Reach for a navy denim jacket and grey dress pants if you're aiming for a sleek, sharp getup. Take an otherwise mostly dressed-up outfit in a less formal direction by wearing white low top sneakers. So as you can see, it's super easy to look on-trend and stay snug when chillier weather comes, thanks to this look. So if you're looking for a nice and age-appropriate ensemble for a young man, this just might be it.
