This combination of a black crew-neck sweater and black jeans is a nice look for when it's time to clock off. The whole ensemble comes together really well if you introduce a pair of white leather low top sneakers to the mix. When leaves turn yellow and red and fall starts to take over, you'll love this combination as your go-to for transeasonal weather. This combination should inspire anyone who had doubts about wearing casual outfits as an over-40 man.
