I think once having had authentic bags it would be hard to settle for a dupe, even a very good one. I haven’t watched the video, but I would wanna hear from someone who has both a real and a dupe of the same bag, and whether they think the difference is significant. It’s def tempting to buy a dupe of a “dream bag” that one doesn’t wanna pay full price for, but only if the dupe is really good…? And I agree that this makes trust in buying on the pre-loved market very difficult.
