One of the wonderful things about comic books is that there about a million characters to pull costume inspiration from. Maybe a bajillion. RPF user madprops focused his efforts on building a steampunk version of Gunslinger Spawn. He used a lot of leather, cast skulls and spikes, and incorporated LEDs to for extra flair. Here’s what he did for the coat:
Moving on to the coat. The base of the coat was a black Wilson’s leather trench coat I found at Goodwill for $25. Great find! The rest of the coat was hand stitched and tooled. I had to use a vinyl spry paint from DuPont and Nulife to get the red colors. I used a 1/8″ thick x 1/4″ wide aluminum bar in the collar sandwiched between 2 pieces of leather to get the shape in the collar. Hand stitching the coat was a heck of a task. Took me close to 3 weeks just to put all that together.
