lol. I had a psych professor who wore a full zip-up mechanic's jumpsuit every day. He was a behavioral psychologist and said he didn't want people to react differently to him based on what he was wearing each day.
lol. Well, he failed at that. If he'd picked something bland, sure. But instead he decided to be the teacher whose clothes stand out most so probably got the most behavioral reactions out of it.
I know! White shirt and black pants, and no one would have even noticed his clothes. Maybe it was part of a research project and we were all subjects. Who knows.
I had a teacher in college that wore the same 2 outfits maybe all semester or most of it at least. I think she had a Tuesday outfit and a Thursday outfit.
I wouldn't notice normally just twice unless it was really unusual.
