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.
