OK, I'm in on the search. Admittedly, it's in part because I've got my own plans for a costume for DragonCon, and searching for this stuff might parallel some of the accessories I need for my costume.
I'm seeing three parts to the costume:
- A long-sleeved undershirt.
- Flight suit/jumpsuit with sleeves cut off. This might be a set of coveralls (which I'm pretty sure would be the right color), although they wouldn't have all the pockets and zippers and stuff (you might be able to sew some of the pockets and stuff onto one, if you weren't afraid of totally screwing it up.)
- The vest, which I'm pretty sure you could find at an army surplus store. I know I've seen ones like it before. I think dad used to have one from the marines (color was different though), but I can't remember, and I can't remember if there was some specific name for it
