first, most that complain about fashion either can't afford it or have no where to go to.
I don't care for high end denim, Levi's work for me. If I was a skinny ass fuck or obese dude I'd probably use it though to improve my game. My wife loves expensive jeans though as do her friends (one of the big items she is currently en route with back to Japan for a couple weeks).
I do like nice shirts though, I can find them down here in S. Florida much less than many have to pay for them though. Even on a discount I am probably spending more for T-shirts than some spend on their dress shirts.
Good clothes last a lot longer, you have to have the capital up front to carry that load though.
