There's not a name for it, except for paraffin. It is highly refined, and contains none of the impurities that are acceptable in candles.

As for the pleating issue... there's SO MUCH more to making the waist and hips measurements to the right dimensions. There's also MUCH more to making sure that the tartan pattern is consistant in the kilt.

What is OFTEN missed, is the method that it takes to insure that the pleats hang STRAIGHT and even. There's a third step in pleating that is often bypassed in kiltmaking... and it's essential for a quality hang and flow. That's a MAJOR difference in a "traditional" with the authentic craftsmanship, and a "formal" that has the basic looks without the sewing and pleating methods. As we've seen, there are a LOAD of "formal" kiltmakers around... and this is an easy designation between the two.
