It's intriguing, that the tricot neoprene color matches most of the the MOM shots, and KayDee's matches the FIDM shots. They had different lighting situations. But they could have been two different costumes. If you match the squares on the side of the costume, you could be able to check if it's the same skirt used. (I haven't checked) Anyone want to try?
It's doubtful asking Steve if he knows. Only someone who worked on the costume would know. That's like asking Leeanna, and we asked her tons of questions, she wouldn't have remembered that - she didn't even know there are hoses in the back of her helmet. IIRC- she just remembered that it was lycra that she wore.
