3. You treat your tailor like your doctor.
You call up your tailor fifteen minutes before he closes because you have an emergency—you just copped some Brunello Cucinelli pants at a sample sale and need them hemmed before you go out for drinks tonight. Good thing you guys are on a first-name basis. Your tailor probably knows more about you than your actual family, like your measurements. And while you're hesitant about going to the doctor for a simple check-up, you won't hesitate to see your tailor about fixing a jacket sleeve that's a quarter-inch too long.
