One of the coolest ways for a man to style a grey crew-neck sweater is to combine it with navy jeans in a casual combination. You can get a little creative in the shoe department and introduce black canvas high top sneakers to the equation. A nice, less conservative getup for a guy in his forties.
Marrying a grey crew-neck sweater and blue jeans will prove your skills in men's fashion even on lazy days. Play down the dressiness of this look by slipping into a pair of black canvas high top sneakers. If you're often not sure how to dress age-appropriately, this combo is a real life saver.
