Defining a kilt

[Nick]

"What's in a name? That which we call a rose
By any other word would smell as sweet."
Romeo and Juliet

"What's in a name? That which we call a kilt
By any other word would swing a pleat."
Bear

I raise my glass to you for that!

If it has the general form of a kilt, and is tailored for a man to be worn as a man's garment, then it is a kilt.
