Underwear brand Tommy John surveyed 2,000 men and women to see how long they wear and keep their underwear.
Forty-five percent admitted to having worn the same pair of underwear for two or more days, while 13 percent claimed to have worn the same pair for a week or more.
If you're wondering who are the repeat offenders? Tommy John's study shows men are 2.5 times as likely as women to wear their underwear for a week or more.
The study also shows 46 percent of Americans have owned the same underwear for a year or longer, and 38 percent claimed they have no idea how long they've had their underwear.
