I grew up in Indiana, in the interior of the US. I'm female, if that helps. It was never acceptable for me to wear the same thing for days in a row. This is so pervasive that I used to have a system to make sure I avoided that while not having to launder things if they weren't dirty. The first person I met that did that was an exchange student from Germany - we were both 17 at the time. I've since moved to Norway and really don't know anymore if folks notice: I always just wear black and usually buy multiples of the same item. Even if I wear something different, it looks the same. Plus, half of my social group is other immigrants and might not represent society really well.

I've heard similar things from women who worked in majority-women offices in e.g. HR. They were expected to steadily rotate, even wearing the same vest over other stuff two days in a row would result in questions "where they had slept last night" from their co-workers.

Rotate then. You don't have to wash it every time.
