Cheap designer handbags

Ok so this seems to be happening more and more lately. Designer bags that look very alike. This time it is a bag from Jimmy choo and Marc Jacobs. Now i have to say that they are not exactly the same but there are some very big similarities in them. One difference that i am sure you are going to notice is the Price as the Marc Jacobs is around £995 and the Jimmy choo only around £395. Now that is quite a difference in my opinion. Still is does make you think, are the top designers looking more and more at each others work?
