Dress in a blazer and a black crew-neck t-shirt for a simple outfit that's also well-executed. For a more laid-back twist, why not add white leather low top sneakers to the equation? So if it's a hot weather day and you want to look on-trend without putting in too much work, this outfit will do the job in next to no time. Think it's hard for mature gents to nail edgy off-duty style? This pairing is irrefutable proof of otherwise.
