One of the best ways for a man to style a long sleeve t-shirt is to combine it with khaki cargo pants in a casual combination. If you want to immediately dial down your ensemble with shoes, why not complete this getup with silver athletic shoes? If it's one of those dreary autumn days, what better to cheer it up than a sharp look like this one? Think you can't pull off modern casual dressing as you step into your 50s? This combination is a vivid demonstration of otherwise.
