I just bought this Dior Gaucho on eBay and am not sure if I should keep this bag. I had the bag authenticated at my local Dior boutique in SF and it's an authentic bag. But upon closer inspection today, I noticed the bag is a bit dirty (especially at the bottom) and on the tan leather trim. There are also specks of white on the off-white leather. I paid $699 plus shipping for this bag and the seller does offer a 7-day return policy. Is this bag a good bargain or should I return it? I'm not a Dior expert, so any suggestion will be appreciated! Thanks!!
