This casual combo of a white and navy horizontal striped crew-neck sweater and navy sweatpants is very easy to put together without a second thought, helping you look seriously stylish and ready for anything without spending a ton of time searching through your wardrobe. To add a little zing to your ensemble, add a pair of white low top sneakers to the mix. An ideal ensemble to make you a well-dressed gentleman over 50, rather than just a gentleman over 50.
