I just tried on the cobalt cabat in the large, it was STUNNING! BUT it's too large for me so I am waiting on the medium. i also tried on the Copper Rame, it was absolutely AMAZING! Sadly, if I AM GOING TO SPEND $10K, IT WILL BE ON ANOTHER BIRKIN. It was jsut soooooo expensive!
if anyone is looking for the cobalt in large, PM me and i can give you the details!
