Tokyoites are bracing themselves for a scorching, sweat-filled summer, cocktail plus size dresses indoors and out. As the word setsuden, davids bridal gowns davids bridal gowns winter cocktail dresses 21st birthday sashes 21st birthday sashes or save electricity, becomes a buzzword, prom ball dress prom ball dress government offices and many firms have pledged to keep the office thermostat at a steamy 28 degrees Celsius—82 degrees Fahrenheit—due to a government decree to cut electricity usage by 15% this summer thanks to its now-crippled nuclear-power plants.

The launch of the campaign, which includes a fashion show coordinated by the environment ministry and Uniqlo department store, encourages government employees to abandon their dark suits and for the light-weight shirts and respectable-looking jeans, chinos and polo shirts to prevent a human meltdown this summer.

But for many government officials, who collectively shudder at the thought of shedding the protective armor of their suits, embracing such casual wear is taking matters one step too far—even in the absence of air conditioning.

"I personally do not think it is appropriate to go out in sandals and meet people," grumbled one official from the powerful ministry of trade. "Super Cool Biz would be difficult to implement at [the trade ministry], because we receive lots of guests from outside the ministry, including many foreigners."

Another bureaucrat tulle dresses for prom , who declined to be named, said, "It's like Silicon Valley versus Wall Street. [The environment ministry] is like Silicon Valley and other ministries are more conservative."

A younger transport ministry official agreed: "I can imagine keeping a suit at my desk to change into when meeting people, but I can't imagine meeting guests in a T-shirt or a polo shirt."

Retailers, however, have enthusiastically jumped on the Super Cool Biz bandwagon. "This is a big chance for us plus size bridesmaid dresses under 100 dollars plus size bridesmaid dresses under 100 dollars," said Naoki Ootoma, chief operating officer at Uniqlo, the country's leading clothing retailer, adding that it has estimated that an average consumer will spend around ¥17,000 ($210) on a new Super Cool Biz wardrobe. To make decision-making easier for the dress dress -sense-challenged, Uniqlo unveiled eight casual looks appropriate for Super Cool Biz style at an event Tuesday, including one that featured white shorts paired with a plaid button-down and a blazer.

Noriyuki Nishikawa, an employee at Japanese confectioner Morinaga & Co., modeled a Uniqlo polo shirt at the event. "We're not allowed to wear polo shirts at Morinaga, but I'm going to go back to the office today with this on and see how people react," he said.

In the private sector, most blue-chip companies such as Sony Corp. haven't embraced the Hawaiian-shirt aesthetic, though they do encourage employees to lose their neckties and jackets this summer. One exception is Ito-En Ltd., the beverage company, which says its employees—male and female—can wear white polo shirts starting June 1.

Curiously, the environment ministry has steered clear of issuing guidelines for female employees on what to wear during Super Cool Biz. "It was more difficult to come up with guidelines for women," said one ministry official, "so we are letting them decide."

Still, many are lauding the efforts most Japanese are making to conserve power. "I don't want to play down the initiative taken by a fellow government agency. This is a time of emergency. We need a completely new way of thinking," said the trade ministry official. "I don't think we can ride out the current [energy] crisis by continuing the same tired approach."
