I am 5'1 , 100lb, I ordered the small size , which turned out to be too tight for me. But I like the shape, fabric and contrast waist . The fabric is not cotton, it's a fabric that will not wrinkle, nor fading in color, always look like new. The shape is very flattering , make my legs look longer. I don't have any uncomfortable feelings when wearing it. The only complaint I have is that it is more like a straight leg pants instead of boot leg, at least , in my opinion. Anyway , I am exchanging the small size to a medium one. thanks.
