Combining a yellow crew-neck sweater with white dress pants is a great option for a dapper and sophisticated look. Our favorite of a multitude of ways to round off this outfit is with loafers. In winter, when warmth is above all, it can be easy to settle for a less-than-stylish look. This look, however, is a practical illustration that you can actually stay warm and remain stylish in winter. Looks like this have a sophisticated air that befit mature men very well.
