There are contexts where naked dating is appropriate. Like Burning Man, I guess.
I remember I engaged in some music festival where people danced completely naked with art on their bodies. We talked to each other in a bar. This is definitely the appropriate context.
Somehow due to the art, it seems like people are dressed until you take a closer look. Depending on how exactly it's organized, I can highly recommend it; it was a fun, trippy experience for me.
I don't know whether it's effective for dating; I went there for a different purpose.
