We've found an excellent source for enlisted women's OD wool service dress coats. This is the later war design with the square pockets on top, improved bottom slit pockets, shoulder epaulets, and eagle buttons. It is excellently tailored and is slightly long, so you can bring it in if you need to. For some reason, the liner is a more modern satin, which won't detract while it's being worn. The material matches originals very well.
The supplier also has the skirts. For some reason, my wife's husband neglected to order them. When we sell some more items, we'll stock the skirts.
This is a size 40.
