It depends on the time of year as to whether I can wear some clothes more than once. For example in the winter, I will wear clothes over two days unless I have been doing something that has meant they have become really dirty but I will never wear them more than twice before washing them. In the summer and warmer months, I will never wear clothes more than once before washing them. I always change my underwear daily though, that never gets worn more than once before being washed no matter what the time of year.
