If you show me the heatstamp and underside of the zippers, I can make a better guess as to the year for you.I just got my first BV (authenticated here and by all available evidence authentic) - the seller told me she got the bag at an outlet in Florida (the price tag she included from the store also supports that). It is a black new gen Montaigne with suede lining, so it's probably from early to middle of this decade? Do you think it could be one of the not sold at the boutique ones despite black being a stock and not a seasonal color? Thank you!
I think the Montaigne has now been discontinued, so it's very possible that the bags at the outlet would be transfers from boutiques. I don't think they are making Montaignes "for outlet" but I can't confirm that with absolute certainty.
