Codex Vindobonensis 8615, c. 1585
Muslim women in the Ottoman empire wore a combination of cloth items to cover their faces/eyes. These were primarily worn for modesty while out in public, as well as to protect from the elements. Christian women living in the Ottoman empire were known to forgo wearing these items. These items were never mandated by the Ottoman state. They consist of the Yashmak, Lisam, and Peche, which I will discuss here.
Yashmak and Lisam
Türkisches Manierenbuch c. 1595
The woman above is wearing a Yashmak and Lisam combination. These are two diagonally folded squares. The Lisam is the lower face veil; Yashmak the veil tied over the head. The Lisam is tucked into the head covering. You can see that clearly in the following image from Türkisches Kostümbuch. Of note, I have seen images with the nose both covered and uncovered.

Pece
The pece is a fine mesh screen, fastened over the eyes and around the head with ties, and sometimes beaded or embroidered. This was likely made from horsehair, though no surviving examples exist. This is always worn with the Yashmak and Lisam above.
