My best friend and my coworkers tease me about how much my bags cost... I don't like telling people the cost of them, it's none of their business.
I've only had one complete stranger ask me the cost of the my bag, and that was after we had already been discussing it and he way overestimated the cost of it! But then, I carry a Damier speedy so it doesn't "scream" LV... should be getting my MC speedy tomorrow, we'll see how people react to that one lol.
I definately like the idea of turning it around on them and asking how much something of theirs cost!
