If you don't like being too serious with your combos, consider teaming a white and green long sleeve shirt with navy jeans. If you wish to instantly bump up your outfit with shoes, why not choose a pair of loafers? As the weather warms up, it's time to get rid of those heavy winter gear and choose a look that's lighter, like this one here. A good pairing to make you a sharp-dressed gentleman in his 40s, rather than just a gentleman in his 40s.
