I myself don't nessisarily re-wear the same clothes for days in a row, but a lot of times I end up re-wearing stuff. Like I might wear a pair of pants one day, then wear a different pair the next day(because maybe the other ones create a color combination with the shirt I want to wear that I don't like) then switch off between those two pairs all week...and maybe re-wear the same shirt if it doesn't get all smelly from armpits sweating.
a lot of times when I sleep I put on pajama pants and just leave on the shirt I wore that day, and sometimes wear it into the next day....I may change if it I end up having to go somewhere and want something that looks cleaner.
As for hoodies and sweaters I have so many of those I just tend to grab whichever one I see first, if it doesn't contrast too bad with whatever pants I have. For instance I don't like to wear my green and white striped drug rug/hippie sweater with my reddish pants that have a snake print design on them. So in that case I'd probably grab a plain colored sweater or hoodie.
