The bhikkhus have three robes while the bhikkhunis have five robes. What are they?
The five robes prescribed for the bhikkhunis are as follows:
Another requirement is the ‘monthly robe.’ which, though not included in the above five robes, is necessary for the bhikkhunis. This is used during the menstruation period. In the Buddha’s time material was not easily available, this ‘monthly robes’ belonged to the Sangha. Any bhikkhuni may use them when needed. Then must wash them clean and return them for the common use of the bhikkhuni Sangha.
Another piece of clothing not allowable for a bhikkhuni is ‘Sanghani.’ This is a decorated piece worn around the hips as commonly practised by the laywomen.
