I needed a body shaper/smoother to wear underneath a very light fabric and this item did the job. According to the sizing I needed either a 3XL or 4XL (Im a size 16-18 bottom). The size I purchased only went up to XL-XXL, the fit was not constricting at all, it was easy to put on and to take off, and I did not look like I was wearing a girdle at the waist (no muffin top).
