Disappointing purchase

To tell you the truth I was disappointed with my purchase of a Flexees panty girdle.. I weigh 139 lbs. and assuming that imported goods tend to run smaller, as I find all the time.I ordered a size 2X, thinking that would be more than adequate. It was anything but. Much too tight and I couldn't get it all the way on. I am housebound and can't get out so have to depend on buying on-line.
