四分比丘戒本疏 2.114

2.114

第二、著三衣戒，亦五相犯：一高者過脚[跳-兆+專]上；二下者露脇；三象鼻謂左肘外垂一角也；四多羅樹葉謂通肩帔時後褰而前垂兩角也；五細襵安緣。

Second, the rule on wearing the three robes also has five characteristics of offence: first, too high, exceeding above the calf; second, too low, exposing the armpit; third, "elephant's trunk", meaning dangling a corner outside the left elbow; fourth, "palm leaf", meaning when covering both shoulders, tucking up the back and letting two corners dangle in front; fifth, fine pleating to affix the border.
