I'm in two minds about these.
I absolutely think that they are ridiculously overpriced! £80 for a vinyl bag is total madness! Many of them I don't like, as they are a bit too bling bling for me, but there are one or two I don't mind, but wouldn't buy due to the price.
I must admit I did buy the signature bag (which is made of thick jaquard type fabric, NOT plastic) a while back though and I really like it and have had many a compliment (although I did take off the sparkly dangly bag charm!).
There is the odd one or two I've liked in TK MAxx for a much more realistic price, but QVC are having a laugh at the prices they want to charge.
But it's all personal taste. Personally I detest Kiplings as I think they look very "mumsy" and wouldn't want to go around with a furry monkey on my bag, and feel they are very overpriced for thin nylon although I don't mind the leather bags.
Most ranges have something to like and dislike. But the KVZ prices are crazy on QVC!
