I too am happy you are keeping the cape. Feel a bit of redemption, as it seems like lately I am in the minority with every opinion I offer

Especially since the history buffs agree. Of course I was being coy when describing the wife sewing the design for the whole chapter (see KKK hoods,
Django Unchained) but point was that a soldier at this time wasn't bound by the uniformity seen in later armies. Notwithstanding, aesthetically speaking it was just too large and too white to be left without character. The Cistine Chapel with a popcorn drywall finish. Yuck.
I think that as an historical painter, being accurate to the time and circumstances is important. But as I said before, this does not rob you of creative nuance. Even modern day militaries that pride themselves on disciplined uniformity contain soldiers with a strong, strong desire to stand out from the masses. A bandana, a different chinstrap, custom boots, rifle attachments, etc. we often call them geardos for their obsession with the flashiest customizable equipment. Silly comparison, I suppose, but I can't help but rationalize that all but the greenest soldier in any army at any time would equip himself with equipment or modifications outside of the basic issue. The challenge is to make the accessory an accurate and believable one.
