This is Sir John of Severn, leader of the fighting company I mentioned in that post about the Japanese jin-baori. Every member of the unit has at least one outfit done in company and kingdom colors, but in the style of their persona, be it English, Japanese, German, etc.
The whole thing is heavy linen, and unlined. It's also quarter-charged (divided quarterly, as opposed to having a gold half and a black half). I sewed the surcote and the appliqés (stars and lions); another friend of his painted the company's motto around the bottom (Ut simus invicti: "together we are invincible").
There's more coming, too, on this front, in future posts.
Stay tuned. :)
