I've heard this crap time and time again, and I have to wonder if it seriously works. I mean...long term. Besides the obvious fact that "Money will get ladies, but you have to show the ladies that you have it." is basically treating women like whores, the women that accept this pretty much are, in fact, materialistic whores...so I guess they do get what they deserve.
Sorry, but there are plenty of "real" women out there who don't give a crap about this sort of stuff. I know. I have one, and she loves me for being me, not for trying to pretend I'm some playboy wannabe. I am and will always been a jeans/t-shirt person, and I always will be. If a person of the opposite sex is too vain to accept that, then well, they're not good enough for me.
Spending $500 on single outfits is about the stupidest thing I have ever heard of, and I know rich people who spend more than that on just a single piece of their outfits. I don't understand, nor will I ever understand, why. But whatever, it's their money. They can waste it how they want.
Honestly though, if you need $500 outfits and fancy BMW's or whatever to get a girl, then you're obviously doing something wrong. I'd re-think your strategy because sooner or later you're going to need to have a conversation with your date. No money, outfit, or fancy car will be able to help with that.
