A red and black plaid long sleeve shirt and a white crew-neck t-shirt will bring extra style to your daily off-duty arsenal. You could perhaps get a bit experimental in the footwear department and complement this look with a pair of tan canvas high top sneakers. This look is also great if you're in search of summer wear to make a boring day more tolerable. This outfit is a huge inspiration to anyone who wasn't sure about sporting casual outfits as a 40-something man.
