This combination of an overcoat and a white and navy crew-neck t-shirt is hard proof that a straightforward ensemble doesn't have to be boring. For something more on the classier end to finish off your look, introduce a pair of black leather derby shoes to the mix. This one is a wonderful idea when it comes to piecing together a well-coordinated ensemble for summer-to-fall weather. Think it's hard for middle-aged men to perfect cool off-duty looks? This combo is indisputable proof of otherwise.
