You'll be surprised at how easy it is for any gent to get dressed like this. Just a navy overcoat married with black jeans. If not sure as to what to wear in the shoe department, go with brown leather brogue boots. When it's one of those gloomy fall days, what better to spice it up than a sharp ensemble like this one? Incredibly stylish, this ensemble is also age-appropriate for a 30-year-old.
