Pair a shirt jacket with an olive short sleeve shirt to put together an interesting and put together outfit. And if you need to instantly dress down this look with a pair of shoes, add a pair of white and black athletic shoes to the mix. As you can see, it's super easy to look dapper and stay comfortable when colder weather comes, all thanks to combos like this. Think middle-aged gentlemen can't pull off cool off-duty dressing? This combo is a powerful demonstration of otherwise.
