Iran's parliament today adopted a new controversial law that significantly tightens the existing dress code for women and men, which has already sparked protests across the country and shaken the stability of the Islamist regime, reports CNN. 

The new "chastity (virginity) and hijab" law has been passed by the hardline parliament and approved by the Guardian Council, which ensures the law's compliance with the Constitution and Islamic law.

The law, in order to enter into force, still needs to be signed by the president of the country.

President Massoud Pezeshkian, who is a critic of the strict dress code, has voiced his opposition to the law, bracing for a possible clash with conservatives who support the initiative.

His signature on the bill is largely ceremonial, giving him little room to block legislation. Pezeshkian admitted on social media that it will be difficult to stop the law.

The law introduces a three-year trial period during which tougher penalties will be applied for violating the hijab and inappropriate dress, for both women and men. It defines indecent clothing as clothing that reveals the body below the neck, above the ankles and forearms for women, while for men the ban refers to exposure below the chest, above the knees, as well as on the shoulders.
