You could certainly use my book to make a hostess skirt, and it would come out fine, and there are plenty of instructions in the book for shaping a kilt to fit a woman. The issues are no different than making a kilt for a female dancer.

Having said that, most hostess skirts are made quite differently than traditional kilts. Here are the typical differences:

-much less material
-lighter weight material (10 oz or even 8 oz)
-pleats stitched by machine
-fewer pleats with no attempt made to pleat either to stripe or sett
-no lining because the pleats aren't cut out and there's typically no canvas interfacing.
-fringe edge on the left instead of on the right
-essentially no rise

The net result is something that looks a lot like a kilt but is less heavy, less bulky, and much less expensive. Folkwear Pattern #152 has a pattern for a hostess skirt (also called a kilt skirt). You can see the pattern at http://www.folkwear.com/152.html

And, having said all this, there's nothing wrong with making a long kilt in traditional fashion for a woman.
