This combination of a navy crew-neck sweater and jeans combines comfort and efficiency and helps you keep it simple yet trendy. If not sure as to what to wear when it comes to shoes, introduce a pair of white and navy low top sneakers to this getup. As the weather starts to improve, it's time to get rid of those heavy winter clothes and opt for something lighter, like this getup here. This pairing is a great inspiration to anyone who had doubts about donning casual outfits as a 50-year-old gent.
