This combination of a light blue denim jacket and a grey crew-neck t-shirt is on the casual side but guarantees that you look sharp and truly stylish. You can get a little creative on the shoe front and complement this outfit with grey canvas desert boots. So as you can see, this ensemble is a really nice option, especially for in-between weather, when the mercury is falling. This pairing proves that as a gent in his sixties, you still have a wide range of style options.
