Unusual Kilt

[Piobair]

Shouldn't the extra material be added lengthwise rather than widthwise? I'm having a hard time figuring out how the apron would be positioned. It looks sort of like it could be wrapped around so the pleats are in the back and then there's a long underapron that runs to the back and is pulled up from under the waistband. I feel like that might look a little weird - you'd either have too much material hanging under the apron pleat or not enough.

In other words - what a weird thing.

Edit: Actually, I think I see what Richard is talking about. The "Braveheart rustic wool ancient kilt" (oh boy) from Celtic Croft appears similar - on theirs, it looks like the apron just gets wrapped up the body (sort of). Is there some kind of liner in the photo? Are we looking at the interior or exterior in that photo?
