A grey plaid blazer and khaki chinos combined together are a wonderful match. For a truly modern on and off-duty mix, complete your ensemble with brown suede chelsea boots. When it's one of those gloomy fall afternoons, what better to cheer it up than a on-trend ensemble like this one? As a guy in his 30s, you want to start dressing in a classier manner. That's when getups like this are a surefire option.
