So, in fairness to the wife- there are many people who might see a woman’s panties multiple tiles in the same week, even if she is faithful.
Female friends (or friends of other genders), coworkers in the same bathroom may occasionally see them as well depending on how far down she pulls them to go. People using the same locker/shower facilities at work/gym etc. if she has something going on with the doctor they might see them multiple times in a week. If she wears pants/skirts then there are many people who might see the band during her daily activities wether that’s getting out of a car/bus/train/desk seat, going up and down stairs, or other times where her bottoms may slip a bit or her top may ride a bit. And of course, many yoga pants/leggings can show panty color through the material under the right conditions- these pants are very popular and also generally do not have provisions for belts either making routine adjustment more likely.
Would be weird if she saw all these people everyday. Would be weirder if folks remember what panties she was wearing from last time they were at the gym together.
I’m not so sure. Granted- some people are just oblivious. They aren’t present in any given moment. Some people can get a ride home from someone 6,10 times or more and not know what car they drive, or even what color it is. Some people won’t notice the eye color of a person in they spoke to, don’t notice when a house on their block has planted new flowers, put up a new fence, or even been painted. And that “some” tends to be a great big number or people. Maybe even a majority.
But- if you wear the same pants for 5 days in a row- wouldn’t people notice? Does that mean they are staring at your legs for some odd reason? If you pee yourself or leave a poo stain in your pants- people will notice too- does that mean they were staring at your crotch or butt? Maybe. Maybe not.
When I go to the gym, there are people I see all the time. I don’t know them, and have never spoken to many. But we see each other every day just about. I know what work puts they do, how they warm up, what time they usually come and go. It’s not something I’m looking for- but seeing them all the time, you notice, unless your head is in the clouds.
Same when you commute on public transit. You eventually will start to see people you recognize and notice patterns- if you’re situationally aware at all anyway. I’ve also done manual labor- technical jobs with teams where we have to contort and twist under and inside machinery and tight spaces. Your underwear will show. Your buddies will. And you can’t really not see it. You’re spotting them for safety or watching for signals to pass them tools or equipment, or take cables or etc. so you can’t really look away even if you aren’t jammed in somewhere butt to face- you’re seeing legs and butt and occasionally a hand shoot out.
So I still hold my original stance that there are plenty of scenarios where a person may regularly glimpse your underpants- and just like pants, or a shirt, or the same lunch everyday, the same coffee order- as humans, if we are paying any attention at all we are wired to notice patterns and we will notice if someone wears the same thing over and over- especially if it is done consecutively.
But I do concede the caveat that many people just are oblivious or so preoccupied inside their own heads that they might not wen notice of their own live in romantic partner wore the same thing days in a row.
