What is the shape of Tang priest's cassock?

The cassock is a rectangular piece of cloth with the same length on the opposite side and different lengths on the adjacent side.

The cassock is made of some small pieces of cloth, so it is also called tailoring. Looking at its image, the cassock is like a terraced field in the countryside, piece by piece, so it is also called Futian clothes. The cassock made of red satin is embroidered with gold thread into a brick pattern. One end has a wishful hook, the other end has a jade ring, which is hooked up and down on the chest, and the main part is placed on the left arm.
