Sizing and Fit:
These are such a beautiful fabric of denim, so soft and comfortable. And the shape and design is just fabulous. They are a generous fit, in that they are supposed to be slouchy in their fit. If you prefer a snugger but still comfortable fit I would size down. So for example I would be a good size 12 to 14 and I have plenty room in these, maybe they are a little big. Jess would be a size 20 in a jean and the size 18/20 fits her comfortably, if she wanted a snugger fit she could size down to the 16/18.
