A white shirt looks so nice when married with blue jeans in an off-duty outfit. For something more on the dressier end to round off this outfit, complete this ensemble with a pair of white and green canvas low top sneakers. This outfit isn't a hard one to nail and it's season-appropriate, which is most important when it's extremely hot outside. Ideal if you're on a mission for some incredibly inspiring laid-back style for 50-year-old guys.
