For a laid-back look, make a navy denim shirt and a crew-neck t-shirt your outfit choice — these items work really good together. With shoes, go for something on the casual end of the spectrum by finishing off with a pair of black leather sandals. This outfit is a safe option if you're in search of a great, summer-ready outfit. Think gentlemen in their 60s can't pull off edgy casual outfits? This pairing is a vivid demonstration of otherwise.
