All pieces have more or less the same metal color and the leather color dyes the same way.
I think the Arch Demon Horns looks pretty dope but you can use a Brass Circlet of any kind to have a head piece that meshes well with the mettalic bits of the rest of the outfit.
Looks better with Jet Black or any of the metallic dyes.
Technically a bikini armor, but looks different for lalafells.
