I have a Caviar Jumbo SHW and a Lamb m/l GHW. Since the m/l is a bit small and I'm scared of lambskin (lol), my Jumbo is my "everyday" and my m/l is more "occasionaly" bag. Works perfectly for me.
I have a black caviar jumbo w/shw and a black maxi w/ghw. Would also love to have a black lambskin with gold or silver hw too. Will get it one day, I'm sure. I LOVE black Chanels!
I have m/l AND Jumbo in black caviar w/ SH. I wonder a lot if I should have got a lambskin one or gold hardware, but at the end of the day this combo works best for me!
I know some people buy both to serve its own purpose... I have just bought one and if I will be fortunate to buy another one... it will be in different color... red, beige, white, maybe even purple! The list is endless....
