This ensemble with a cardigan and navy chinos isn't super hard to score and easy to adapt according to circumstances. If you want to break out of the mold a little, add dark brown suede derby shoes to your look. And if we're talking style for mature guys, this outfit looks good on almost any gentleman.
A cardigan and navy chinos are the kind of a tested casual getup that you so desperately need when you have no time. Why not take a more casual approach with footwear and complement this outfit with a pair of white leather low top sneakers? This combination is a big inspo to anyone who wasn't sure about donning casual outfits as a 40-year-old.
