5. Thou Shalt Not Impulse Buy
Things like suits and designer pieces are an investment, with hefty price tags to match. It's also no secret that most people aren't made of money. If you happen to have a trust fund and can spend freely at Barneys or Savile Row, then by all means, live that life. But if you're like the majority of the population who occasionally buys gear, then purchase carefully. The key is to buy things you'll get a lot of wear out of, and will dig for more than just one season. That's what separates menswear from womenswear, it's driven by construction, fit, and timelessness rather than trends.
