some Marc Jacobs are in leather. and his older bags are lined in suede
Do you mean only leather or leather as in leather and suede?
Hermes bags and my Chanel reissue camera bag is lined in leather. I actually prefer a bag lined in leather.
It could be just me but I think when they are lined in leather they are heavier. With the exception of my Chanel reissue, but that is just the perfect bag... it can do no wrong!
