These are super comfortable and have wonderful pockets, too. The waistline is very stretchy, so it fits a wide variety of sizes. I returned a large and got a medium, and I am 5'4" 155 lbs and they are even a little loose. I could probably get a small and they would fit, but be more like a fitted style, and I didn't want that. They are loose enough around the waist that I do pull them up occasionally, but they feel like pajama pants and are professional and stylish.
