Don’t be surprised if your company’s new dress code allows shorts on hot summer days. Why? So they can cut back on the A/C and save money! 

The trend began in Japan, which still has rolling blackouts from the recent earthquake and tsunami. And with skyrocketing energy costs, the trend is popping up across North America, even in companies not known for casual attire, like law firms, investment companies and real estate brokers.

But even if you’re allowed to wear shorts to work, the outfits you pick can still make or break your career. Experts say your shorts should have wide hems and reach the knee like Bermuda shorts. That means no short-shorts or skin-tight ones. 

That’s just another example of how businesses are looking to save a few bucks by cutting back on air conditioning costs.
