I've been retired for 4 years after the job of 37 years was taken away. I often wear jeans 4 days to even two weeks, depending on the circumstances. Winter season, no sweating, no yard work, no food spills, sitting at the computer or on the sofa watching TV ... they don't get "dirty." Or cargo shorts in the summer several days under the same circumstances. I wear the worn jeans with frayed cuffs and faded knees for daily at-home, no one sees me, no one cares. Switch to better pairs for store runs, appointments and such, they don't get dirty in those brief excursions. I have separate ragged-out shirts and jeans or shorts for yard work.
