For a laid-back ensemble, make a white vertical striped long sleeve shirt and brown chinos your outfit choice — these two pieces go nicely together. To give your overall look a classier vibe, why not complement your look with dark brown leather brogues? So as you can see, it's very easy to look on-trend and stay comfy come fall, all thanks to combinations like this one. As a gentleman in his thirties, you want to start dressing like an adult man. That's when combinations like this become a great source of inspiration.
