"There is always a crackdown at the start of summer as women start wearing more skimpy clothes because of the hot weather.
In past years the pressure quickly relaxed - headscarves become perched on the back of heads, while fashionable women in affluent north Tehran wear open-toed sandals, three-quarter length trousers and short skin-hugging overcoats.
The police complain that some young women strut the streets looking like fashion models - and it is not a bad description.
]]> But this year the crackdown seems more serious.Iranian television has broadcast nightly programmes warning women and young men with sleeveless T-shirts and spiky hair to be more careful about their dress.
The head of the Iranian judiciary, Ayatollah Shahrudi, has warned that a severe crackdown on un-Islamic dress could have the reverse effect.
Meanwhile, an MP has asked why the police should spend so much time arresting young people and filing court cases against them instead of fighting drug addiction and poverty.
Already taxi drivers say there are fewer women on the streets and it is clear most are dressing more conservatively."
