A ladies pleated hostess skirt is made exactly like a normal man's kilt with the following changes.
When you wrap it on the left apron goes around first so the straps need to be sewn on opposite. Then the right apron becomes the outer apron so you need to put the fringe on that edge.

In Barb's book the measurements for laying out the aprons are different for the under and outer aprons so just reverse those two.

Other than those three small things just do a normal kilt that is a bit longer.
And because it is longer you need to remember that the 1/3 rule for length of Fell no longer applies, just take a measurement for it.
