Thank you for such a quick reply. The person I purchased from is not answering me. It was on Vestiaire and was authenticated so nothing to worry about there. I wonder if I called a BV store could they tell me!The only way to know is by the serial number, and Bottega Veneta has to be the one who tells you. I don’t know what their warranty is - you might have to provide proof of purchase from an authorized retailer; maybe you can get that from the original owner?
