Ok Im 54 and 240 lbs I ordered the biggest size and it fits my lower stomach in the first row of hooks my baby pooch if you will by my ribs tho I have to put it on the last row and its still loose the back of it is slightly longer than the front so if I pull it up so its not touching my butt then its not low enough in the front it doesnt fit in and is soft so thats a plus maybe Im just shaped funny or my baby pooch is just larger than ever right now after 2 kids and 2 c sections not sure if Id recommend this or order it again if probably look for a different one but if your lower stomach and rib area is the same size Id say its a good buy just my opinion
