You've been really busy with, you know, life and haven't had time to get to the ever-growing mountain of laundry that's piling up in your closet. Now you're down to your last pair of clean underwear. You've found yourself wondering, "how bad is it, really, to re-wear underwear for another day?" Although, generally speaking, it's probably not as bad as you'd think, there are a few surprising icky things that happen when you wear your underwear two days in a row.
Now, let's make something clear: if you don't need to don the same pair for an extra day, you may not want to do it all that often. According to the Girl Smarts website, it's always best to wash your underwear after each wear. That being said, you can get away with a double wear. In an interview with Greatist, associate clinical professor of dermatology Dr. J. Scott Kasteler said that as long as the underwear is visibly clean there shouldn't be a problem wearing them again. If they appear dirty (or sweaty) in any way, however, you should definitely throw them in the wash or you might find yourself dealing with one of these five issues that arise when you do more than a double wear.
