I have a version of the Birkin, asa posted...Raisin boxcalf Vibrato, but I don't have a picture of it available.
Is that your Birkin asa? Just wondering, because if so, we are almost Vibrato Birkin twins....although I do realize every Vibrato pattern is unique.
I love the Vibrato blues, but for a bag, I think that the raisin was my first choice...however given their rarity, I probably would have taken any pleasing color that I could find.
We are twins! It's so light and quite beautiful up close. I, too, love the blues. If I am lucky enough to chance upon one, I'd love it.
