Sian occasionally like a bit of the shiny, but often finds that shiny clothes in SL are either so subtle that you can't see they're shiny, or frankly not subtle at all, so you get these latex suits with huge white splotches on them.
But try this: take a fairly standard solid "splotchy" catsuit, and stick a more subtle transparent one of the same colour on top... Sian really likes what you get. You might too.
