Zipolite is supposed to be a nude beach, so why in all the images I find almost everyone wears a swimsuit?

It says everywhere that Zipolite (in Oaxaca, Mexico) is a nude beach, but every time I look for pictures anywhere on the Net, everyone or almost everyone is wearing a swimsuit. What's with that? I'm not looking for pictures of naked girls; I'm planning a trip and I want to know what to expect.

And, what's the best time to go? Regarding amounts of people, mood, etc... what's the best time for a person or a couple to go and get comfortably naked.

Jokes and stupid answers please refrain.

Probably because most people do spend time at the beach with swimsuit in the ON position. I think you have to understand that clothing optional beaches in Mexico are rare, don't believe any public Playa's are legal. That said it doesn't mean you won't find places where clothing optional is "Tolerated by the locals". Zipolite has the reputation of being one of those destinations where a beach allows clothing optional activities. There is a rather pricey private place south of Puerto Vallarta that offers a beautiful stretch of beach as clothing optional to its guests. I believe its called Punta Serena, never been there but its strictly for registered guests.
If look hard enough in Mexico you will find a few places where people go to enjoy the sun without a suit but they usually keep that information to themselves. Time? When the sun is high.

Good luck

I was in Zipolite last easter, only saw one naked person (she was fat and old!) Nudity is not permitted, but tolerated. Zipolite is full of hippies and new age stoners, not much else to do there and the sea is really rough. 10 minutes south is a town called Puerto Angel, this is a nicer place to visit if you want slightly better restaurants and accomodation, but it is still only really a fishing port with very little tourist aimed activities. North is Puerto Escondido which has better nightlife, restaurants, hotels, etc.
