I would take one size larger. It seemed to get smaller and narrower. So we couldn't even use it. Already in a used gift box, I took off the tag and already washed it. The fabric looks dense, the quality is good. It probably wears very well. Also tighter than it looks around the ankle and calf which is odd for such a thick canvas fabric (compared to sweatpants material).
