I hate to echo what has been said, but those who are most in need of this info are the least likely to read it! LOL
As for me, the only things I will wear more than once between washings are outer clothes, such as uniform shirts which go over a tee-shirt; or sweatshirts worn over a tee shirt. This time of year, in the fall, sweat shirts often end up worn half a day and then tossed in the car as the day warms up. I feel comfortable wearing them several days.
I think this is a highly varying and personal choice sort of thing. If you have work and/or hobbies which get your clothes dirty (such as vintage appliance repair!) that makes a big difference. In my case, even though my clothes may still smell nice; if they have grime and dirt on them they get washed daily.
All I wear are low-cost clothes and work clothes. I have nothing dressy. It doesn't cost me much to have a full set of clothes for each day for 8 or 10 days. For that reason, I really don't have any reason not to put on a fresh set of clothes daily. I would understand if you had a limited number of outfits or if your work required a certain dress and you had only so many sets of work clothes. But for me personally I like to have fresh clothes daily.
