Rubber Ball
From wipipedia.org
Each October a weekend is organised by SkinTwo magazine, comprising an expo and several parties including the Rubber Ball itself. As its name suggest, this is a party with a dress code that favours rubber (though PVC and, for males, transvestism are common).
The 2005 skin two expo is Saturday 8 October 1.00 to 9.00 and Sunday 9 October 1.00 to 7.00 at The Barbican, City, London EC2
