It is technically legal to be naked in public in Spain based on court ruling but I dont see most Spaniards rushing to go shopping naked in public. This seems like much of an obsession by a tiny group of people with limited things to do in life.
Legality is one thing; breaking social norms is another. For example, it is legal for women to go topless anywhere it is acceptable for a man to go topless in Colorado and any of the other five States covered under the 10th Circuit Court of Appeals. How many topless women do you see at public pools -- zero that I am aware of. It is perfectly legal. Now granted, I wonder how many women are aware of this freedom. It was the Free the Nipple movement that won this case.
It is a similar situation in New York State courts have ruled that women can be topless in any public place that men can be shirtless. However I have been to Coney Island, Jones Beach and Central Park and saw no topless women at the first two and only a handful at the third.
So if it was legal for men to go naked in public in public places, would the response by men be any different? Women do tend to be more private about their nudism.
No, the response is exactly the same. In the UK public nudity is legal but neither sex walk around nude despite what some here claim or fantasise about.
Nudist do have organised events such as swims and woodland walks, and they police their own groups to make sure perverts claiming to be nudists are quickly identified and rejected. Sometime reported to the police.
Solo nude (its always men) woodland walkers have a much more difficult time explaining themselves if seen and challenged. Claiming nudity is legal and identifying as a nudist is not the get out of jail free card some here think it is.
