These are the first spanx that I have ever worn and they performed as I hoped.  The bump section could have a higher band but that is what you get with the one length fits all sort of option.  I found that my pre-pregnancy height/weight workded for sizing. My lower legs did swell up mightily when I wore these, which might have something to do with my thighs and behind being squeezed in, but that isn't the spanx fault.  It is something to watch out for.  I might switch to the pantyhose for this reason.
