A dark green trenchcoat and charcoal dress pants are a polished getup that every modern gentleman should have in his closet. And if you wish to effortlessly play down this outfit with a pair of shoes, why not complete this outfit with a pair of brown suede desert boots? There's no nicer way to spice up a dreary autumn afternoon than a seriously stylish outfit like this one. No doubt, a fail-safe option when it comes to style for 50-year-old gentlemen.
