For laid-back refinement with a manly spin, you can easily rock a white crew-neck t-shirt and a tan trenchcoat. Shake up your outfit with a more casual kind of shoes, such as this pair of blue canvas low top sneakers. This ensemble is a pretty good option, especially for fall, when the mercury is getting lower. You can take inspiration from getups like this if you're in your 30s and you want to take a more mature approach to your style.
