I am a plus sized woman and I typed in the size I was looking for.  This came up for a very reasonable price in the size I was looking for (3X).  When it arrived, it was in an envelope so I had to open it.  After I opened it I saw that the size was only a 1X.  It felt pretty stretchy so I tried it on.  There is no way this thing would fit a heavily endowed woman such as myself, even if I lost enough weight for it to fit (which I am working on).

Then when I contacted the seller about the false sizing description, I was basically told that because I had opened the package, they could not accept the return.
