well, just heard back from Puma. They said that the suits WERE custom made, and that the football shirt I have linked above is the closest they have to it. They said that the patern for that shirt was altered slightly to make the Island suit. The shoes are the only thing that was off the shelf.
My idea is to maybe buy the footbal shirt and some fabric and try to use the FB shirt as the patern. I dont know what type of fabric though...some sort of polyester?
