I dont think QVC go on standard size charts. If they did all of the measurements accross the ranges would be the same. It depends on the cut, shape and design of the item, the inches have to accommodate how the style is supposed to look ie baggy or fitted. Hence I have sizes 10 to 16 in my wardrobe, depending on whether tge item is meant to be fitted or loose it varies, but they all fit. Sizing is insane, ignore it and just go by the measurements and the intended fit if the item.
