Wondering what an AT-ST is? They are commonly called "chicken walkers" because of their two-legged gait. They are the vehicles seen walking through the forests of Endor in Return of the Jedi. Ewoks take them down on an embarrassingly regular basis.
Anyway, I did virtually none of the work on this costume. The coveralls and helmet were purchased ready-made, and the gloves and belt are the same ones I use for my officer uniform. I had to take a couple of buckles off of the boots and paint the commpad that goes in the pocket on the left forearm, but that's about it.
