I'm a big fan of the Jige clutch too. I have a vintage Jige in black calf box which I believe to be the GM size. I had a smaller PM one but let it go because it was a bit small for me, I can't even travel light for an evening out. The GM is a good size for me, albeit perhaps a bit big for evening for most girls, because I can use it for evening and for daytime as it is large enough to take an A4 pad/agenda for business. I normally wear them as handheld or just tucked under my shoulder.
For anyone who is a Sex in the City fan, I've seen Miranda with a Jige or two in the later series which I didn't see the first/second time round.
Also when I was snooping around Goyard recently another customer had the most glorious Cognac (?) Jige but I was trying not to spy too much or go to green!
