Once again in my opinion for the location overdressed but it does seem to draw your eyes to the prize
I don't agree with you.
Did you ever visit Cap d'Agde Naturist Village?
If yes you would know better. On behalf of the evenings the dress code was to be sexy as possible.
Public sex is forbidden. Police is walking around.
Yes, on the beach (also forbidden to have sex but that is denied), and f.e. the foam party or in (private) clubs, it is quite different.
