Regarding kilt length....

An inch is irrelevant, IMHO. I wear tartan kilts that hit me at the top of the knee, in the middle of the knee and at the bottom of my kneecap. If you don't like where it hits you at the knees, hike it up an inch or yank it down an inch.

While an inch is irrelevant, even an inch and a half, THREE inches is not, in my opinion.

I know, horrors.
