As you can see, it doesn't take that much work for a man to look casually sleek. Just opt for a duffle coat and white chinos and be sure you'll look incredibly stylish. Go ahead and throw a pair of dark brown leather chelsea boots into the mix for a hint of sophistication. When you're having one of those bleak fall days, sometimes only a cool look like this one can get you out the door in the morning. This is a modern but also age-appropriate pairing for older gentlemen.
