These jeans are of stretchy material and super comfy, yet stylish! I love them. I didn't go based the measurements, which it was a good thing. If I had followed the hip and waist measurements, the jeans would have been too big. My hips are 42 and my waist is 30 at 2 months postpartum. Size 11 was fine for me, which would be about a Medium. The  color is True.
