A guy with a lot of time to spare created his own TRON costume:
I saw lots of TRON costumes on the net, and wasn’t satisfied with any of them. The biggest deficiency was that none of them attempted to capture the green tint of the characters’ outfits in the computer world. Yes, I know that was added in the digital animation process, but, still, a white costume just doesn’t look right. Many of them also used black for the circuit patterns, one more step away from the costumes the viewer saw in the movie.
I decided I could do better, at least to my own way of thinking. This is not a slam on those who have gone before by any means, just an observation that I could resolve what I saw as deficiencies.
