Replica? You mean fake.
The point of expensive clothes, footwear, handbags and watches is that you are buying quality. The only reason I can see someone wanting to buy a fake is to pretend that they are someone they are not and give the impression that they can afford luxury goods when in reality they can't.
If attempting to suggest to the outside world that you are in a better financial position than you actually are makes you feel better then that's up to you. Am sure there are more positive and less misleading ways to do it though.
