At what point does it become pretty obvious someone is wearing an older version of classic flap? I noticed classic flaps from 10+ years back look kind of less puffy, though I'm not sure how much of it is age and how much is the change in style. Can you guys tell if a bag is 10, or 5 years old (assuming it's in very good condition, so regarding the style of the bag only)? Is it viewed any differently than a "current generation" classic flap?
