I purchased a Damier trousse on eBay. I was using it today and someone asked where I got it from, I said, "I got it on eBay from a reputable seller." She looked puzzled and said, "Don't they sell fakes? How do you know it's real?" Then I went on to describe tpf and about the Authentic thread. She didn't seemed to believe me. Anyways, what's a tactful way of responding to people about your 2nd hand/gently used LV, when they ask, "Where did you get your lovely LV bag?" Just curious...thanks!
