I've been out of the Chanel loop for awhile and was wondering if someone could explain to me exactly what a reissue is? What is the difference between the sizes (2.5, 2.7, etc). and how are the reissues different from the Jumbo classics? I've been seeing some gorgeous pics of the larger chanels, usually labeled as either reissue or large/jumbo, but am unsure which is which. I particularly love the dark grey one that Courtney Cox has and the metallic bronze one on Jessica Alba (both have the newer chain), but when I called chanel asking about them, they said they are already sold out because they are from the last season. Please enlighten me!
