The Butterick pattern arrived today. I have read through the layout and construction instructions. It will work - with some modifications. The pattern is intended for a costume garment. It has no front facings and no lining except for the cape. That will not do for my purposes. For one thing, I want two interior lining pockets. I am also thinking about adding two large flapped hip pockets. Fortunately, the layout for 60" wide fabric has the sleeves end to end. I can use that part for front facings instead.
I'm done for the day. Cutting tomorrow...
