Stretchy “Jeans”

I don’t believe this is actual denim but they look like jeans. 95 cotton. 5 Lycra spandex. If I hadn’t stated this you probably would never have noticed it b/c it’s so faint but when I took these out to post I noticed some staining around the waistband that I can only attribute to the fact that I used to use the body lotion that built a tan over time. I washed them in hot water with Clorox2 and it got out 99.9%. 17” waistband closed and lying flat unstretched. Seat 20-21”. 30 1/2” inseam. Cream
