Unplanned Nudity
 

Unplanned nudity is nudity at an event in which the subject is willingly nude but did not attend with the expectation of getting nude. It’s not accidental or voyeur — they chose to be nude and seen. They just didn’t plan to.

Examples include: unstaged dares and party games, spontaneous skinny dipping, some theater and performance art events with audience volunteers, bystanders at WNBR-type events that join in, and similar.

My favorites include the women who join in with the nudists at the Fête de l'Humanité (kinda had to guess which ones):

This thread is off to a great start. I love the two group pics you included with the women standing with their backs to the camera.

I've seen it quite a bit at nudist get-togethers. Someone's wife or friend attends (out of curiosity or some sense of obligation) with no intention of getting naked themselves; but then get talked into it somehow. Their initial reaction is usually one of stupefaction: "OMG; I'm naked in front of everyone!! How did that happen?!?" along with an adrenaline rush. That wears off progressively; especially when everyone around is also naked anyway.

But that initial reaction is usually funny. They've underestimated the "power" of contagious nudity.

Various Unplanned Nudity
 

This is a great idea for a thread. He’s some various pics of random skinny dipping, dares, or women who decided to get naked for whatever reason.

This one is kinda iffy — the four leftmost girls were on a well-documented cruise and at one stop popped into a nude beach. It’s not clear if they left the boat that day planning on going there or decided in the moment, but it’s a good enough pic I’m gonna go with the more fun interpretation.

Two more handy ones. One naked event bystander stripping off, and one who came clothed dropping shorts.

If they’re stripping in the water, it’s probably spontaneous.

came here to post that exact pic of the woman dropping her shorts... such a hot photo

State of her knickers mind, excited a tad?
