At the Paris Hermes store, I asked about ordering a birkin. Was asked which kind I wanted, and I gave a few choices, SA checked computer told me I could not order one color, but could order another color in 35. she wrote down my name and address. didn't show me any choices of leathers. told me we'd do everything by phone. I was so excited I didn't ask any questions, but now I'm wondering--how long will it take for my bag to come? if they're reallly custom made, why wasn't I shown a selection? why could I order one color combo and not another? any insight would be much appreciated.
