Help for a kilted skirt for a bigger woman

[Pleater]

Kilts tend to reference the style values of an older time, and so an adult woman would not wear a short skirt.
When I think of a properly dressed woman from my youth they would be wearing a skirt with the hem below the knee - probably 27 inches as that is half the width of the wool fabric.
I went out this afternoon on a fine spring day in a kilt - just checked, it is 26 inches long - but at 5ft 4inches tall I am not very tall.
In my experience, a proper kilt - as in good quality wool and an actual tartan, is made with the right apron beneath the left, like a man's, though it might be a lighter weight fabric, longer and correctly shaped - it might even have an additional inbuilt petticoat or under apron for modesty. The maker would consider it a kilt rather than an ordinary skirt, and should observe the usual rules of pleating according to the set rather than randomly measuring out a series of folds using the minimum of fabric.
