The single biggest reason I don't make very much men's clothing, and vehemently avoid making uniforms from almost any era pre WWI, is the cost. Unlike civilian garb, which can be made of an almost limitless variety of accurate materials, uniforms have a very narrow window of "correct". As much I adore researching 18th and 19th century cultural history, I still cannot understand the mentality that existed behind making these uniforms so ornate and--by extension--expensive. A garment that men were going to live in for months or years, that would be drudged through rivers and mud and blood... and it's covered with no less than 45 expensive brass buttons, contrasting lapels and skirt flaps that serve no purpose but to add another expense of wool fabric. It simply boggles the mind. I try to imagine the kind of discussion around something like this.
Military Official: We need a uniform for our war of independence from the decadent and greedy British who have been taxing us to death. Men will die in this garment for our freedom!
Guy Who Is About To Add an Expensive Line Item to the War Budget: Buttons. Tons of buttons that don't actually button anything closed. Oh! And a flashy contrast, you know...to confuse the enemy.
