What a beautiful collection. Congratulations--and enjoy them all.
I am amazed you could find 5 Birkins in one shopping trip. Every time I travel anywhere in the world (and I travel a lot), I go to the nearest Hermes store and I have only seen 2 Birkins in the past four years. Usually, the SA smiles or laughs when I ask for one.
Are there particular stores around the world that seem to have a good supply? Maybe I've just gone to all the wrong stores?
