四分律行事鈔資持記 2.1433

2.1433

釋不齊中。非法有四：初是高下。二象鼻。三多羅葉者，《西域記》云：形如椶櫚，用比兩角。四細襵者，止得前後兩跨為四襵，多則非法；今時蕈簡，同彼女流，非道服矣。

In explaining 'unneat': there are four improper ways. The first is high and low. The second is elephant's trunk. The third is tāla leaf: the Western Regions Record says, 'The shape is like a palm tree; it is used to compare the two corners.' The fourth is fine pleats: one is only permitted four pleats across the front and rear thighs; more than that is improper. The mushroom pleats of today are like those of women and are not garments of the Path.
