Having plowed through most but not all of this thread, I'm thinking that the only people who can REALLY answer the question is someone who actually carries/d one. A few pp have admitted to doing so and explained why.
I saw a woman the other day carrying an AWFUL
Coach fake--the "C"s were actually "G"s-- and the handles/trim were clearly vinyl. Maybe a child or friend gave it to her as a gift. Maybe she bought it knowing it was a fake, but thinking it looked good. Maybe she didn't know that it was a knockoff of a real bag and just liked it. I was on line behind her, bored, and these thoughts just ran through my head.
But of course I couldn't ask her, bc that would have been rude beyond belief.
