One of the most popular ways for a man to style a black denim jacket is to combine it with beige chinos for an off-duty outfit. Infuse a dose of stylish nonchalance into your ensemble by finishing with beige canvas high top sneakers. This ensemble isn't a hard one to score and it's season-appropriate, which is more important when it's extremely hot outside. Think mature gents can't pull off edgy casual dressing? This pairing is irrefutable proof of otherwise.
