While Traditionally 'Gender Crossover' Roles Have Been Explained as Conservative

While traditionally 'gender crossover' roles have been explained as conservative, cross-gender performances can be subversive when:

A) conformity to the idealized gender role is purposefully incomplete or poorly executed, and that incompleteness or poor execution is highlighted as a key part of the performance.
B) conformity to the idealized gender role is perfect, for instance in terms of idealized age, attire, and ability to move like a 'real' woman (or man, as the case may be) .
C) common and therefore unremarkable.
D) nobody elects to take on those roles.
E) a culture dictates that females rather than males be the ones to take on cross-gender roles.
