I know that we're always talking about Birkins and Kellys as lasting bags -- and they are timeless, no doubt. But I wonder. How old is old, with a handbag, even if it's a beautiful quality handbag, like a Birkin or a Kelly? Everything does age, even if it's a Birkin or a Kelly. Everything does eventually need to be replaced or refurbished. Do you think a, say, 20 year old Birkin or Kelly would show its age and require reburbishment by Hermes? How old is old, is I guess what I'm asking. Is it worth it to buy older or vintage bags?
