The patent leathers are wonderful bags. I know that some of her MACs from the winter like black, neon yellow and hot pink were PVC bags, not patent. Patents were red, black, charcoal, purple, and navy (the latter is hard to find).
Black was actually not patent but PVC (from Spring 2009). I unfortunately learned this the hard and personal way :,-(
the quilted patent bags are patent leather though and pvc!
