We're going to get all silly about this kilt/skirt word again. Best wishes aside, get used to it, a kilt is a type of skirt. It's a type of skirt called a kilt whether it's worn by a Catholic schoolgirl or my grandfather in the trenches.
It's what's inside that counts.

Granted my grandfather's kilt is going to heavier than the schoolgirl's, and that would be part of my defining. However, bear in mind that my grandfather's kilt would be far heavier than anything available on the market today so we're back to square one.

Vocabulary reflects ideology: break free from the limitations of the word as well as the clothes. Get over it, move on, that part of life really doesn't matter. Enjoy the breeze.
