I need a bit of help.

I know that some of you guys belong to other costume groups (rebel legion, and 501st to name the "big ones") and I was looking for some advice or some direction into making a costume like Corran Horn's from the cover of I, Jedi. I know it's probably based on some sort of flight suit, I was just wondering if anyone knew what one, or if it was just dreamed up by the artist if anyone has incountered one that looks similar. If you don't know what I'm talking about, here's a pic. I know that it's grainy but it's the best I could come up with.
