I found a vintage Burberry trench coat at the thrift store today for a cool $20. It seems authentic, but the inner plaid design is not the trademark Burberry plaid. The vast majority of vintage Burberry trench coats I've seen have the trademark red, black and beige Burberry plaid lining. The vintage tags seem correct (I.e. The size tag behind the main label I've seen in vintage versions). And the polyester lined sleeves seem correct. Any Burberry experts who can confirm?
