Viking clothing question

[stitchwhich]

Do you know what I've been wondering? On the pleated hangerrocs, which way did the pleats fold? Yes, I know that they were 'open' towards the underarm on one apron, but - how about the others? And is there an extant piece that indicates whether or not the pleats changed direction at the middle of the apron or if they all headed in the same direction all the way across?

These things are how I spend my day-dreaming time...
