This is mostly for the guys, but you women can join in too if you like. Pretty much this is the question: let’s say you were too lazy to do your laundry and ran out of clean underwear. Would you rewear an old pair or quickly do a load of washing?
This falls under several categories, and I’ll just give my answers:
Boxers: Yeah
Boxer-briefs: Washing
Briefs: Washing
Thongs: I’d never wear these clean! 
I’d rather go without than rewearing undies. Of course I would have to go a month or so without washing clothes to run out.
My boyfriend, however, doesn’t think twice about rewearing underwear. Something that he started doing when he went to boot camp. He said something along the lines of they didn’t have enough to last from laundry to laundry. Of course before the navy he didn’t wear any.
Undies? What undies???
We don’ need no stinkin’ undies!!!
I rewear them for at least one extra day even when I do have a clean pair on hand.
There’s no sense in doing extra laundry when I don’t need to.
I don’t have a problem with it. If I’m out of clean undies, I’d wear those from yesterday. But if I have to dig into the laundry basket to get at it, I’d rather go without.
I hate underpants, but “they” say I have to wear them, and if I am going to wear them, they MUST be clean. If I can’t smell fabric softener, then they aren’t clean. Same applies to my husband: none of this college boy “turn-'em-inside-out-and-spray-'em-with-deodorant” stuff (mostly because I say so, or else no nookie!).
Fortunately, I usually do the laundry, and when I start to get down to only about 5 or so clean pairs of panties, I will toss a load in the machine. It is not uncommon for there to be a load of wash in our house that is nothing but underwear.
Also, when I travel I always keep at least two spare pairs in a Ziploc bag in my carry-on, in case of emergencies. In the event of sheer desperation, I will wash my underwear in the hotel sink. Under NO circumstances will I wear underwear for more than 36 hours in a row without changing, and once they hit the laundry pile, they stay!!
In case of emergency, or if I wake up late for class (okay, so that’s pretty much a daily occurrence)
Ew! Ew, ew, ew, ew, ew!!!
I wouldn’t dream of wearing underwear more than one day.
If I take a shower at night (rare because I shower in the morning) and put on clean underwear, I’ll still change them in the morning.
I wouldn’t rewear them, but I’ve been known to wash them by hand in the sink.
Once the panties are removed, they do not get put back on again. Even if I have to go commando.
If I shower the night before, and put on a pair before bed, I have no problem wearing them the next day. In a pinch, if I need underwear and have none clean, I just put on a pair of gym shorts or something. Otherwise, I freeball.
In a pinch, yeah I rewear underwear. If camping or some similar activity I might go 48 hrs with out changing. Any longer than that and I can’t stand that “not so fresh feeling”.
Slight Hijack… Once while traveling, I got stranded in Chicago’s O’hare airport. The ticket agent was nice enough to get me a complimentary hotel room. The only thing, my luggage was sent on to the next destination. I stayed at the O’hare Hilton, (like on the 8th floor). Having had worn the current pair of tighty whities for nearly 60 hrs at this point I decided to wash them out in the hotel sink. My departing flight left the following morning at 6am so I planned to hang the wet underware in front of the heater vent to dry in time. I come out of the bathroom with wet underware in hand to find the air vents were in the ceiling!!! No way to hang them up there, believe me I tried everything I could think of!!
Sooooo … I hung them on the lamp shade instead…big mistake. I wake up 45 minutes later and …MY UNDIES ARE SMOKIN!!!
PANIC ENSUES…
Thankfully the smoke detectors hadnt gone off!! All I could imagine was having to run out of the room naked if they and the rest of the room had actually caught on fire (sleepin naked cuz no luggage you see…)
Moral of the story is:
PART - 1
Always remember to carry extra set of underware and bathing sundries in briefcase carry-on
PART - 2
Always remember to remove underware from the briefcase BEFORE going to a client presentation!
No. I would never wear underwear more than once. I would rather not wear underwear.
I only own boxers, but yeah, I’m somewhat embarrassed to say I’ve done it on occasion. I gotta make an effort not to put it off this year. 
Have I got it right that people put on fresh undies to got to bed? Why? This is an honest enquiry - I know the woman down the road from me always wore underwear under her nightie, and made her daughter do the same. I never understood why, but couldn’t quite bring myself to ask why. I never wear anything, but I can just about understand people wearing nighties or jammies, but underwear? So restricting…
Most of my clothes I don’t have a problem wearing for mutiple days, but underwear I’m not so sure of. If I have nothing else I’ll rewear them(or did something stupid and forgot to pack a pair), but most of the time I’ll change my undies on a daily basis.
I am ashamed to admit that a couple times in college I turned my boxers inside out. I would rather go commando than do that with my tighties, though.
Nowadays if I run out and I can’t do laundry, I wash a pair or two in the sink.
On the rare occasions that I actually wear underwear, I try to wear clean pairs.
I’ve done it on occasion, but mostly I’ll go without. (I have a bad habit of losing underwear; I lose it the way other people lose socks. I don’t know where it goes. So I rarely have enough to last me even a week.)
Never. In a situation where I haven’t got any more clean ones, I either a) wash them in the sink the night before and hope they’re dry by the morning, or b) do without.
