A white henley shirt and charcoal chinos are the kind of a never-failing casual combination that you so awfully need when you have no extra time. To add a little zing to this outfit, add a pair of brown leather casual boots to the mix. If it's one of those dreary fall afternoons, what better to cheer it up than a on-trend outfit like this one? This pairing demonstrates how to succeed in casual dressing as a gentleman in his 20s.
