I had formerly made this red “futch” harness sized for myself as an alternative to bulldog harnesses (a ubiquitous FSF accessory that has become).
I think harnesses look best when they accentuate the lines of the body (like a mesh on a 3D model, or a not-quite-anatomically-correct skeleton).
To complete the look I quickly knocked out a leather belt and A. ordered tactical hardware to match the silver/red theme.
