Consider wearing a light blue denim shirt and blue jeans to assemble an interesting and current off-duty outfit. If in doubt about what to wear on the footwear front, complete your getup with a pair of navy print canvas slip-on sneakers. As the weather begins to warm up again, it's time to shed those bulky winter gear and opt for an ensemble that's lighter, like this one here. Now that's how you keep it casual in the fashion department as an older man.
