I counted 18 pleats between the buckles on the Black Watch picture. They appear to be about 1 inch wide. What is puzzling is they say it is an 8 yd kilt. Don't know how this can be unless the depth is considerable (more than 4 inches) which I would doubt. Others on the forum that are more knowledgable would know. It may be worth looking into for a casual knock-around for $58.00 plus shipping (you have to email to find that out). You can make an offer and may be able to get it for $60 or less total.
They have quite a few so if you get one I would like to see a review before they are all gone.

Cheers! Bill
