Tron costume fits nice and snug
 

We’ve seen our fair share of Tron costumes and props, but much like [Sean-h] points out, they are usually pretty bulky and baggy. He’s gone a slightly different route by starting with a wetsuit instead of bulkier items like leather jackets. The lighting is done in the same manner we’ve seen before, copious amounts of EL wire and EL tape. The additional layers of this costume were made from foam, so they could be fairly form fitting as well.

[Sean-h] points out that there are some downfalls to his design. The wetsuit, while looking great, gets pretty hot while indoors and the foam layers have a tendency to detach if you move around too much. We think it looks great though.
