An Egyptian queen wore a false beard as a symbol of masculine power but in the Middle Ages, swathed chins became an emblem of femininity.

The English started the trend with an early form of the wimple - a linen cloth draped like a bib, completely encircling the face, topped off with a veil.
Soon similar styles swept Europe, beginning with the popular barbette, a chin band attached to a pillbox hat. A married woman wore a gorget, an even more concealing bib, that stretched from the chest to the ears; and widows switched to a pleated version, the barbe.
The height of the barbe was strictly regulated by the sumptuary laws. Women of baroness rank on down wore their barbes below their chins; higher noblewomen wore them slightly above; and a queen wore a barbe that covered her chin completely.
Fashion became law in the 15th Century when, needing some explanation for the Virgin Birth, the Catholic Church decided that Mary conceived through her ear. Consequently, it decreed the female ear a sexual organ and demanded that women wear wimples at all times to keep their ears well covered.
