In France, modest beachwear is against the law (just for women)
Around where I live, on Monterey Bay, a lot of surfers wear wetsuits, which apparently are illegal in France, at least for women.
UPDATE: No, The Wife tells me, wetsuits are okay.
I think I can’t make sense of the law because the law doesn’t make sense. It’s an example of laws passed to show social disapproval of a group, not for any other reason. (One reason, I’ve read, that (alcohol) Prohibition did not work in the US is that the law was passed by Protestant rural majorities, who tended to drink little, to show their disapproval of urban Catholics, who did imbibe. Once the law was passed and the disapproval was shown, the public really didn’t care whether the law was enforced or not.
Anyway, I think one can reeasonably condemn the French law and whatever passed for the “thinking” behind it.
