Pairing a white short sleeve shirt with light blue jeans is a smart pick for a laid-back and cool getup. When this outfit appears all-too-fancy, tone it down with a pair of white and navy athletic shoes. Springtime is a wonderful time of year and it calls for standout looks just like this one. This ensemble is a big inspiration to anyone who had doubts about donning casual outfits as a gentleman in his 40s.
