When people talk about genuine fakes there are such thing, I remember my brother being in the rag trade many years ago, he told me what would happen is, they would agree a design with a major company to supply so many thousand dresses, they would then purchase the material, negotiate a price with a factory to make them, the factory would always be able to make more with the material than they agreed. The left over were then sold to market traders etc as genuine fakes. I would'nt be surprised if this is still going on and the same with handbags. The chances are the fake handbag which is expensive is made in the same factory by the same people as the one that cost 10 times as much.
