There are very few shops I go in and think, I love everything or could wear everything. I agree with most of what people say about QVC fashion. I look at some items and think "you cannot be serious!".I also think is is heavily orientated towards frumpy older women.
Having said that, some ranges have the occasional gem and it's just a question of knowing how to put an outfit together and knowing what suits you. I don't think I dress young for my age but I'm not going to settle for a pleated skirt and twin-set - EVER! I love clothes and my outfits are often commented on (and no, they're not being sarcastic) and most of them are based around a QVC piece.
I like some of Kim&Co - not the garish colour combinations or the ghastly scarlet trousers or similar. They don't cling, are cut high on the armholes (I mostly wear sleeveless) and drape beautifully on my less than perfect figure. I have favourite jackets from Indigo Moon and even a couple from Quacker - a show so embarrassing I can't watch.
I adore Diane Gilman jeans, though I always have to have them taken up, but they are the most flattering ones I've ever had. I have a couple of Ronnie Nicole dresses which are classically lovely, one of which I purchased on ebay.
I have never been tempted by anything from Michele Hope, Renee Marten or any of the other brands that cater exclusively for Grannies (IMO). However QVC has introduced me to brands I would never have known about, even if it's just to know to avoid them....
