I have noticed several times on Ebay old A&SH and Seaforth kilts being sold the pleats of which have obviously not been pressed in a long time and have lost all semblance of an edge. These pleats sort of look like a series of tubes across the back of the kilt, or more like a ruffle than kilt pleats.

The way military box pleats lie is complicated so I can imagine somebody wishing to spruce up their kilt by pressing the pleats but not knowing how to do it.
