There's Arkady's bargain flightsuits thread in the costume forum. I believe RKD has some larger armor, but personally, I would use the WOF templates and see what size works for you, then compare those sizes to his. I highly recommend Terminal Fettler's helmet. I had one before, and I thought it was just a tad big on me. As far as the shoes go. I have no idea if anyone makes shoes that big. Maybe contact evolution props? to see if they could accommodate you. Though their overall impression left on people is lack luster, people seem to think their shoes are ok. I normally wouldn't recommend them, but they're the only ones I know making boots right now. Aside from CA boots, who only go up to size 13.
