Certain trouser styles do fit certain body shapes better so the FB poster was correct in one sense, QVC will already sell them, they just need the presenters / stylists to give that information when discussing items. That's the difference between a proper stylist who understands the fit of a garment and one that thinks it's all about what the latest colours are. Body shape is just as important as size really. I know one shop that used to have "trouser days" once or twice a year where they would get in many different styles of trousers and offer fit advice.
