This fusilier coat will be the death of me. With all the hooking and unhooking, rotating, and overall tightness, large hunks of plastic started falling out of my sewing form. The top of the neck opening is no longer straight. Hopefully, it will all hold together.
At the end of the 18th-century, British enlisted men's coats had fake pocket flaps, complete with regimental tape and buttons. The feeling was lowlifes should have as much trouble getting to their pockets as possible, but the coat should still look good.
When uniform re-issue time came around, regimental tailors cut the old coats apart, removed the tape, turned them inside out, and cut them shorter to clean up the ragged edges. The pocket flaps were also removed.
Second order coats (and light infantry/highland coatees) had vertical flaps--like wings. No buttonholes, but the buttons get the "hole poked, secured with linen tape from the backside" treatment. Since this is the drunk tailor, there must be a wtf moment after hours of labor.
