The debate between “is she empowered?” And is she “sexually self objectifying herself for the male gaze?” Is a question that has to be answered on a case by case basis.

But generally, the desire to sex-it-up on Halloween is NOT tied to so much to the former as it is to the latter. The argument that tries to say, “wear whatever the hell you want” would hold more weight if it were applied all 365 days of the year.
Quite the conundrum.
