A navy suit looks so refined when married with a beige trenchcoat for an ensemble worthy of a real gent. Not sure how to round off? Introduce a pair of dark brown leather loafers to the mix for a more relaxed aesthetic. When it comes to dressing for summer-to-fall weather, nothing beats a neat combination that will keep you comfy and looking your best. As you see here, even in your 60s your dressing options are in no way limited.
