The History of Sex: Seville -- Beware Satanic Fashions! -- (Chap. VI, Pt. 11)

So it was that students in seminaries and religious colleges were told to beware the 'diabolical serpent' of the penis and the 'Satan's den' of the vagina.

As in medieval times, books on morality divided the female body into three zones: the 'honest' or 'decent' parts (the hands, feet, face and arms up to the elbow); the 'less decent' bits (such as the upper arms); and the downright 'indecent' bits.

The Archbishop of Toledo issued a dress code declaring that 'it's against modesty not to wear stockings,' while posters warning against the evils of MODERN DANCES showed a besuited young man waltzing unknowingly with a horned and winged devil, as a woman in a dress does likewise.

('YOUNG PERSON… AMUSE YOURSELF ANOTHER WAY' it commanded, though it must have been a toss-up between close dancing and masturbation.)

All the media were censored, and most magazines and newspapers hired touch-up experts to doctor photos.

Gone With the Wind wasn't shown until 1950—eleven years after its debut—and even Biblical fare like Samson and Delilah had to be made decent for los españoles (the temptress' midriff was covered up in posters).

However, just as Goya had dodged the old Inquisition by painting a double portrait of La Maja (one nude, the other clothed), Spanish filmmakers found a way around Franco's censorship: shooting two versions of the same scene.

In The Return of Clint the Stranger, one of many spaghetti Westerns shot in Spain, the international version included a scene with a blonde lying on a bed, exposing everything from her breasts to the top of her pubic triangle.

In the Spanish edition, a sheet covers her up to her armpits.

What with modern Spain's fame for 'Ibiza Uncovered'-style debauchery, it's hard to fathom that one of the main battlefronts in the war on sin was the country's beaches.

Up until at least the Fifties, many swimming areas were divided between the sexes: boys would have to bathe separately with their fathers, and girls with their mothers.

In Las Palmas, the bishop ordered his priests to deny absolution to anyone who insisted on playing on la playa in mixed company.

As late as 1976—a year after Franco's death—a religious magazine in Valencia denounced 'Satanic Fashions:'

Bikinis and tight trousers
Mothers sin by buying them for their daughters.
The girls sin by using them.
Men sin by looking at them.

A modern condemnation of 'infernal fashion':
Woman: 'Hey! Why are you cutting my dress?'
Demon: 'It's to make you more attractive...
but especially to send men to hell!'
