Well... start here: http://www.thedentedhelmet.com/showthread.php?t=3342
The links to the main part of her site are working... just not some of the specific parts. Still some great information. IceHeart still has the Reference CD...
There are a couple of threads about the neoprene undersuit scattered about the forum. Nobody makes them. The colors you see ZIA wearing or MonCal's wife wearing were from a couple of custom neoprene runs that ZIA made before which she won't be doing again. There are a couple of companies which make some pretty close looking neoprene which you can buy and make your own suit. JDFett found one (and I can't remember the name of it...) Use the search function to find that info.
But you'll have to sew it yourself or hire a seamstress to sew it for you.
