You're looking at the solid proof that a tan double breasted blazer and a navy cardigan are awesome when paired together in a refined outfit for a modern gentleman. For extra fashion points, complete this look with a pair of dark brown leather loafers. So as you can see, this getup is a really smart option, especially for transeasonal weather, when the temperature is dropping. This is an outfit you, as a gent in his 40s, can always count on.
