1. not sure where to post this, but how do i tell that a pair of sunglasses is authentic? are there any authentication experts for sunglasses here who can share some authentication tips?
  2. Usually to authenticate the glasses check the arms – on the inside of one arm it should say in tiny writing at the very end '(C) Christian Dior' and the other inside arm at the very end should say something like this: 'made in italy, diorstarshine (NAME OF MODEL) 1584LF 99-16 120 Optyl' hope that helps...not sure if it works with all models though.
