Sensible office wear

In the old days, businessmen would never be seen in the office without a suit and tie. Short-sleeve shirts and T-shirts were simply unheard of in cities' financial districts.

But the matter of what to wear to the office is no longer so simple. Work attire can actually make a big difference to energy saving in the scorching hot summer.

Nobody wants to sit at their desks in a hot office, sweating under heavy suit jacket. So if the rule is all employees wear suits and ties, air conditioners must also be lowered to maintain a reasonable temperature. After all, a comfortable temperature results in greater productivity.
