For relaxed dressing with a modern spin, make a red and black plaid long sleeve shirt and a white crew-neck t-shirt your outfit choice. For an on-trend hi/low mix, complement your outfit with black athletic shoes. As you can see here, this combo is a really savvy idea, especially for transitional weather, when the mercury is dropping. Perfect to tell people that even as a younger gent you're confident enough to hold your own in the sartorial department.
