Is it mandatory to be full nude on the nude beach side?

No, it isn't. Being nude is a choice.

You can wear a bathing suit you can wear jeans you can wear absolutely nothing at all you can wear a bottom with no top on top of no bottom and anyway you want as long as you are on the nude side of the beach not the family side
