We're loving the way this pairing of a dark brown suit and a white polo neck sweater immediately makes a man look refined and sharp. For something more on the casual end to complete your look, introduce black leather loafers to this look. If you're on the lookout for a neat winter-to-spring outfit, you found it. So if you need outfit inspiration for dressing as you go into your 40s, this combination is definitely worth saving for later.
