The only clothes I do this with are my jeans for work and that's it. I used to have a bad habit of wearing the same socks over and over again for days but I couldn't do that now. Looking back, I'm even surprised I did this and wasn't bothered by it. I could never wear the same underwear over and over again that's for sure. I feel that pants are different, as long as I don't spill anything on them they're fine.
