The waist of these leggings fits smoothly over a mama tummy and is a great height in the rise for where it sits on the body. The shape is excellent around the bum and thighs. I love that the contrast colours are only visible from an exact side view and they appear black from the back. They are long in the legs and would work well for someone several inches taller than I (5'7") as well (they are excellent length for me because they're tapered enough at the bottom to fit properly at the ankle.). I slept in them the first evening I put them on because they are SO comfortable and silky feeling (like a baby seal's skin ;) ).
