As you can see here, it doesn't take that much work for a man to look casually smart. Choose a barn jacket and a red dress shirt and be sure you'll look incredibly stylish. And if you wish to immediately dial down your outfit with one item, why not complete your look with black leather casual boots? So as you can see, this getup is a really nice idea, especially for weird transition weather, when the temps are dropping. As a gent in his 30s, you want to start dressing like an adult man. If that's the case, ensembles like this are a life saver.
