1.124

"Afterward, when the monks wore their kāṣāyas, they were mostly untidy. The Licchavis ridiculed them, saying: 'They have no dignified comportment; the garments they wear look like those of courtesans, just like elephant trunks.' Because of this, he first instituted the placement of the hook and loop, ordering that the corner of the robe be brought to the left arm and placed under the armpit, not allowing it to hang down, so as to avoid the faults mentioned above."
