四分律比丘含注戒本 2.219

2.219

The Buddha was in Śrāvastī. Kālodayin made a saṅghāṭī for [an unrelated bhikṣuṇī], cutting it into lewd shapes. When finished, he gave it to the bhikṣuṇī and had her wear it at the rear of the assembly, giving rise to ridicule and laughter from the laity. The bhikṣuṇīs reported this fault to the Buddha, who instituted this rule on account of it.
