For a look that's classy and totally GQ-worthy, wear a navy wool blazer with charcoal dress pants. A good pair of brown leather brogues is an easy way to give a dash of stylish casualness to this getup. As the weather warms up, it's time to get rid of those heavy winter clothes and choose something lighter, like this getup here. An ensemble like this can make any 40-something gentleman look better than any of his peers.
