The Fraas of Neal Stephenson's "Anathem" wear a "bolt".
What do they look like? I'm having a hard time visualizing its basic shape.
Is it like a monk robe, or just basically a square of clothing like a roman robe, or like a Panchakacham?
It is said that they can wear in imaginative ways (like Fraa Lio in the episode with the ants.) Sometimes it reads like they have a hood or something on it, and a little rope to maintain everything in place but I'm not sure if the rope is at the neck level or the waist.
I'm not a native English speaker so maybe that word is too unfamiliar for me to be able to precisely visualize it.
