In The Mitzvot: the commandments and their rationale, Rabbi Abraham Chill attributes the following idea to Radbaz (without quoting him verbatim):
It is understandable why a man should not dress like a woman, because this would indicate a degradation. But why should a woman dressing as a man be condemned? Is she not attempting to upgrade herself? He [Radbaz] answers that when two souls are lowered upon earth, one of a woman and the other of a man, God intended them to remain distinctive … Any change in this pattern would be counteracting God's design and is therefore forbidden, irrespective of whether it is upgrading or downgrading.
Can anyone point me to where Radbaz said this? Many thanks.
