QVC loses a big selling opportunity by not having the women hosts wearing QVC clothing when selling QVC clothing lines. If only tall models, the plus models or a really petite model is wearing the clothing, it's not particular representative of someone who is of average height or average build.
I do think that the hosts send out a not so subliminal message when they are wearing non QVC clothing that the clothes aren't good enough for them.
Those QVC stylists who put the hosts in non QVC clothing aren't doing their jobs either. The viewers aren't stupid and can easily tell or find out most of the time what the brand is and where the clothing comes from.
