This modern casual combination of a black crew-neck t-shirt and black cargo pants is super versatile and apt for whatever the day throws at you. Take a more laid-back approach with shoes and complement your outfit with a pair of black athletic shoes. Needless to say, it's easier to work through a boiling hot summertime day in a fresh outfit such as this one. When it comes to casual fashion for men over 50, this combo is a good look on almost any man.
