To achieve a casual outfit with a fashionable spin, rock a light blue vertical striped shirt jacket with charcoal chinos. Add an easy-going touch to by slipping into a pair of white athletic shoes. Keep this combo in your front hall wardrobe come warmer days, and rest assured, you'll save a ton of time getting dressed on more than one morning. All in all, an ideal demonstration of off-duty style for 40-something guys.
