Many people who go out of their way to dress "richer" are running some kind of scam.

I'm not talking about actual rich people wearing expensive clothes, or even not-so-rich people dressing up nicely for a night out.

I'm talking about the guys who are always walking around in expensive clothes, and seem to be consistently bragging about their business and/or wealth. In these cases, the clothing is just a prop for the swindle.

On a related note, you should run away from anyone who routinely brags about how much money they have. Very few rich people actually do this. To them, having money is something they're used to, so it isn't something exciting that they brag about. In fact, they often avoid discussing their wealth, so as to not become a target for crime.

The ones bragging about money are typically the ones who are actually broke.

This doesn't apply to situations where someone is questioned or challenged about their wealth, and are defending themselves. I'm referring to those who brag out of nowhere that they are really rich.
