This off-duty combination of a beige crew-neck sweater and a white crew-neck t-shirt is a fail-safe option when you need to look nice in a flash. For something more on the elegant side to complete this outfit, complement your ensemble with a pair of tan suede casual boots. It's is an exciting option if you're hunting for a killer summer-to-fall outfit. All in all, a great example of off-duty fashion for mature men.
