Such items as a black overcoat and a black crew-neck t-shirt are an easy way to inject some masculine elegance into your off-duty lineup. Throw in white low top sneakers to bring an element of stylish effortlessness to this look. This getup is also perfect if you're on a mission for summertime wear to make a boring day more bearable. No doubt, a smart choice when it comes to outfit ideas for middle-aged guys.
