TBH, as with other brands in the clothing lines, I believe that the TSV's are skimped during manufacture. I can't believe they are going to turn out masses of stock to be sold at a low price at the same quality as those you might find in a shop. If JR finds them roomy round her calves, is it possible she was wearing her own pair purchased elsewhere? This is only my opinion and I could be wrong, but other TSV items I've bought in the past have definitely been an inferior quality to 'regular' stock. Having said that, I find Emu's don't fit me very well. I much prefer the fit of Uggs.
TBH that has never occured to me....maybe I am very naive, My love affair with QVC is slowly waning. I seem to spend more money sending this back these days , god knows how much it has cost me!
