A denim jacket and a yellow crew-neck t-shirt are a pairing that every modern guy should have in his casual styling routine. For times when this outfit is too much, dial it down by slipping into a pair of brown leather work boots. It's a great idea when it comes to putting together a well-coordinated look for transeasonal weather. Just because you're over 60, doesn't mean you should give up on fashion, and this getup proves exactly that.
