If you prefer laid-back style, why not take this combination of a black crew-neck t-shirt and grey wool chinos for a walk? Tap into some David Gandy dapperness and smarten up your getup with brown suede derby shoes. As the weather warms up, it's time to get rid of those bulky winter layers and choose a look that's lighter, like this one here. This combination demonstrates that as a 30-year-old man, you have a wide range of style options.
