it varies. A lot
example: I think the jeans I'm wearing now are nearing their second month? trouble is they don't need washing. They still don't smell (I'm genuinely surprised by that), aren't dirty, as in no dirt or mud or any stains on them, and beyond maybe needing to be ironed at a stretch, there is nothing wrong with them. Where as sometimes I'll put on new jeans, go play football and will have to wash them as soon as they come off. It depends greatly on who you are and what you do.
(I also think I should now wash these jeans, just because I think 2 months is ridiculous in my mind, even if I know there's nothing wrong with them)
