You'll be surprised at how very easy it is for any man to pull together this smart casual getup. Just a duffle coat paired with blue jeans. The whole look comes together if you add a pair of desert boots to the mix. In the colder months, when warmth is essential, it can be easy to settle for a less-than-stylish outfit in the name of functionality. However, this outfit is a clear example that you can actually stay toasty and remain equally stylish during the colder months. This combination is ideal for 60-year-old guys.
