Old Christian women adopted Moorish veils partly to conceal illicit behavior.

Evidence

Whereas I have been informed that certain women who are Old Christians and live and reside in the city of Granada and in other cities and towns of this kingdom, forgetful of the general instructions to the effect that the newly converted should leave aside their Moorish dress and clothing, and should go about dressed in the Christian manner, themselves dress in the Moorish fashion, and cover themselves with almalafas,so that, in addition to the bad example which they set in this way to the newly converted, they, thinking that they are covered up, commit certain excesses and evil actions whereby Our Lord is ill served, and their own honor is jeopardized. — L. P. Harvey, Muslims in Spain, 1500 to 1614, 377

Categorization

• ADDENDUM: Directly extends ‘Complaints About Immodesty Go Way Back’ — here the veil functions ambiguously, as both a marker of cultural prestige and a cloak for transgression, exactly the class/political signaling dynamic that article maps.
• CANDY: A fun, tweetable paradox: authorities banned Christian women from wearing the Muslim veil because women used it to get away with things.
