The Monks Robe

Pali word for robe is "civara". The civara of Buddhist monks is called Kasava (or Kasaya) after the yellow stain applied to it. The Kasaya is composed of three parts so it is also sometimes also called Ticivara (literally the triple robe)

Antaravāsa
The antaravāsa is the inner robe covering the lower body. It is the undergarment that flows underneath the other layers of clothing. The Thais colloquially call it the sarong.

Uttarāsaṅga

A robe covering the upper body. This is the most visual part of the robe.

Saṃghāti

The saṃghāti is an outer robe used for various occasions.

The Buddha also observed that the padi fields in Magadha were partitioned into separate plots of land and made an attractive pattern. He then instructed that the upper robe should be cut up and resewn into a similar pattern, (apparently to distinguish the sangha from samanas of other religions and also to destroy the value of the cloth.). The robes are to be dyed with parts from plants and not from minerals or cow dung as was done by other samanas.
