This smart combination of a beige cable sweater and a white dress shirt is very easy to put together in next to no time, helping you look awesome and ready for anything without spending too much time digging through your wardrobe. If you need to easily dial down this ensemble with shoes, complete this outfit with charcoal suede desert boots. As you can see, this outfit is a really good pick, especially for weird transition weather, when the temperatures are dropping. Certainly a wonderful choice when it comes to outfit ideas for 40-year-old guys.
