So here’s the scenario: you’ve just worked out and showered, and realize you forgot to pack clean underwear*. Do you wear the underwear your wore while working out (60 minutes, moderate intensity), or spend the afternoon freeballing in you cotton dockers?
It depends on a number of things, such as if I’ll be able to putter around at home in clean dockers while I get to laundry. Or if I can go nude until my hand-washed undies dry out. But all things being equal, I’ll wear dirty undies.
Actually, this very thing happened to me last week. I washed a pair in the sink, then tried to dry them with a hair dryer. Even in the desert, that took a looooong time. But I was looking at a good 16 hours of not being able to change.
Although if I were in a skirt/dress I might turn the funky ones inside out - I have a really unfortunate story of a young woman in a dress, a spilled liquid, slippery shoes and a lack of ginch in a grocery store that would prevent me from going without in a dress I think.
One of the top leaders in my company went on a business trip and forgot to pack underwear. So he washed his in the hotel room sink every night and hung them up to dry. This story got told as an example of how resourceful people can be when they need to be. Then somebody asked, “Why didn’t he just buy some?” and everybody else said, “Oh, yeah, why didn’t he?” and the whole thing became an embarrassment.
For the record, I’d decide which to do on the basis of how clean the underwear are and what I have to be dong. As near as I can judge the OP conditions, I’d wear the underwear again.
Since I regularly don’t shower after workouts (I don’t like public showers/don’t bother looking for them/don’t even know in some cases if the gym has it), I still keep the same underwear after I change workout clothes.
In the event I’m out of clean underwears after I take a shower I either:
Wash them in the sink and dry them with whatever I have (blowdryer, on top of the AC fan, twisting them around towel, etc.).
