I will be doing this in a Heian style: the Heian 12-layer kimono... this will be faked somewhat due to the impracticality of wearing twelve layers!
I'll be making the forehead circle and the backplate with foam. The forehead design will be implemented into a hair piece. I'll probably also incorporate a pair of white wolf ears into the hairpiece. Hair itself will be tied back loosely (again, Heian style).
Makeup will be inspired by the Heian era, but not accurate!
Shoes - geta sandals with flower weaving over the top layer.
Props and accessories - giant paintbrush, magatama, String of Beads, hairpiece (as above), flame backplate.
