Personally, I'd would want to avoid spandex for both characters.
It's more of a pleather. You can tell that it has more weight to it then spandex, with the poof at the ankle. Spandex is meant to hug the body, and there's enough room with Jeanne's outfit that you don't need it to be that close.
I'm guessing on the second one, but if that's the idea, I'd lean more towards pleather or a mixture of spandex for the black pieces and pleather or stretch vinyl for the redish fabric. Example: http://www.flickr.com/photos/ljinto/5985667198/
