Marrying a short sleeve shirt with a charcoal crew-neck t-shirt is an awesome idea for a casually stylish look. Complement this outfit with a pair of grey canvas low top sneakers et voila, this look is complete. It's a viable idea if you're putting together a cool ensemble for summer-to-fall weather. This ensemble should prompt anyone who wasn't sure about donning casual outfits as a guy in his 50s.
