Wear a navy turtleneck with charcoal wool dress pants if you're going for a neat, classic look. And if you wish to easily dial down your look with one piece, introduce dark brown suede desert boots to this outfit. We highly recommend this one if you're on a mission for a comfy look that's as stylish as it is comfortable. As a 30-something man, you want to start dressing more like a mature gentleman. In this case, inspo like this comes in handy.
