Unisex dress code in Iran?

Iran has enforced a stricter Islamic dress code at numerous universities. This includes a ban on female students wearing long nails, bright clothes and tattoos.
The new rules ban women from "wearing caps or hats without scarves, tight and short jeans, and body piercing,"
It said tattoos, long nails, tooth gems, tight overcoats, and bright clothes were also banned.
Iran has been waging a country-wide campaign against Western cultural influences. Under Islamic law imposed after the 1979 revolution, women have to cover their hair in public and wear long, loose-fitting clothes.
The new code also bans male students from dying their hair, plucking eyebrows, wearing tight clothes, shirts with "very short sleeves" and jewelry.
