A grey duffle cardigan and cargo pants married together are a match made in heaven for those who appreciate cool and relaxed ensembles. And if you wish to easily dress down your outfit with a pair of shoes, why not complete your look with black and blue athletic shoes? It's a good pick if you're picking out a well-coordinated ensemble for weird fall weather. Just because you've reached your 40s, doesn't mean you shouldn't look stylish, and this pairing demonstrates just that.
