"Yes, your lucky suit may have landed you the dream job 15 years ago, but a lot changes in 15 years," says Amy Acton, founder of Acton Style Group. Not just what's in style, but your body, too. "Odds are, it no longer fits quite the way it used to." And when it comes to dress, "fit across the board is they key as you get older."

"Dressing well is a form of good manners," Tom Ford, the iconic designer—and the menswear world's best-dressed man—once said. If his point is true (it is), then a lot of guys over 40 are in serious need of an etiquette lesson. Maintaining your appearance is a sign of respect—not just for yourself, but for all of the people you interact with on a daily basis. It shows that you care.
