Oh, this is fascinating -- thank you so much, those who replied. I see a pattern with many of us remembering what teachers wore (for good or ill!) and I have several similar stories of my own.
In answer to your question, Gaylene, I don't think people much notice what I'm wearing. But of course, that's silly, because they do notice -- I get lots of compliments on my outfits. Including from my students. I don't think last year's group had contests related to my outfits but they certainly had favourites and would say things like, "Oh, yay, she's wearing the red jacket and mask today!"
Dee and Kkards, I can definitely understand why you wouldn't want to wear the exact same outfit to work on every Tuesday (for example). I would not do that, either. In fact, I distinctly remember standing in front of the closet last year and trying to reconstruct the previous week's outfits so I wouldn't..But I would repeat the same outfit randomly and did wear the same thing with the same group a bunch of times.
Ditto to what Janet said, also. I have been guilty of the same thing -- wearing the exact same outfit to holiday events a few years in a row, and it speaks to the importance of beefing up or carefully editing the dress up capsule, especially if some items aren't fitting right any more...
I had those teachers, too, who wore the same thing all the time. I wondered about it -- I mean, a teacher's salary is not grand but it does allow for a couple of shirts and trousers, surely. Like Rachylou, I wondered about hygiene. But also like she says, kids can be so mean! For all we know, this teacher had identical shirts and pants for seven days.
Still in the realm of teaching, I had a colleague (male) who was one of the most stylish people I've ever known -- he only wore a uniform. He has white hair (though his skin was still young -- he was probably in his late 40s or early 50s; I was in my early 30s). Anyway -- he wore white shirts (different styles but all white and always white), black trousers (again, different styles, but black), and black jackets. He looked impeccable and amazing every day. And often wore the exact same outfit -- but this was clearly a signature style.
