Are the serial numbers on Chloe bags different for each bag? Or does each style have a serial #? Like say all paddingtons are 12-23-45(example). The reason I ask is I just bought a Chloe bag from a seller (a tPF member) and one of the pics showed a serial #. When looking at her feedback I see she sold the same style several months ago and one of the pics had the same serial number as the one I bought. I haven't gotten the bag yet. She is supposed to mail it tomorrow.
