The US Air Force has updated its dress code policy to outline a clear approval process for Sikhs and Muslims who want to serve while wearing their articles of faith.The Air Force’s dress code was updated last week to provide an approval process for Sikh and Muslim service members to receive religious accommodations, allowing them to wear turbans, hijabs, beards and other items of religious expression. Staff Sgt. Abdul Rahman Gaitan in 2018 became the first Muslim airman to receive a beard waiver for religious reasons. Capt. Maysaa Ouza, the first Air Force Judge Advocate General Corps officer to wear the hijab, was also featured in a short NBC documentary last year.Airman 1st Class Harpreetinder Singh Bajwa in June 2019 became the first active-duty Sikh airman allowed to wear a turban, beard and long hair, which Sikhs tie in a bun and then cover with the turban.Beards can’t exceed two inches ― if they do, they must be “rolled and/or tied” to achieve the required length, the regulations state. Hijabs, turbans and under-turbans (also known as patkas) should be free of designs and made of a “subdued material” in a color that closely resembles one’s uniform. Religious head coverings are also required to be free of designs or markings unless the individual’s uniform has a camouflage pattern.
