My first I no longer have. I don't even have my second, third, or fourth. What I can show you is the oldest bag I have in my collection. It's a D&B with the duck. The oldest accessory I have is a Gucci wallet that is 25 years old, and it's still in great shape. Here are pics of the bag and the wallet.
My first real designer bag is at my parents' house. It is a very simple Gucci that my dad bought me for my 17th birthday (18 years ago!) It was one ofthe cheapest one that they had, but I loved that purse!
