In modern usage, hijab generally refers to various head coverings conventionally worn by many Muslim women. It is similar to the tichel or snood worn by Orthodox Jewish women, certain headcoverings worn by some Christian women, such as the mantilla, apostolnik and wimple, and the dupatta worn by many Hindu and Sikh women. Whilst a hijab can come in many forms, it often specifically refers to a scarf wrapped around the head, covering the hair, neck and ears but leaving the face visible. The use of the hijab has been on the rise worldwide since the 1970s and is viewed by many Muslims as expressing modesty and faith; it has also been worn for purposes of adornment. There is a consensus among Islamic religious scholars that covering the head is either required or preferred, though some Muslim scholars and activists point out that it is not mandated.

A chādor, also variously spelled in English as chadah, chad(d)ar, chader, chud(d)ah, chadur, and naturalized as, is an outer garment or open cloak worn by many women in the Persian-influenced countries of Iran, Afghanistan, Kashmir, Pakistan, and to a lesser extent Tajikistan, as well as in Shia communities in Iraq, Bahrain, and Qatif in Saudi Arabia in public spaces or outdoors.
