answer:I pretty much stopped doing that my second year of college, 40 years ago. Even though I shower once or twice a day, and use deodorant, I don’t wear shirts, underwear, or socks more than once without washing. The exception is pants. But my pants don’t accumulate odor before I wash them again. I’ll wear them three or four times before washing them again. Unless I have been on an airplane. Whatever pants I wear on an airplane get washed right away.
