Looks like pizza parties and tchotchkes aren’t the only way for a company to note sales milestones and records.

In celebration of record-breaking sales, the Audrey Underwear company in Taizhong, Taiwan recently encouraged its female employees to show up to work in their undergarments for a day.

Huang Bihui, the PR manager of the company, explained that eight new lines of camisoles were introduced and sold more than 20,000 units in under two months. The company figured there was no better way to celebrate than to parade around in the same business-boosting ensembles.

Sound like a legal disaster waiting to happen? Not this time. The company’s employment lawyers cleared the whole thing before making the announcement, and because participating in the day’s “activities” was voluntary, nothing was illegal about it.

More than 90% of the company’s female workers showed up in spirit of the day.

Odds are good that productivity came to a day-long standstill.
