This pairing of a navy vertical striped shirt jacket and navy chinos is definitive proof that a simple off-duty getup can still look really interesting. Go off the beaten path and jazz up your getup by rounding off with white canvas low top sneakers. So so as you can see, it's a killer, not to mention spring-ready, combo to have in your transitional rotation. And if we're talking casual clothing for 30-something Millennial men, this combo looks cool on most.
