Why not pair a denim jacket with a crew-neck t-shirt? As well as totally functional, these pieces look cool when worn together. Rounding off with light blue athletic shoes is a surefire way to inject an easy-going touch into your outfit. So if you're on the hunt for an ensemble that's sharp but also entirely spring-ready, this one is great. Casual looks for stylish 60-something guys aren't actually that hard, as you can see.
