Just when you thought you were done with the rules for wearing a suit, we come up with another five. We want you to look your best, so we’re giving you this advice.
1) Unbutton before sitting. Seriously. It doesn’t matter who you are or what your waistline is. When you sit down, your middle is going to expand past what it was when you were standing. If you sit with a buttoned jacket, you run the risk of something tearing or buttons being turned into shrapnel.
2) Speaking of buttons, in a two button jacket the top button should be just at your navel. If you have a three-button suit, the middle button should be just at your navel.
