I guess I would consider my zipped key holder and my pochette accessoires original model to be vintage, and they’re both 25 years old. To me, 25 years seems like a good point at which something becomes vintage. Honestly though, with the quality of some goods being produced currently (and not just LV) it’s frightening to think that people might at some point in the future refer to them as vintage, if they’ve actually lasted that long. The term won’t hold quite the same meaning, that’s for sure.
