Out of 1,000 people responding to an informal poll conducted by the underwear maker, 45% admitted they had worn the same pair of undies for two or more days, with 13% saying they had worn the same pair for a week or more, Tommy John said.

“Conventional wisdom — and basic common sense — tells us that we should change our underwear every day, or at least wash them after every wear,” Tommy John said in its statement announcing the results. “But how many people actually follow this golden rule? After surveying 1,000 Americans, we found that this basic standard of underwear hygiene is definitely not universal.”

In a finding that did not surprise the company, Tommy John said men were 2.5 times as likely as women to wear unwashed underwear for a week or more. That’s 20% of men versus 8% of women.
