Only below the navel or on the private part also?
The area immediately under the navel is not to be shaven.
The area of shaving for a person (male / female) is above and around the
private parts. If possible, it is commendable to shave around the hind
private parts as well. (Al-Kaamil, commentary of Muslim; Imaam Nawawi vol. 1
