Unfortunately my clothes tend to be a little too distinctive, not to say flamboyant, to get away with wearing the same thing for days on end; the garments are not interchangeable, and people really would notice ;-)

As a result I do try to leave at least a couple of days (during which people will probably presume I have washed them!) in between before attempting to wear the same thing again, which apart from any other considerations makes it more obvious if they have started to smell stale and need washing instead...
