Pair a dark brown wool blazer with charcoal wool dress pants for sophisticated style with a modern spin. If you wish to effortlessly dial down this outfit with a pair of shoes, introduce a pair of tobacco leather casual boots to the mix. This combination is a good choice when it comes to piecing together a knockout outfit for transitional weather. As a 30-something man, you want to start dressing with more refinement. That's when inspiration like this is very useful.
