i bought two other pairs of these same pants in a small, and they were just barely too tight on my butt, but the zippers were fine. the zippers on the mediums get stuck at the waistband even though they’re not at all tight. the fabric is far more smooth than they look in the photos, with just enough sheen to show any and every simple in the skin. the front seam on the left leg of one pair is so twisted it’s embarrassing. :/
