I have some editions of Mueller.
The last - I think - is the 21. edition, printed 1993. (Dresses and blouses) Coats and jackets - there is a newer one.
It is very straightforward and very generally held. Not going into the different fashion stuff.
I have the 20. ed. too, bought in the 80ies. A very good one. And I think this books are all in use and nobody want to part with them.
Between these 2 is a huge gap. The 20.ed is done more for the custom tailor (like all the older ed.s) the 21 is leaning more to the industry. Understandable because it is the need of the reader and how the young tailors are educated nowaday. No use to close the eyes.
I like the old ed.s because they talk about a lot of stuff, which is now nearly forgotten. But they changed over the years some systematic drafting; example: deriving the bust dart width and other stuff.
If you went for: Hofenbitzer, Bekleidung, Schnittkonstruktion in der Damenmode. You'll get skirts, Trousers, bluoses and Dresses, Jackets all in one book . Modern - but the drafting is done very basic - without much going into fashion

or there were some typhos in the first edition so they put the right thing in the net. Good to see how it works:www.europa-lehrmittel.de/downloads-downloads/32/62369_1_korr.pdf/
you can see what you are choosing. It is surprisingly cheap. The drafting is nearly the same as Mueller.
If you want other systems there are many around.
