The thing with the King dressing in the uniform of Karl is actually a true story, and he had the high gentlemen helping him to take the uniform on(!) It was a great honour in those days to help a King to dress himself. The great Swedish-Finnish poet
Runeberg has ridiculed the farce in a famous poem:
"You, Piper, will help Us to get on one of his gloves;
you, Lagerbring, treat the other one the same way thus.
Field-Marshal Toll, your age and honour make you worth,
to fasten around Our waiste his victorious sword."
