Heya, i just managed to grab one in Paris today, I only asked for the 30cm ones thou and they had 3. Gold, green and ebony. I grabbed the gold . Didn't check on the others sizes thou, I am presuming they do have some. Apparently a lot was sold out quicky right before xmas thou, so it must be dependent on season?
Congratulations! I think you're right about it being seasonal. I was at the Faubourg store on the 23rd and it was completely picked over (no Birkins, and only two Kellys that I saw), but I went to the George V store yesterday and they had two "normal" Birkins, two diamond birkins , a HAC and several Kellys. Granted, it's a different store, but I would imagine their inventory was depleted before Christmas as well. They must hold some back for after the holiday. Lucky you!
