I found the costume on this image similar to MOS's one, especially at the level of the wrists, the height of the boots ( the missing shorts ).
and the belt (which looks a lot like Superman Flyby's one):
If you take a look at the Burton version of the suit worn by Nicolas Cage you can see that the wrists look marked and resemble to MOS suit's ones:
As far as Superman Flyby project is concerned, I wanted to share this picture who came out lately ( to whoever hasn't seen it yet ). I think that the design is really well done.
