These are corduroy pants I purchased from Cecile before. Even though it's only 1% polyurethane, the stretch makes a difference. I didn't wear them much because they didn't suit me, but the fabric's nature has caused some whitening, like at the knees. I read reviews saying they run large, so I chose S even though I usually wear M. They are big, so please refer to the actual measurements. The back of the waist is elastic. There are details on the website, and the reviews are good. They are warm and stretchy, so how about wearing them at home, for one-mile errands, outdoor activities, or dog walking?
