Summer wear, of course, or continuous wear in warmer climates. Somebody a few years ago brought up this question about shorts and blazers at ask andys. Most thought it was a terrible idea because they couldn't visualize it with the right combination and attitude. Looking at the picture above it is shown that it can be done pleasingly. Some businesses this would work fine. Some businesses are staunchly stagnant. But even in some banks some males could do this and look correct as attitudes have certainly changed considerably in the last 50 years. There are always plenty of males that need to wear long pants, but those who don't need to this is a nice break.
