Why oh why oh why?
A generation too late to have detachable (stiff) collars -- thankfully - although my Dad had them when I was young. The raison d'etre for detachable collars was, of course, same shirt all week, but clean collar every day!
My children often wear the same shirts to school several days in a row...
...except they're now washed and dried (but not ironed - thank you, tumble dryer!) each night inbetween.
