"Gharbzadegi" ("westoxification") or western cultural influence stubbornly remains, entering via (illegal) music recordings, videos, and satellite dishes, despite government efforts. Compulsory hijab (veiling) for women has been given extensive police enforcement, Shorts, necklaces, “glamorous” hairstyles, and neckties (in government buildings) are forbidden for men. Western music is banned even more thoroughly, but observers note it is nonetheless popular and widespread. One post-revolutionary opinion poll found 61% of students in Tehran chose "Western artists" as their role models with only 17% choosing "Iran's officials."
