There is a common misconception that the Burning Man Art Festival is a nudist event. This is not so. Rather, most burners wear fanciful costumes.
That said, it is true that the above-mentioned fanciful costume may -- at the extreme -- consist of... a hat. And only the hat.
One might say that the customary Western Culture modesty is suspended at the gate. Example: I was riding one of my pedal-vehicles, with two empty seats, when I met up with a couple who asked to ride with me. But they wore long flowing robes that would likely have gotten caught in the drive chains. No problem. They just pulled their robes off, stowed those in a bag, and rode nude.
This sort of thing is easily misunderstood by the sensationalist news media and many of their readers.
Maturity helps. You might be surprised at the average age of burners -- somewhere in the 40s, I believe. Education level likewise -- very high.
People need to learn that the news media is not a good source of information.
