13 oz kilts

[Nathan]

If I understood the instructions correctly, the 13 oz is 7.25" and the 16 oz is 7.5".

edit:
I did take the tape out and measure along the bottom of the kilt from the fringe all the way along to the under apron including the bit that's folded over and sewn. My measurements came out to 6 yards and change. I've never heard of a six yard knife pleat kilt. Is this considered an 8 yarder even if there was some left over due to waist size?
