She bought it at Barneys NYC so it has to be F/W 08 because Barneys hasn't ordered anything in gold hw since that time. But to be sure, check the white tag inside the pocket to see if it says 2008 3. Anthra GGH photographs very blue (see my avatar from the 2008 3 collection).
LOVE IT (and sweetie pie Merlin)! Let's see some close-up shots of the beautiful leather when you have a chance. Congrats on a fabulous new work!
