Semi-used clothing storage

Where do you store clothes that you used during the day but you still want to use tomorrow? Like those jeans you really like, or that shirt you used only for a few hours. I've been using the carpet, and sometimes the chair, but I wondered if anyone had found a neater or more standard place to store multi-day clothing. It would be especially useful for when you change your mind your next day and decide to put on clean clothes, but then you might accumulate two sets of lightly used clothes that you might want to use again. You don't want to fold them and put them back with the clean piles, and it's becoming a little pile on its own. What to do? What to do...
