For a look that's dapper and gasp-worthy, wear a brown plaid blazer and beige dress pants. And if you want to easily tone down your look with a pair of shoes, why not complement your getup with a pair of dark brown suede desert boots? As you can see here, this ensemble is a really nice idea, especially for unpredictable fall weather, when the mercury is falling. When it comes to fashion for 40-something gentlemen, this combination is ideal.
