One of the most popular ways for a man to style a long sleeve shirt is to combine it with light blue jeans in a casual combo. To give your look a more laid-back finish, why not complete this ensemble with a pair of red and white athletic shoes? So as you can see, it's extremely easy to look sharp and stay comfy when colder weather hits, all thanks to outfits like this one. Perfect if you're scouting for some amazingly inspiring style for over-40 guys.
