Can't find the video again but there was a short clip with the costume designer and she was talking about the materials used. She advised that every fabric they used was actually synthetic! I want to say she described Flynn's inner robe as being a polyester that just looked like it was linen. It's a pretty great effect but I'm sure it was probably all custom manufactured.
I'm with CalaveraJoe. Being a "full figured" woman there was no way you'd get me in to an all spandex and rubber suit. ^_^ I think the robe approach is more suited to my style anyway. As I'm not planning an exact replica of the outfit I can play with it a bit.
I wanted to share the attached image because it shows off the design on the back of Flynn's robe. Being from the video game it is likely not 100% accurate but it shows structurally the lines and slits better.
Is there a decent source for wider EL tape out there? All of the stuff I have on hand is a bit narrow and I'd rather have 1 1/2 inch or 2 inch wide strips to start with than double up and try to conceal the line. I'd really like to just get a spool of the wide stuff and wire it up myself.
