On the other hand - if you've got the Armani suit, the Tag Heuer or Rolex, and drive the Porsche, you can only be 'faking' so much; obviously you've had some financial success.
Not really - the suit and the watch would fit onto a fairly normal credit card, for example. You'd be a fool to go into debt for them, of course, but people do, status symbols, even misguided ones, can be powerful lures. Rolex and TAG in particular are now almost anti-brands for that reason (same with Louis Vuitton luggage, Porsche, Burberry, etc).
The guys who signal to each other with these accessories are subtle and understated - their messages are intended only for others of their type. Anything a rapper would wear is out! Think Pierce Brosnan in Thomas Crowne or James Bond. He's a actor who is "faking it", playing the role, and doing that on screen takes a wardrobe professional who studies this full-time and the budget to spend not $2000 but $20,000 on a suit (really, that's what Brioni costs, and what the production spent) and I'm sure there are real "upper class" people who glance at Bond and spot all the little mistakes straight away.
