Incidentally, there is a large amount of information (links) on pattern-making software here: http://www.costumes.org/computer/1pa...erprograms.htm
Note that this is a costumers website. I would think there may be numerous costume patterns that could be adapted to making rubber garments! Imagine things like formal Renaissance, Baroque or Gothic gowns in latex! What would Shakespeare or Louis XIV wear if they were Rubberists and latex was available in thier time? Someone could have a lot of fun with this!
