It is not unusual to see a person without any clothing at Swanbourne Beach but a local cafe owner is hoping to convince 1000 to people to strip off together at the beach in aid of a good cause.

Russel Morris and the other co-owners of the Naked Fig Cafe want to beat the world record for the largest skinny dip.

Participants will have to strip off completely and wade into the water at least up to their chest to be counted in the final tally.

Mr Morris hopes to get hundreds of naked bottoms to Swanbourne beach on March 30 in order to better the current record of 729 skinny dippers.

He said while the event was still in the planning phase, the City of Nedlands was "on board" with the idea.
