I have white caviar.. just don't use it against dark cloth in summer time since it will stain slightly with time.. i only use mine when i wear white tshirt, or white jacket with jeans.. it looks perfect for the outfit!
jag.. the problem with lambskin that it scratches easily.. i had one in classic flap and it used to scratch when it rubs against belt or any jeans button on the side, etc.. I never herd of away to protect it.. my SA always recommend lambskin to me "more luxurious than any leather chanel made"!!
