I have only glimpsed what OP is talking about; I never actually watch qvc presentations, only turn the channel if not interested.
I have switched to QVC when this line is on out of curiosity on the product presented.... I too have seen the deep cleavage and turned the channel because of that.
I know she's wearing certain clothes to show skin because that's the target of her line but it does turn me off to see all that.
HSN does a good job with skincare to me because I have seen hosts and vendors wearing off -shoulder tops to apply skin creams, lotions etc. Everyone knows decolletage areas to apply so seeing vendors showing so much, imo, is unnecessary. I have it, she has it. We all have it and put lotion on it. I don't need to see it to know to do it 🤨
