The combination of a dark brown crew-neck sweater and olive chinos makes this a solid relaxed ensemble. You could perhaps get a bit experimental on the shoe front and dial down your look by finishing with white and green leather low top sneakers. Ideal if you're on the lookout for some incredibly inspiring style for middle-aged guys.
Consider pairing a dark brown crew-neck sweater with olive chinos to confidently deal with whatever this day throws at you. A pair of burgundy leather derby shoes will give a dressier twist to this ensemble. So if you're on the lookout for outfit inspiration for dressing after fifty, this combo is definitely worth saving for later.
