I was browsing on the Bergdorf Goodman website and saw a possible price error for the Bleu Azur Clair City. It is labeled "Metallic Edge Classic Mini City Crossbody Bag, Light Blue" but dimensions and pictures lists it as a full sized regular City measuring at 10"x15"5.5" priced at $1325. It does ship directly from the store, so I'm not sure what they will send. If you do get a regular sized City, it would quite the cost savings at $500!
*Disclaimer: I am not sure what you will receive based on the description, it could be either the mini or regular but the description matches mostly with the regular sized City.
