This semi-casual combo of a black sweater vest and teal corduroy chinos is very easy to put together without a second thought, helping you look on-trend and prepared for anything without spending a ton of time rummaging through your wardrobe. For an on-trend on and off-duty mix, add a pair of black leather desert boots to the mix. There's no nicer way to cheer up a dull fall afternoon than an on-trend getup like this one.
