Not necessarily; my wife has two from Scotland and they have (shallow) pleats at the back and aprons in front.crfriend wrote:[
If one looks at long "kilted skirts", one will find that they're usually pleated all the way 'round ...
By the apron problem, do you mean they restrict movement since the two aprons will not always slide smoothely one on the other (which does not matter on a short kilt). I did not notice that, and ladies often wear them for Scottish country dancing, where one needs to make longish strides.
I had one myself, but decided to have it shortened above the knee into a lightweight summer kilt.
