Listen up, lazy people who don't mind smelling just a LITTLE bad. (After reading what the experts say, I include myself in the category.)
Here's how many times you can wear different types of clothing without washing them, according to experts. They're basing this on the smell . . . but more than that, on the bacteria that can form and what it can do to you.
Pajamas: Once a week if you shower before bed. Daily if you don't shower first.
Coats and jackets: Once a month.
Jeans: Once a month.
Underwear: Once a month if you sell it to perverts on the Internet. For the rest of us . . . yeah, don't re-wear your underwear.
Socks: After wearing them once.
Workout clothes: After wearing them once.
Shirts: After wearing them once if they had direct skin contact. You can go a little longer if you're wearing them over another shirt.
