I just ordered my first Chanel, its pictured below. Can someone explain to me the various types of leathers, I know what patent is, but not sure about mine which is described as antiqued quilted calf leather, or caviar. Is one kind of leather more expensive in general than the others. Also, I've been reading prior posts and noticed that there are alot of warnings about patent white bags with discoloration and or color transfer. Do you think this will be a problem with the one I just purchased. They had it in black, but I just fell in love with the ivory.
