This casual combination of a navy zip sweater and jeans is super easy to throw together without a second thought, helping you look awesome and prepared for anything without spending too much time rummaging through your wardrobe. Black suede oxford shoes will immediately polish off even the laziest of getups. As you might be rightly thinking, this is a neat idea when warmer days are here. All in all, a perfect example of smart casual fashion for middle-aged gents.
