四分律比丘含注戒本 3.64

3.64

Among forms of untidiness: "worn too low" means hanging down past the elbow and exposing the flank; "too high" means pulled above the ankle; "elephant trunk" means letting one corner hang in front; "tāla palm leaf" means letting two corners hang in front while the back is hitched up high; "fine pleats" means pleating it and fixing the border. As for non-offense: if there are sores on the shoulder or arm and one wears it low, this is the same as the exemptions mentioned above.
