Dude.. Sometimes (a lot [blame laziness]) I take a shower and then put my clothes back on. The only thing unhygienic about that in my opinion would possibly be underwear. Which I still think is probably good for at least 2 days. But if that's an issue sometimes I just go commando for a while. Either way. Unless some sweaty activity was done prior, or possibly mud wrestling or something. I don't think clothes are really all that gross after just one day
