The clerical costume of the Sha-mên (Śramaṇas) is only the three robes and the Sêng-kio-ki and Ni-p'o-so-na. As to the three robes the Schools adhere to different styles having broad or narrow fringes and small or large folds. The sêng-kio-ki goes over the left shoulder covers the armpits, joined on the right and opening on the left side and in length reaching to below the waist. As to the Ni-p'o-so-na, since no belt is worn when it is put on, it is gathered into plaits and secured by one of these, the size and colour of the plaits vary in the different schools.
