He might not be, but his portrayals on film are!
The fascination with James Bond is that he is a fictional character, crafted to be what every man 'aspires' to be. From his Aston, to his wristwatches, and his way with women. He also gets to be the hero which every man daydreams inside his head while typing reports in his office/cubicle/circus trailer/etc.
But I do agree with others. The fascination with a brand should be because of what the product brings to the table. I wouldn't mind having a Brioni suit. But I would never get one if I can get a bespoke suit for the same price. Why? Because no matter how nice the Brioni is made to fit, the bespoke was made to fit ME, down to the last deformity.
Still, to each his own:)
