Want to infuse your menswear arsenal with some off-duty cool? Reach for an olive shirt jacket and white jeans. For something more on the daring side to complete this look, add black leather low top sneakers to the mix. So if you're on the lookout for an outfit that's on-trend but also totally spring-ready, this is it. Think it's hard for guys in their 40s to perfect modern off-duty dressing? This combo is definitive proof of otherwise.
