ohOH! let’s see if I can do this..
I’ve decided that his arm-piece is more of a portable record-player— basically THIS and THIS combined.
Weird details are that he wears his socks on top of his pants.. and has knee and elbow pads.
His collar is basically that of a tux..except a little more exaggerated!—and his soul gem rests right on top of the center of the bow-tie!
I hope that helps! andand GOODLUCK! We would love to see your cosplay once you’re done~!
