What is 'good moral taste'?

[Torchwatch]

Morality is defined by the eye of the beholder.

ISIS consider it moral to sell girls and young women they capture into slavery as wives from the age of 9 years upwards. ISIS consider it moral that girls be married between the ages if 9 and 17 years. Yet consider it immoral to see any part or a woman's body.

These definitions of morality clash with FINA's swimwear rules. ISIS is unlikely to produce any great women swimmers.

A swimsuit could be designed specifically to satisfy FINA's swimwear rules and yet could seem indecent to officials and spectators. Rule GR5.1 is a catch all rule to cover the unexpected and unimaginable. No one expected swimmers to wear full body suits that never got wet and the rules had to be changed to ban them.
