四分律行事鈔資持記 3.127

3.127

餘衣中，初科。偏袒謂止存左袖，袒露右邊，即本祇支。𧝡膊亦即覆肩。此二雖是聽衣，但乖本式。方裙，舊云女人上馬裙；諸裙，自餘裙襜等。《業疏》云：且順律文，非俗非外。（準方俗所宜，義應得著。）

In [the section on] the remaining garments, the first heading: 'baring one shoulder' means keeping only the left sleeve and baring the right side, which is the original *saṃkakṣikā*. 'Covering the shoulder' is also covering the upper arm. Although these two are permitted garments, they deviate from the original pattern. 'Square skirt' was anciently called a woman's horse-riding skirt; 'various skirts' refers to the other skirts, aprons, and the like. The *Karma Commentary* says: 'For now we comply with the Vinaya text: neither secular nor non-Buddhist.' (Following what is appropriate to local customs, it should meaningfully be permitted to wear.)
