going to lie, there's no way in heck I'll be telling people I'm wearing Pajama Jeans, but I'm also planning on buying another pair and wearing these in my every day life, not just at home!
