I’m 5 feet tall, 115-117 lbs, 30 inch waist, 35 inch hips, and I purchased size small 25” length. I was worried about the fit but the fit around the waist and hips was good. I’m going to try the L’Original next so I can compare them. I’m going to try the shorter length because the fierce aren’t snug around the ankles. I feel better wearing the leggings. I’ve noticed I’m not as stiff when I stand up and that was becoming a problem. I’ve had them about two weeks and am wearing them daily so I want another pair so I don’t have to wash so many times.
