Hello,
I have a couple of the Kate Spade bags and really like them.
They have held up well.
I found mine at TJM, and even though the styles they get may be last season, they are still classic and easy to carry.
I've seen Rebecca Minkoff items (purses and accessories) in there as well.
Quality seems ok, but I like the KS better. The pieces I've seen. KS has a better feel and more refined look.
My 2 cents.
