Go for a straightforward but cool and relaxed outfit in a blue chambray long sleeve shirt and a white crew-neck t-shirt. If you want to easily tone down your getup with one item, add brown athletic shoes to the equation. And if you're on the hunt for a cool look that will take you from winter to spring, this one is great. Laid-back looks for gents over 30 aren't actually that hard, as you can see.
