If you're looking for a casual and at the same time sharp ensemble, choose a cardigan and a white and red crew-neck t-shirt. Brown suede high top sneakers will bring a fun touch to an otherwise mostly classic outfit. So as you can see here, it's a killer, not to mention spring-appropriate, outfit to have in your seasonal rotation. A no-brainer getup proper for gentlemen in their 60s who like casual dressing.
