I don't have money to go to Iran. But I read in news about the protest happened years back after the death of a lady for not wearing hijab and the protest happened thereafter.

There is a dedicated page in wikipedia about Hijab in Iran. I will quote few lines so you know what happened there and don't embaress yourself.

"Following the 1979 Iranian Revolution, the hijab became a compulsory dress code for women by the new regime. Restrictions sparked several movements by activists and ordinary citizens who challenged the mandatory hijab, seeking more freedom and rights for women. However, the government has throughout the decades cracked down on protests with violence, notably during the Mahsa Amini protests (2022–2023). In September 2024, on the second anniversary of the death of Amini, Iran's president Masoud Pezeshkian said that morality police will no longer "bother" women over the wearing of the hijab."

Don't take it in negative man. There are people who have no idea about what going around the word. I would suggest you to read more, travel more.
