I recently fell in love with the Marc Jacobs Natasha bag after seeing it IRL. I've been checking on ebay for some deals on the bag and noticed that some sellers include "Classic" in the bag's name while others do not. Also, some Natashas have the black and white interior while the interior of some other Natashas is the same color as the exterior. So is there a difference between classic and non-classic Natashas? And does the interior of the bag play any part in whether it's classic? Thanks so much for any information.
