by unitard, i am assuming the one piece fencing suit, if this is the case, i have seen them at http://www.triplette.com/sport%20fen...and_unita.htm. i think they are made out of the same fabric that the normal jackets are made out of. the price ranges from $120 for a regular suit or $325 for FIE. i have never seen them used, so i am unable to help there. hope this post helps.
Unitards were an interesting idea that never really took off. YOu can get them from TCA (who are I believe the only company that manufactures them) Unless you have a perfect build they are kind of hard to get that fit well and don't look totally goofy. (But it can be done)
