I wonder what "list" means in this context:
"Upon this Mr Casby rose up in his list shoes, and with a slow,
heavy step (he was of an elephantine build), made for the door. He
had a long wide-skirted bottle-green coat on, and a bottle-green
pair of trousers, and a bottle-green waistcoat. The Patriarchs
were not dressed in bottle-green broadcloth, and yet his clothes
looked patriarchal."

My copy of Little Dorrit has a note saying:

list shoes: Shoes made of thick cloth (the strips of selvaging or waste borders from cut bolts of fabric).
