A waistcoat looks especially refined when matched with a white and black dress shirt in a modern man's combination. And if you need to immediately dress down this outfit with one item, why not introduce a pair of brown leather casual boots to this getup? With an ensemble like this in your winter arsenal, you're guaranteed to stay toasty and look stylish despite the subzero temperatures. This combination proves that dressing cool as an over-60 gentleman is easier than one might think.
