11. Know your dryer cycles
It may be tempting to just run everything through the regular high-heat dry cycle, but that's a good way to rapidly wear out your duds. Instead, embrace all your options. Often the best choice is "Permanent Press," which runs a medium heat cycle followed by a cool-down period at the end that helps reduce wrinkling. When in doubt, skip the dryer entirely and let things air dry.
12. Unbutton your buttons
Whether it's an Oxford or a pair of chinos, make sure buttons aren't secured before beginning a load. Otherwise you risk prematurely weakening their threading as they're tossed to and fro in the machine.
