Ok...depends on the bag.
OP: If you truly love something, buy it, wear it. Whatever. Who cares where the bag came from? Unless you care about what some snobby clerk says. Most of those people can't afford the bags they sell. Most of the DB bags sold on the Q are the same. The TSVs are bound to have issues.
You know, I have carried the "Q specials" and received compliments on them. Other people buy them, too. If I think something is shoddy, looks ugly, I don't buy it.
The bottom line is you should be buying what you like and not worrying if some else likes it or is "impressed" with you. Life is too short.
Where I'm from, Dooney isn't a big deal: LV, Prada and Chanel are. Then they check to see if you are carrying a fake.
