You'll be amazed at how easy it is for any gentleman to pull together this off-duty getup. Just a crew-neck sweater and a black crew-neck t-shirt. For something more on the dressier end to complete your outfit, throw in a pair of black leather derby shoes. Seeing as the weather is getting colder every day, this outfit appears a wonderful option for the season. If you're not sure how to dress age-appropriately without giving up on fashion at 60, this pairing is a practical example.
